That single layer covers brackets, braces, and the symbols most common in C-family and web languages, accessed without moving hands off the home row. Corne builders typically need two or three layers like this to fully replace a standard keyboard’s dedicated keys, while ErgoDox EZ owners often get away with one, since the base layer already has room for most of the same characters.

How These Compare to Mainstream Ergonomic Keyboards
ErgoDox EZ, Corne, and the Preonic Rev 4 are not the only ergonomic options a programmer will run into while shopping. Boards like the Kinesis Advantage360 Pro, the ZSA Voyager, and the MoErgo Glove80 occupy a more turnkey, higher-price tier of the same general idea, typically with deeper contoured key wells, wireless support out of the box, and a single polished configurator. Mainstream mechanical boards from Keychron and similar brands, meanwhile, keep a standard row-staggered unibody layout but add hot-swap sockets and better switches than a typical office keyboard, without asking a buyer to relearn hand position at all. For a broader roundup of that wider category, including boards outside the DIY and ortholinear niche covered here, see our roundup of mechanical keyboards for programmers.
What separates the three boards in this comparison from that wider field is price and philosophy rather than raw ergonomic benefit. Corne in particular is priced closer to a hobby project than a peripheral purchase, and building one from a bare PCB is itself part of the appeal for a meaningful slice of its audience. Programmers who want the DIY experience to extend beyond just this comparison, building an entirely custom board from scratch rather than a kit built around an existing open-source PCB, can find the general process in our guide to building a custom mechanical keyboard.
Firmware Face-Off: QMK, ZMK, and the Oryx Configurator
Firmware is arguably a bigger differentiator between these boards than the physical layout, because it decides how much of your workflow you can reprogram. The ErgoDox EZ runs on QMK, but ZSA wraps it in Oryx, a browser-based configurator that compiles firmware in the cloud so nobody has to touch a command line. That convenience costs some flexibility: you are working within ZSA’s maintained fork of QMK rather than the bleeding edge of the open-source project.
Corne is where the open-source firmware ecosystem is most visible. Builders can flash either QMK or ZMK, and the community leans toward ZMK specifically for wireless builds, since it was designed from the ground up around Bluetooth Low Energy. The QMK project sits at roughly 20.7k GitHub stars and more than 44,000 forks as of early September 2026, according to the qmk_firmware repository, while ZMK’s repository has around 3.5k stars, per the zmk repository on GitHub. Corne’s own hardware design repository, crkbd, has separately accumulated 7.6k stars and 1.1k forks, tracked by SrcLog’s open-source metadata tracker. That is a large, active base of shared keymaps and layout configurations to draw from instead of starting from a blank file. The Preonic Rev 4 runs QMK directly on its onboard RP2040 chip, giving it the same underlying firmware as the ErgoDox EZ, without the Oryx wrapper. That means more manual setup, but also fewer platform restrictions for anyone who wants to hand-edit a keymap.
For programmers who already spend their day in a terminal, this is not a small distinction. Custom firmware and RP2040-class microcontrollers are part of a much broader hardware story this year, running alongside the same category of low-power chips showing up across the wider AI PC and edge computing hardware market covered in our 2026 AI chips coverage.
Pricing Breakdown: $30 DIY Kits to $365 Pre-Built Boards
Price is where this comparison gets genuinely wide. Here is what each board actually costs across its available configurations as of September 2026.
| Tier | ErgoDox EZ | Corne (CRKBD V4) | Apos x OLKB Preonic Rev 4 |
|---|---|---|---|
| Entry / bare kit | N/A, sold assembled only | ~$30–$48 (bare MX hotswap PCB set, Beekeeb) | $150 (barebones case + PCB + plate) |
| Mid configuration | ~$295–$325 | ~$178 (pre-soldered Choc low-profile board) | $170–$185 (keycaps or switches added) |
| Fully loaded | ~$365 (Glow, full extras) | ~$227–$348 (pre-soldered wireless MX build) | $205 (full keycaps and switches) |
| Assembly needed to reach that price | None | Soldering for bare PCB tiers only | None |
Sources: Try Ortho Keys, Beekeeb’s Corne storefront, and Try Ortho Keys’ OLKB buying guide.
That spread means the gap between the cheapest usable Corne kit and the most expensive ErgoDox EZ configuration runs as high as $335. Even comparing pre-built, ready-to-type options rather than bare PCBs, a pre-soldered Corne still lands around $178 to $348, meaning it can be either the cheapest or the most expensive of the three depending on which wireless or case configuration is chosen. The New York Times’ Wirecutter has flagged the ErgoDox EZ’s pricing directly for years, noting it “starts at $350, considerably more than most other keyboards we recommend,” in its ergonomic keyboard guide, though current 2026 retail listings show it available from roughly $295 depending on configuration.
Benchmarks: Community Size, Ecosystem Support, and Build Data
Mechanical keyboards for programmers do not have frame-rate benchmarks, but they do have measurable proxies for how supported and mature a board’s ecosystem is: GitHub activity, vendor availability, and how long a design has stayed in active production.
| Metric | ErgoDox EZ | Corne (CRKBD) | Preonic Rev 4 | Source |
|---|---|---|---|---|
| Firmware repo GitHub stars | 20.7k (QMK, shared) | 7.6k (crkbd design repo) plus access to QMK/ZMK | 20.7k (QMK, shared) | GitHub / SrcLog |
| Years in continuous production | 10+ years, no discontinuation | Actively revised through 4 hardware generations | Relaunched Aug. 2026 after a 3-year gap | ZSA, KBD.news, Try Ortho Keys |
| Warranty length | Up to 4 years (extendable) | Vendor-dependent, often none on bare kits | Standard retail warranty via Apos | ergodox-ez.com |
| Vendor / purchase channels | 1 (ZSA direct) | 4+ community vendors (Beekeeb, PandaKB, Ergoboards, and others) | 1 (Apos direct) | Beekeeb, Ergoboards, Apos |
The single-vendor model for the ErgoDox EZ and the Preonic Rev 4 means consistent quality control and one place to go for support, but no competitive pricing pressure. Corne’s fragmented vendor ecosystem is the opposite trade: more competition on price and case options, but quality and support vary noticeably from shop to shop, and a defective board might mean dealing with a small overseas seller rather than a company with a dedicated support team.
Real-World Use: How Programmers Are Actually Using These Boards
Specs only tell part of the story. Here is how these boards show up in practice for people who write code on them daily.
- A Rust developer built a custom ZMK firmware layer stack on a Corne specifically to reduce reach for syntax-heavy Rust code, documenting the process of shrinking a 42-key layout further to fit their workflow in a build log on leoshimo.com.
- A developer designed a Corne layout around Vim motions, mapping arrow keys to h/j/k/l-adjacent positions and placing Page Up and Page Down on the keys used most during code review, detailed in a practical layout writeup on blog.chaitanyashahare.com.
- A long-time keyboard hobbyist and writer switched to a Corne after building layouts on an ErgoDox EZ, carrying over thumb-key assignments for repeated actions from one board to the other, described on mattgemmell.scot.
- A tech journalist reviewing the ErgoDox EZ for professional use pointed to the split layout’s shoulder-width typing position as the main reason it justified its price, in a hands-on piece for The Next Web.
- A reviewer who spent seven months daily-driving a hall-effect analog board for programming and writing compared its adjustment curve against ortholinear and split boards, noting the retraining period is the single biggest barrier for switchers, according to a long-term test on thetestedhub.com.
The pattern across these accounts is consistent: the initial adjustment period is real, typically measured in weeks rather than days, and most experienced switchers build custom firmware layers specifically around their own repeated coding actions rather than accepting a stock layout.
Wireless, Battery, and Desk Setup Considerations
Neither the ErgoDox EZ nor the Preonic Rev 4 offers a wireless option; both are wired-only via USB, based on their official product listings. For anyone who regularly moves between a laptop and a docking station, or wants to pair a board with a tablet, that is a real limitation for both. Corne is the only board in this comparison with a wireless path, but it is not built in by default. Wireless Corne builds run on ZMK firmware paired with small Bluetooth Low Energy controllers, sold separately or pre-integrated by vendors, like the pre-soldered wireless MX build mentioned earlier. That flexibility comes with the usual DIY wireless trade-offs: battery management and pairing behavior fall on the builder rather than a single manufacturer’s tuned firmware.
For a fixed desk setup where the keyboard never leaves a single machine, the wired-only limitation on the ErgoDox EZ and Preonic Rev 4 barely matters. For anyone who splits time between a desk and a laptop-only setup, it is worth weighing seriously before committing to either.
Who Should Buy the ErgoDox EZ
The ErgoDox EZ makes the most sense for programmers who want the ergonomic benefit of a split, column-staggered layout without touching a soldering iron or a firmware compiler beyond Oryx’s point-and-click interface. Its 76-key layout keeps a dedicated physical key for nearly everything a standard keyboard has, so the learning curve is mostly about adjusting to two separate halves and a thumb cluster, not memorizing new layers. It is the right call for someone who wants this to be a one-time purchase backed by a company with a four-year warranty option, not an ongoing hobby project.
It is also the pick for teams or employers reimbursing a single ergonomic hardware purchase, since a single-vendor invoice from ergodox-ez.com is a far simpler expense report than a pile of PCB, case, switch, and keycap receipts from three different overseas shops. Anyone who has tried to explain a Corne build’s itemized parts list to an accounting department will understand why that matters in practice.
Who Should Buy Corne
Corne fits programmers who are comfortable with, or actively want, a DIY project, and who value the flexibility of choosing their own case, switches, and firmware over a polished out-of-box experience. Its 42-key layout demands more upfront layer configuration, but the payoff is a genuinely tiny footprint and the largest open-source configuration ecosystem of the three boards, backed by 7.6k GitHub stars worth of shared keymaps and case designs. It is also the only board here with a real wireless option. Budget-conscious builders willing to solder can get in for well under $60 in PCB and case costs, while those who want it pre-built can still land below ErgoDox EZ pricing in most configurations.
It also suits anyone who wants to travel light. At roughly a third the footprint of the ErgoDox EZ and without the deep contoured wells of the Preonic Rev 4’s aluminum shell, a pre-built Corne fits into a laptop bag in a way neither other board really manages, which is part of why it shows up so often in remote-work and coworking-space keyboard photos.
Who Should Buy the Preonic Rev 4
The Preonic Rev 4 is the pick for programmers who want the reach-reducing benefit of an ortholinear grid without splitting their hands apart, and who are willing to pre-order a board that will not ship until the end of November 2026. Its 60-key layout keeps a full number row, unlike Corne’s more aggressive layer-dependent approach, while still eliminating the row stagger of a standard board. The CNC aluminum case also makes it the most premium-feeling of the three straight out of the box. It is not for anyone who needs a keyboard immediately, or who wants a split design.
It is worth calling out specifically for programmers coming from a 60% or 65% mechanical keyboard rather than a full-size board, since the transition to ortholinear is a smaller jump than going straight to a split layout. Someone already comfortable with a compact, arrow-key-light keyboard has already made half the adjustment; the Preonic Rev 4 just squares off the stagger on top of that.
5 Use Cases: Matching the Board to the Job
- Full-stack developers who type dense, punctuation-heavy code all day should lean toward the ErgoDox EZ, since its 76-key layout keeps brackets, semicolons, and symbols on dedicated keys instead of buried in layers.
- Backend engineers who work primarily in the terminal and already customize their shell and editor keybindings are the natural audience for Corne, since they are already comfortable configuring software to match their workflow.
- Writers, technical documentation authors, and programmers who split time between code and long-form prose may prefer the Preonic Rev 4’s fuller 60-key layout, which needs fewer layer-shifts for punctuation-heavy writing than Corne.
- Remote workers who move between a home office and a laptop-only setup on the road should prioritize a wireless Corne build, since it is the only board here that supports Bluetooth.
- Anyone recovering from or trying to prevent RSI symptoms who wants a single, well-supported purchase should default to the ErgoDox EZ for its four-year warranty and single-vendor support line, rather than juggling a DIY kit while managing hand pain.
Migration Guide: Moving From a Standard Keyboard to a Split or Ortholinear Board
Switching layouts is less about the hardware and more about retraining muscle memory deliberately. Here is the process that keeps that adjustment period as short as possible, based on the community accounts referenced earlier in this piece.
- Keep your old keyboard connected for the first week. Alternate between boards rather than going cold turkey, especially during a busy sprint.
- Start with the stock layout before customizing anything. Learn where the manufacturer put things before moving keys around; it gives you a baseline to compare changes against.
- Identify your five most-used non-alphabetic keys, brackets, semicolons, arrow keys, and modifiers are common ones for programmers, and make sure they land on your thumb cluster or home row, not a deep layer.
- If you are on Corne or another layer-dependent board, build your base and one symbol layer first. Resist adding five layers on day one; two well-placed layers beat five confusing ones.
- Use Oryx (ErgoDox EZ) or a QMK-based configurator (Corne, Preonic) rather than hand-editing firmware files for your first few iterations, so changes take minutes instead of a full rebuild-and-flash cycle.
- Type real code, not typing tests, during the adjustment period. Typing tests optimize for prose; your actual editor, terminal, and browser dev tools are what you need muscle memory for.
- Expect two to four weeks before your typing speed recovers to its old baseline, based on the adjustment timelines described in the real-world accounts above. Split and ortholinear layouts are not a same-day transition for most people.
- Revisit your layer assignments after two weeks once you know which keys you reach for out of habit versus which ones you actually use, and move them accordingly.
Pros and Cons of Each Board
ErgoDox EZ
- Pro: No soldering, no firmware compiling beyond Oryx’s browser interface.
- Pro: 76 keys means minimal reliance on programmable layers.
- Pro: Warranty extendable to four years.
- Con: Highest baseline price of the three at $295 and up.
- Con: Wired only, no wireless option.
- Con: Single vendor, so no competitive pricing pressure.
Corne (CRKBD V4)
- Pro: Cheapest entry point of the three, with bare PCB kits under $60.
- Pro: Only board here with a wireless option via ZMK.
- Pro: Largest open-source configuration ecosystem, with 7.6k GitHub stars on the design repo alone.
- Con: Requires soldering for the cheapest tiers.
- Con: 42-key layout means a steeper layer-based learning curve.
- Con: Quality and support vary by vendor rather than coming from a single company.
Apos x OLKB Preonic Rev 4
- Pro: Premium CNC aluminum case at a mid-range price.
- Pro: 60-key ortholinear layout keeps a full number row.
- Pro: No soldering required.
- Con: Still on pre-order as of this writing, with shipping not expected until the end of November 2026.
- Con: No split design, so it does not address shoulder-width posture the way the other two boards do.
- Con: Wired only, no wireless option.
The Verdict: Which Keyboard Wins for Programmers in 2026
There is no single winner here, because the three boards are optimized for different tolerances for setup effort. If the goal is the least friction between unboxing and typing comfortably, the ErgoDox EZ remains the safest recommendation: it is pre-assembled, backed by a company with a four-year warranty option, and its 76-key layout means less relearning than either alternative. If budget and customization matter more than convenience, Corne is difficult to beat, with bare kits starting under $60, the only wireless option in this comparison, and a design repository with 7.6k GitHub stars worth of community-tested layouts to start from instead of building blind. The Preonic Rev 4 is the most interesting long-term bet: it is the freshest hardware here, revives a genuinely missed design after a three-year gap, and its aluminum case undercuts the ErgoDox EZ on price while feeling more premium. Its only real drawback in September 2026 is that it is not shippable yet. For programmers who need a keyboard today, that rules it out. For anyone planning a desk refresh for early 2027, it is worth the wait.
Frequently Asked Questions
Is the Planck EZ still available to buy new in 2026?
No. ZSA discontinued the Planck EZ on August 15, 2023, and has not released a replacement. The original OLKB Planck PCB kit is also listed as sold out, with no revision beyond rev 6.1. The closest currently shipping alternative in the ortholinear category is the Apos x OLKB Preonic Rev 4, which opened for pre-order on August 14, 2026.
Do I need to know how to solder to build a Corne keyboard?
Only if you buy a bare PCB kit. Several vendors, including Beekeeb and Ergoboards, sell pre-soldered and pre-built Corne units for programmers who want the open-source design without the assembly step.
What is the difference between QMK and ZMK firmware?
QMK is the older, more widely adopted open-source firmware, with roughly 20.7k GitHub stars and over 44,000 forks, and it powers both the ErgoDox EZ and the Preonic Rev 4. ZMK was built specifically with wireless, Bluetooth Low Energy keyboards in mind and has around 3.5k GitHub stars; it is the more common choice for wireless Corne builds.
Is the ErgoDox EZ worth the price for programmers?
For programmers who want a split ergonomic keyboard without any assembly or firmware compiling, yes. Its price, from roughly $295 to $365 depending on configuration, buys a fully assembled board with an extendable warranty and a browser-based configurator, a meaningfully different experience than sourcing and building a Corne kit yourself.
Can the Preonic Rev 4 be used for both coding and gaming?
Its hot-swap MX-compatible switches and per-key RGB make it usable for light gaming, but it lacks the analog hall-effect switches and rapid-trigger features found on dedicated gaming keyboards, so competitive gamers should look elsewhere.
How long does it take to adjust to a split or ortholinear layout?
Based on documented switcher accounts, most programmers report a two-to-four-week adjustment period before typing speed returns to its previous baseline, with the steepest learning curve on layer-dependent boards like Corne.
Where can I buy a pre-built Corne keyboard instead of a DIY kit?
Community vendors including Beekeeb, PandaKB, and Ergoboards sell pre-soldered Corne units ranging from roughly $178 for wired MX or Choc builds up to around $348 for pre-built wireless configurations.
Does any of these three boards support wireless connectivity?
Only Corne, and only when specifically buying or building a wireless configuration using ZMK firmware and a Bluetooth-capable controller. The ErgoDox EZ and the Preonic Rev 4 are both wired-only via USB.

The practical upshot for programmers weighing whether any of this is worth the money: nobody in these communities is claiming a clinically proven fix, and the accounts referenced throughout this piece are experiential rather than diagnostic. If wrist or shoulder discomfort is already a documented medical issue rather than a general “my hands feel tired by 5pm” complaint, a conversation with an occupational therapist about keyboard and desk setup as a whole, not just which specific board to buy, is a better starting point than picking a keyboard off a comparison article.
Setting Up Your First Custom Layer
Whichever board gets picked, the first real task after unboxing is building a symbol layer, since none of these three keyboards has enough physical keys to place every character a programmer types in a day. On QMK-based boards, that means editing a keymap.c file (or using a graphical tool like Oryx or QMK Configurator, which generate the same underlying structure). A minimal symbol layer accessed by holding a thumb key might look like this:
// Simplified QMK layer example: hold LT(1, KC_SPC) to access the symbol layer
[1] = LAYOUT(
KC_EXLM, KC_AT, KC_HASH, KC_DLR, KC_PERC,
KC_LPRN, KC_RPRN, KC_LBRC, KC_RBRC, KC_PIPE,
KC_MINS, KC_EQL, KC_LCBR, KC_RCBR, KC_BSLS,
_______, _______
)That single layer covers brackets, braces, and the symbols most common in C-family and web languages, accessed without moving hands off the home row. Corne builders typically need two or three layers like this to fully replace a standard keyboard’s dedicated keys, while ErgoDox EZ owners often get away with one, since the base layer already has room for most of the same characters.

Budget-conscious builders willing to solder can get in for well under $60 in PCB and case costs, while those who want it pre-built can still land below ErgoDox EZ pricing in most configurations.
It also suits anyone who wants to travel light. At roughly a third the footprint of the ErgoDox EZ and without the deep contoured wells of the Preonic Rev 4’s aluminum shell, a pre-built Corne fits into a laptop bag in a way neither other board really manages, which is part of why it shows up so often in remote-work and coworking-space keyboard photos.
Who Should Buy the Preonic Rev 4
The Preonic Rev 4 is the pick for programmers who want the reach-reducing benefit of an ortholinear grid without splitting their hands apart, and who are willing to pre-order a board that will not ship until the end of November 2026. Its 60-key layout keeps a full number row, unlike Corne’s more aggressive layer-dependent approach, while still eliminating the row stagger of a standard board. The CNC aluminum case also makes it the most premium-feeling of the three straight out of the box. It is not for anyone who needs a keyboard immediately, or who wants a split design.
It is worth calling out specifically for programmers coming from a 60% or 65% mechanical keyboard rather than a full-size board, since the transition to ortholinear is a smaller jump than going straight to a split layout. Someone already comfortable with a compact, arrow-key-light keyboard has already made half the adjustment; the Preonic Rev 4 just squares off the stagger on top of that.
5 Use Cases: Matching the Board to the Job
- Full-stack developers who type dense, punctuation-heavy code all day should lean toward the ErgoDox EZ, since its 76-key layout keeps brackets, semicolons, and symbols on dedicated keys instead of buried in layers.
- Backend engineers who work primarily in the terminal and already customize their shell and editor keybindings are the natural audience for Corne, since they are already comfortable configuring software to match their workflow.
- Writers, technical documentation authors, and programmers who split time between code and long-form prose may prefer the Preonic Rev 4’s fuller 60-key layout, which needs fewer layer-shifts for punctuation-heavy writing than Corne.
- Remote workers who move between a home office and a laptop-only setup on the road should prioritize a wireless Corne build, since it is the only board here that supports Bluetooth.
- Anyone recovering from or trying to prevent RSI symptoms who wants a single, well-supported purchase should default to the ErgoDox EZ for its four-year warranty and single-vendor support line, rather than juggling a DIY kit while managing hand pain.
Migration Guide: Moving From a Standard Keyboard to a Split or Ortholinear Board
Switching layouts is less about the hardware and more about retraining muscle memory deliberately. Here is the process that keeps that adjustment period as short as possible, based on the community accounts referenced earlier in this piece.
- Keep your old keyboard connected for the first week. Alternate between boards rather than going cold turkey, especially during a busy sprint.
- Start with the stock layout before customizing anything. Learn where the manufacturer put things before moving keys around; it gives you a baseline to compare changes against.
- Identify your five most-used non-alphabetic keys, brackets, semicolons, arrow keys, and modifiers are common ones for programmers, and make sure they land on your thumb cluster or home row, not a deep layer.
- If you are on Corne or another layer-dependent board, build your base and one symbol layer first. Resist adding five layers on day one; two well-placed layers beat five confusing ones.
- Use Oryx (ErgoDox EZ) or a QMK-based configurator (Corne, Preonic) rather than hand-editing firmware files for your first few iterations, so changes take minutes instead of a full rebuild-and-flash cycle.
- Type real code, not typing tests, during the adjustment period. Typing tests optimize for prose; your actual editor, terminal, and browser dev tools are what you need muscle memory for.
- Expect two to four weeks before your typing speed recovers to its old baseline, based on the adjustment timelines described in the real-world accounts above. Split and ortholinear layouts are not a same-day transition for most people.
- Revisit your layer assignments after two weeks once you know which keys you reach for out of habit versus which ones you actually use, and move them accordingly.
Pros and Cons of Each Board
ErgoDox EZ
- Pro: No soldering, no firmware compiling beyond Oryx’s browser interface.

- Pro: 60-key ortholinear layout keeps a full number row.
- Pro: No soldering required.
- Con: Still on pre-order as of this writing, with shipping not expected until the end of November 2026.
- Con: No split design, so it does not address shoulder-width posture the way the other two boards do.
- Con: Wired only, no wireless option.
The Verdict: Which Keyboard Wins for Programmers in 2026
There is no single winner here, because the three boards are optimized for different tolerances for setup effort. If the goal is the least friction between unboxing and typing comfortably, the ErgoDox EZ remains the safest recommendation: it is pre-assembled, backed by a company with a four-year warranty option, and its 76-key layout means less relearning than either alternative. If budget and customization matter more than convenience, Corne is difficult to beat, with bare kits starting under $60, the only wireless option in this comparison, and a design repository with 7.6k GitHub stars worth of community-tested layouts to start from instead of building blind. The Preonic Rev 4 is the most interesting long-term bet: it is the freshest hardware here, revives a genuinely missed design after a three-year gap, and its aluminum case undercuts the ErgoDox EZ on price while feeling more premium. Its only real drawback in September 2026 is that it is not shippable yet. For programmers who need a keyboard today, that rules it out. For anyone planning a desk refresh for early 2027, it is worth the wait.
Frequently Asked Questions
Is the Planck EZ still available to buy new in 2026?
No. ZSA discontinued the Planck EZ on August 15, 2023, and has not released a replacement. The original OLKB Planck PCB kit is also listed as sold out, with no revision beyond rev 6.1. The closest currently shipping alternative in the ortholinear category is the Apos x OLKB Preonic Rev 4, which opened for pre-order on August 14, 2026.
Do I need to know how to solder to build a Corne keyboard?
Only if you buy a bare PCB kit. Several vendors, including Beekeeb and Ergoboards, sell pre-soldered and pre-built Corne units for programmers who want the open-source design without the assembly step.
What is the difference between QMK and ZMK firmware?
QMK is the older, more widely adopted open-source firmware, with roughly 20.7k GitHub stars and over 44,000 forks, and it powers both the ErgoDox EZ and the Preonic Rev 4. ZMK was built specifically with wireless, Bluetooth Low Energy keyboards in mind and has around 3.5k GitHub stars; it is the more common choice for wireless Corne builds.
Is the ErgoDox EZ worth the price for programmers?
For programmers who want a split ergonomic keyboard without any assembly or firmware compiling, yes. Its price, from roughly $295 to $365 depending on configuration, buys a fully assembled board with an extendable warranty and a browser-based configurator, a meaningfully different experience than sourcing and building a Corne kit yourself.
Can the Preonic Rev 4 be used for both coding and gaming?
Its hot-swap MX-compatible switches and per-key RGB make it usable for light gaming, but it lacks the analog hall-effect switches and rapid-trigger features found on dedicated gaming keyboards, so competitive gamers should look elsewhere.
How long does it take to adjust to a split or ortholinear layout?
Based on documented switcher accounts, most programmers report a two-to-four-week adjustment period before typing speed returns to its previous baseline, with the steepest learning curve on layer-dependent boards like Corne.
Where can I buy a pre-built Corne keyboard instead of a DIY kit?
Community vendors including Beekeeb, PandaKB, and Ergoboards sell pre-soldered Corne units ranging from roughly $178 for wired MX or Choc builds up to around $348 for pre-built wireless configurations.
Does any of these three boards support wireless connectivity?
Only Corne, and only when specifically buying or building a wireless configuration using ZMK firmware and a Bluetooth-capable controller. The ErgoDox EZ and the Preonic Rev 4 are both wired-only via USB.

The mainstream keyboard aisle spent 2026 obsessing over Hall-effect switches and 8,000Hz polling rates built for gaming. Meanwhile, a quieter argument has been playing out in developer Slack channels and GitHub issue threads: whether a split, column-staggered board or a flat ortholinear grid does more for someone who types eight hours a day for a living. Three boards keep coming up in that argument. The ErgoDox EZ is the assembled, no-soldering split that made ergonomic keyboards a mainstream purchase instead of a hobbyist project. Corne (CRKBD) is the open-source 42-key split that a huge slice of the custom keyboard community has settled on, currently sitting at version 4. And the Apos x OLKB Preonic Rev 4 is the board that, as of September 11, 2026, is barely a month old, reviving a design that Drop and ZSA had both walked away from.
This comparison pulls exact 2026 pricing, GitHub star counts, firmware details, and case specs for all three boards, plus the story of why one of their closest relatives, the Planck EZ, is not on this list at all anymore. If you write code for a living and your wrists have started sending you complaints, here is what actually separates these three boards, what they cost right now, and which one fits your setup.
Why Programmers Are Rethinking Keyboard Layout in 2026
The pitch for split and ortholinear keyboards has not changed much in a decade: row-staggered typewriter layouts were designed around mechanical linkages, not hands, and reaching across a QWERTY grid all day puts recurring strain on the wrists and shoulders. What has changed is who is willing to try the fix. Remote and hybrid work pushed more programmers into buying their own desk hardware instead of using whatever IT handed out, and a wave of hot-swappable, pre-assembled boards removed the soldering iron as a barrier to entry.
The three boards in this comparison represent three different bets on how far to take that idea. The ErgoDox EZ keeps a recognizable QWERTY-adjacent layout split across two halves with a large thumb cluster added on. Corne strips the key count down to 42 and asks you to lean on programmable layers instead of dedicated punctuation and number keys. The Preonic Rev 4 skips the split entirely and instead flattens a 60-key grid into strict rows and columns, betting that ortholinear alignment alone solves most of the reach problem. None of these are gaming keyboards first, and none of them show up in the Hall-effect rapid-trigger conversation dominating hardware coverage this year. They are built for people who spend their day in a terminal, an IDE, or a browser tab full of documentation.
Meet the Three Boards, and the One That Disappeared
Before comparing specs, it is worth explaining why the lineup looks the way it does. For years, the natural three-way comparison in this category would have included the Planck EZ, ZSA’s 40% ortholinear board. That comparison is no longer possible to make honestly, because ZSA discontinued the Planck EZ on August 15, 2023, and never shipped a replacement. The original OLKB Planck PCB kit, sold independently of ZSA’s assembled version, is also listed as sold out with no revision beyond rev 6.1, according to OLKB’s own product page.
That left a gap in the “unibody ortholinear” category for three years. It only closed on August 14, 2026, when audio and peripherals retailer Apos partnered with OLKB to relaunch Jack Humbert’s original Preonic design as the Preonic Rev 4, according to Try Ortho Keys’ OLKB buying guide. That is why this comparison swaps in the Preonic Rev 4 instead of the discontinued Planck EZ: it is the current, purchasable, actively shipping representative of that design philosophy, and rule one of picking hardware in September 2026 is not recommending something you cannot actually buy new.
The ErgoDox EZ, by contrast, has stayed in continuous production since ZSA launched it, and Corne has iterated openly through community revisions up to the current V4 hardware, which added a Raspberry Pi RP2040 microcontroller and support for either MX or Choc low-profile switches, per KBD.news’ Corne V4 specification writeup.
Layout and Ergonomics: Column-Stagger vs Split Grid vs Unibody Ortholinear
The ErgoDox EZ uses a column-staggered split layout: each half holds a roughly 5×7 grid where columns, not rows, are offset to match finger length, plus a deep, contoured thumb cluster with several dedicated keys. The full board totals 76 keys across both halves, according to the spec table published by Try Ortho Keys’ split keyboard comparison. That key count means most punctuation, number, and modifier keys still get a physical position, so the learning curve is closer to “get used to two separate halves” than “relearn where every character lives.”
Corne takes the opposite approach. The standard V4 configuration uses a 3×6 column-staggered grid per hand plus three thumb keys, for 42 keys total, though vendors also sell 3×5 variants with a snap-off outer column, per KBD.news. With roughly half the keys of a standard board, Corne users lean heavily on programmable layers accessed through the thumb cluster to reach numbers, symbols, and function keys. It is a bigger adjustment, but it also means less finger travel once the layout is memorized.
The Preonic Rev 4 is neither split nor column-staggered. It is a single, unibody board with 60 keys arranged in a strict 5-row by 12-column ortholinear grid, described by Apos as a rebuild of Jack Humbert’s original 5×12 ortholinear board, according to the official Apos product page. Every key lines up in a perfect column instead of the diagonal stagger of a traditional keyboard, which removes the lateral finger reach that row-staggered typing requires, without asking you to physically split your hands apart.

Switches, Hot-Swap Sockets, and Build Quality
All three boards ship as hot-swap, meaning switches can be pulled and replaced without a soldering iron on the finished boards. The ErgoDox EZ supports MX-style mechanical switches, and ZSA’s build process has historically offered Cherry, Kailh Box, and Gateron options depending on stock at order time. Corne’s V4 hardware branches in two directions depending on which PCB gets ordered: a standard MX version compatible with full-size Cherry-style switches, and a Choc version built for Kailh’s low-profile Choc switches, which trades key travel for a noticeably slimmer case. The Preonic Rev 4 ships with a ground-up 4-layer hot-swap PCB and offers pre-installed switch options including Gateron Yellow KS-3 linear and TTC Silent Bluish White V2 tactile switches, according to Try Mech Keys’ Apos deals coverage.
Case construction is where the three boards diverge the most. The ErgoDox EZ uses a molded plastic shell with adjustable tenting legs and optional wrist rests, the formula ZSA has used since launch. Corne’s case options depend entirely on which vendor supplies the kit. Beekeeb, for example, sells a carbon-fiber-top-and-acrylic-bottom case kit alongside its PCBs, while many builders in the community 3D-print their own cases from open-source files. The Preonic Rev 4 is the outlier here: it ships in a CNC-machined aluminum case available in black, silver, or yellow finishes, giving it a noticeably heavier, more premium feel than either of the other two boards straight out of the box, confirmed by both Apos and Try Ortho Keys’ Preonic Rev 4 launch coverage.
Keycaps, Typing Feel, and Noise for Open Offices and Video Calls
Switch choice affects sound and feel more than almost any other spec on this list, and it matters more for programmers than most buyers realize, since a big share of coding now happens on video calls. The ErgoDox EZ’s default Cherry and Kailh Box options span linear, tactile, and clicky profiles, so the noise level is entirely a function of which switch a buyer selects at checkout rather than anything fixed about the board itself. Corne kits follow the same logic but go further: because the PCB is hot-swap and sold separately from any pre-installed switch, builders routinely mix in dedicated silent linear switches specifically to avoid being “that person” clacking away on a stand-up call. The Preonic Rev 4’s pre-installed options lean toward the quieter end by default, with the Gateron Yellow KS-3 linear switch and the TTC Silent Bluish White V2 tactile switch both marketed around reduced noise output rather than a loud, clicky feel.
Keycap profile is the other variable that changes typing feel without changing the underlying switch. ErgoDox EZ ships with a sculpted profile designed around its column-staggered layout, so each row is angled slightly differently to match natural finger curl. Corne kits are typically sold with flat, uniform-height DSA or lightly sculpted DCS-style caps, which suit an ortholinear grid where every key sits in the same plane. The Preonic Rev 4 follows the same flat-profile logic as Corne, since ortholinear boards generally use uniform caps rather than the row-specific sculpting found on staggered keyboards. None of these differences show up in a spec sheet, but they are the first thing a programmer notices in the first hour of typing on any of these three boards. Readers who want a deeper breakdown of how switch type changes both sound and actuation feel across the wider market, not just on these three DIY-adjacent boards, can see our full tactile vs linear vs clicky switch comparison.
RSI and Ergonomics: What the Research Actually Says
It is worth being direct about a gap in the data here: there are no peer-reviewed clinical studies isolating the repetitive strain injury outcomes of the ErgoDox EZ, Corne, or Preonic Rev 4 specifically. What exists instead is a large body of general occupational ergonomics guidance, which consistently flags two mechanisms that split and ortholinear keyboards are designed to reduce: ulnar deviation (bending the wrist sideways to reach across a standard keyboard) and forearm pronation (rotating the forearm inward to type on a flat surface). A split board like the ErgoDox EZ or Corne lets a typist position each half at shoulder width, which addresses the deviation problem directly. An ortholinear board like the Preonic Rev 4 does not change hand position, but it does remove the diagonal reach between rows that a staggered layout requires, which is a smaller but still real reduction in finger travel.
The practical upshot for programmers weighing whether any of this is worth the money: nobody in these communities is claiming a clinically proven fix, and the accounts referenced throughout this piece are experiential rather than diagnostic. If wrist or shoulder discomfort is already a documented medical issue rather than a general “my hands feel tired by 5pm” complaint, a conversation with an occupational therapist about keyboard and desk setup as a whole, not just which specific board to buy, is a better starting point than picking a keyboard off a comparison article.
Setting Up Your First Custom Layer
Whichever board gets picked, the first real task after unboxing is building a symbol layer, since none of these three keyboards has enough physical keys to place every character a programmer types in a day. On QMK-based boards, that means editing a keymap.c file (or using a graphical tool like Oryx or QMK Configurator, which generate the same underlying structure). A minimal symbol layer accessed by holding a thumb key might look like this:
// Simplified QMK layer example: hold LT(1, KC_SPC) to access the symbol layer
[1] = LAYOUT(
KC_EXLM, KC_AT, KC_HASH, KC_DLR, KC_PERC,
KC_LPRN, KC_RPRN, KC_LBRC, KC_RBRC, KC_PIPE,
KC_MINS, KC_EQL, KC_LCBR, KC_RCBR, KC_BSLS,
_______, _______
)That single layer covers brackets, braces, and the symbols most common in C-family and web languages, accessed without moving hands off the home row. Corne builders typically need two or three layers like this to fully replace a standard keyboard’s dedicated keys, while ErgoDox EZ owners often get away with one, since the base layer already has room for most of the same characters. For a full walkthrough of flashing QMK or VIA firmware onto a hot-swap board step by step, see our guide to flashing QMK/VIA firmware, and for a broader look at how QMK, VIA, and ZMK differ as firmware platforms beyond just these three boards, see our QMK vs VIA vs ZMK comparison.
How These Compare to Mainstream Ergonomic Keyboards
ErgoDox EZ, Corne, and the Preonic Rev 4 are not the only ergonomic options a programmer will run into while shopping. Boards like the Kinesis Advantage360 Pro, the ZSA Voyager, and the MoErgo Glove80 occupy a more turnkey, higher-price tier of the same general idea, typically with deeper contoured key wells, wireless support out of the box, and a single polished configurator. Mainstream mechanical boards from Keychron and similar brands, meanwhile, keep a standard row-staggered unibody layout but add hot-swap sockets and better switches than a typical office keyboard, without asking a buyer to relearn hand position at all. For a broader roundup of that wider category, including boards outside the DIY and ortholinear niche covered here, see our roundup of mechanical keyboards for programmers.
What separates the three boards in this comparison from that wider field is price and philosophy rather than raw ergonomic benefit. Corne in particular is priced closer to a hobby project than a peripheral purchase, and building one from a bare PCB is itself part of the appeal for a meaningful slice of its audience. Programmers who want the DIY experience to extend beyond just this comparison, building an entirely custom board from scratch rather than a kit built around an existing open-source PCB, can find the general process in our guide to building a custom mechanical keyboard.
Firmware Face-Off: QMK, ZMK, and the Oryx Configurator
Firmware is arguably a bigger differentiator between these boards than the physical layout, because it decides how much of your workflow you can reprogram. The ErgoDox EZ runs on QMK, but ZSA wraps it in Oryx, a browser-based configurator that compiles firmware in the cloud so nobody has to touch a command line. That convenience costs some flexibility: you are working within ZSA’s maintained fork of QMK rather than the bleeding edge of the open-source project.
Corne is where the open-source firmware ecosystem is most visible. Builders can flash either QMK or ZMK, and the community leans toward ZMK specifically for wireless builds, since it was designed from the ground up around Bluetooth Low Energy. The QMK project sits at roughly 20.7k GitHub stars and more than 44,000 forks as of early September 2026, according to the qmk_firmware repository, while ZMK’s repository has around 3.5k stars, per the zmk repository on GitHub. Corne’s own hardware design repository, crkbd, has separately accumulated 7.6k stars and 1.1k forks, tracked by SrcLog’s open-source metadata tracker. That is a large, active base of shared keymaps and layout configurations to draw from instead of starting from a blank file. The Preonic Rev 4 runs QMK directly on its onboard RP2040 chip, giving it the same underlying firmware as the ErgoDox EZ, without the Oryx wrapper. That means more manual setup, but also fewer platform restrictions for anyone who wants to hand-edit a keymap.
For programmers who already spend their day in a terminal, this is not a small distinction. Custom firmware and RP2040-class microcontrollers are part of a much broader hardware story this year, running alongside the same category of low-power chips showing up across the wider AI PC and edge computing hardware market covered in our 2026 AI chips coverage.
Pricing Breakdown: $30 DIY Kits to $365 Pre-Built Boards
Price is where this comparison gets genuinely wide. Here is what each board actually costs across its available configurations as of September 2026.
| Tier | ErgoDox EZ | Corne (CRKBD V4) | Apos x OLKB Preonic Rev 4 |
|---|---|---|---|
| Entry / bare kit | N/A, sold assembled only | ~$30–$48 (bare MX hotswap PCB set, Beekeeb) | $150 (barebones case + PCB + plate) |
| Mid configuration | ~$295–$325 | ~$178 (pre-soldered Choc low-profile board) | $170–$185 (keycaps or switches added) |
| Fully loaded | ~$365 (Glow, full extras) | ~$227–$348 (pre-soldered wireless MX build) | $205 (full keycaps and switches) |
| Assembly needed to reach that price | None | Soldering for bare PCB tiers only | None |
Sources: Try Ortho Keys, Beekeeb’s Corne storefront, and Try Ortho Keys’ OLKB buying guide.
That spread means the gap between the cheapest usable Corne kit and the most expensive ErgoDox EZ configuration runs as high as $335. Even comparing pre-built, ready-to-type options rather than bare PCBs, a pre-soldered Corne still lands around $178 to $348, meaning it can be either the cheapest or the most expensive of the three depending on which wireless or case configuration is chosen. The New York Times’ Wirecutter has flagged the ErgoDox EZ’s pricing directly for years, noting it “starts at $350, considerably more than most other keyboards we recommend,” in its ergonomic keyboard guide, though current 2026 retail listings show it available from roughly $295 depending on configuration.
Benchmarks: Community Size, Ecosystem Support, and Build Data
Mechanical keyboards for programmers do not have frame-rate benchmarks, but they do have measurable proxies for how supported and mature a board’s ecosystem is: GitHub activity, vendor availability, and how long a design has stayed in active production.
| Metric | ErgoDox EZ | Corne (CRKBD) | Preonic Rev 4 | Source |
|---|---|---|---|---|
| Firmware repo GitHub stars | 20.7k (QMK, shared) | 7.6k (crkbd design repo) plus access to QMK/ZMK | 20.7k (QMK, shared) | GitHub / SrcLog |
| Years in continuous production | 10+ years, no discontinuation | Actively revised through 4 hardware generations | Relaunched Aug. 2026 after a 3-year gap | ZSA, KBD.news, Try Ortho Keys |
| Warranty length | Up to 4 years (extendable) | Vendor-dependent, often none on bare kits | Standard retail warranty via Apos | ergodox-ez.com |
| Vendor / purchase channels | 1 (ZSA direct) | 4+ community vendors (Beekeeb, PandaKB, Ergoboards, and others) | 1 (Apos direct) | Beekeeb, Ergoboards, Apos |
The single-vendor model for the ErgoDox EZ and the Preonic Rev 4 means consistent quality control and one place to go for support, but no competitive pricing pressure. Corne’s fragmented vendor ecosystem is the opposite trade: more competition on price and case options, but quality and support vary noticeably from shop to shop, and a defective board might mean dealing with a small overseas seller rather than a company with a dedicated support team.
Real-World Use: How Programmers Are Actually Using These Boards
Specs only tell part of the story. Here is how these boards show up in practice for people who write code on them daily.
- A Rust developer built a custom ZMK firmware layer stack on a Corne specifically to reduce reach for syntax-heavy Rust code, documenting the process of shrinking a 42-key layout further to fit their workflow in a build log on leoshimo.com.
- A developer designed a Corne layout around Vim motions, mapping arrow keys to h/j/k/l-adjacent positions and placing Page Up and Page Down on the keys used most during code review, detailed in a practical layout writeup on blog.chaitanyashahare.com.
- A long-time keyboard hobbyist and writer switched to a Corne after building layouts on an ErgoDox EZ, carrying over thumb-key assignments for repeated actions from one board to the other, described on mattgemmell.scot.
- A tech journalist reviewing the ErgoDox EZ for professional use pointed to the split layout’s shoulder-width typing position as the main reason it justified its price, in a hands-on piece for The Next Web.
- A reviewer who spent seven months daily-driving a hall-effect analog board for programming and writing compared its adjustment curve against ortholinear and split boards, noting the retraining period is the single biggest barrier for switchers, according to a long-term test on thetestedhub.com.
The pattern across these accounts is consistent: the initial adjustment period is real, typically measured in weeks rather than days, and most experienced switchers build custom firmware layers specifically around their own repeated coding actions rather than accepting a stock layout.
Wireless, Battery, and Desk Setup Considerations
Neither the ErgoDox EZ nor the Preonic Rev 4 offers a wireless option; both are wired-only via USB, based on their official product listings. For anyone who regularly moves between a laptop and a docking station, or wants to pair a board with a tablet, that is a real limitation for both. Corne is the only board in this comparison with a wireless path, but it is not built in by default. Wireless Corne builds run on ZMK firmware paired with small Bluetooth Low Energy controllers, sold separately or pre-integrated by vendors, like the pre-soldered wireless MX build mentioned earlier. That flexibility comes with the usual DIY wireless trade-offs: battery management and pairing behavior fall on the builder rather than a single manufacturer’s tuned firmware.
For a fixed desk setup where the keyboard never leaves a single machine, the wired-only limitation on the ErgoDox EZ and Preonic Rev 4 barely matters. For anyone who splits time between a desk and a laptop-only setup, it is worth weighing seriously before committing to either.
Who Should Buy the ErgoDox EZ
The ErgoDox EZ makes the most sense for programmers who want the ergonomic benefit of a split, column-staggered layout without touching a soldering iron or a firmware compiler beyond Oryx’s point-and-click interface. Its 76-key layout keeps a dedicated physical key for nearly everything a standard keyboard has, so the learning curve is mostly about adjusting to two separate halves and a thumb cluster, not memorizing new layers. It is the right call for someone who wants this to be a one-time purchase backed by a company with a four-year warranty option, not an ongoing hobby project.
It is also the pick for teams or employers reimbursing a single ergonomic hardware purchase, since a single-vendor invoice from ergodox-ez.com is a far simpler expense report than a pile of PCB, case, switch, and keycap receipts from three different overseas shops. Anyone who has tried to explain a Corne build’s itemized parts list to an accounting department will understand why that matters in practice.
Who Should Buy Corne
Corne fits programmers who are comfortable with, or actively want, a DIY project, and who value the flexibility of choosing their own case, switches, and firmware over a polished out-of-box experience. Its 42-key layout demands more upfront layer configuration, but the payoff is a genuinely tiny footprint and the largest open-source configuration ecosystem of the three boards, backed by 7.6k GitHub stars worth of shared keymaps and case designs. It is also the only board here with a real wireless option. Budget-conscious builders willing to solder can get in for well under $60 in PCB and case costs, while those who want it pre-built can still land below ErgoDox EZ pricing in most configurations.
It also suits anyone who wants to travel light. At roughly a third the footprint of the ErgoDox EZ and without the deep contoured wells of the Preonic Rev 4’s aluminum shell, a pre-built Corne fits into a laptop bag in a way neither other board really manages, which is part of why it shows up so often in remote-work and coworking-space keyboard photos.
Who Should Buy the Preonic Rev 4
The Preonic Rev 4 is the pick for programmers who want the reach-reducing benefit of an ortholinear grid without splitting their hands apart, and who are willing to pre-order a board that will not ship until the end of November 2026. Its 60-key layout keeps a full number row, unlike Corne’s more aggressive layer-dependent approach, while still eliminating the row stagger of a standard board. The CNC aluminum case also makes it the most premium-feeling of the three straight out of the box. It is not for anyone who needs a keyboard immediately, or who wants a split design.
It is worth calling out specifically for programmers coming from a 60% or 65% mechanical keyboard rather than a full-size board, since the transition to ortholinear is a smaller jump than going straight to a split layout. Someone already comfortable with a compact, arrow-key-light keyboard has already made half the adjustment; the Preonic Rev 4 just squares off the stagger on top of that.
5 Use Cases: Matching the Board to the Job
- Full-stack developers who type dense, punctuation-heavy code all day should lean toward the ErgoDox EZ, since its 76-key layout keeps brackets, semicolons, and symbols on dedicated keys instead of buried in layers.
- Backend engineers who work primarily in the terminal and already customize their shell and editor keybindings are the natural audience for Corne, since they are already comfortable configuring software to match their workflow.
- Writers, technical documentation authors, and programmers who split time between code and long-form prose may prefer the Preonic Rev 4’s fuller 60-key layout, which needs fewer layer-shifts for punctuation-heavy writing than Corne.
- Remote workers who move between a home office and a laptop-only setup on the road should prioritize a wireless Corne build, since it is the only board here that supports Bluetooth.
- Anyone recovering from or trying to prevent RSI symptoms who wants a single, well-supported purchase should default to the ErgoDox EZ for its four-year warranty and single-vendor support line, rather than juggling a DIY kit while managing hand pain.
Migration Guide: Moving From a Standard Keyboard to a Split or Ortholinear Board
Switching layouts is less about the hardware and more about retraining muscle memory deliberately. Here is the process that keeps that adjustment period as short as possible, based on the community accounts referenced earlier in this piece.
- Keep your old keyboard connected for the first week. Alternate between boards rather than going cold turkey, especially during a busy sprint.
- Start with the stock layout before customizing anything. Learn where the manufacturer put things before moving keys around; it gives you a baseline to compare changes against.
- Identify your five most-used non-alphabetic keys, brackets, semicolons, arrow keys, and modifiers are common ones for programmers, and make sure they land on your thumb cluster or home row, not a deep layer.
- If you are on Corne or another layer-dependent board, build your base and one symbol layer first. Resist adding five layers on day one; two well-placed layers beat five confusing ones.
- Use Oryx (ErgoDox EZ) or a QMK-based configurator (Corne, Preonic) rather than hand-editing firmware files for your first few iterations, so changes take minutes instead of a full rebuild-and-flash cycle.
- Type real code, not typing tests, during the adjustment period. Typing tests optimize for prose; your actual editor, terminal, and browser dev tools are what you need muscle memory for.
- Expect two to four weeks before your typing speed recovers to its old baseline, based on the adjustment timelines described in the real-world accounts above. Split and ortholinear layouts are not a same-day transition for most people.
- Revisit your layer assignments after two weeks once you know which keys you reach for out of habit versus which ones you actually use, and move them accordingly.
Pros and Cons of Each Board
ErgoDox EZ
- Pro: No soldering, no firmware compiling beyond Oryx’s browser interface.

- Pro: Premium CNC aluminum case at a mid-range price.
- Pro: 60-key ortholinear layout keeps a full number row.
- Pro: No soldering required.
- Con: Still on pre-order as of this writing, with shipping not expected until the end of November 2026.
- Con: No split design, so it does not address shoulder-width posture the way the other two boards do.
- Con: Wired only, no wireless option.
The Verdict: Which Keyboard Wins for Programmers in 2026
There is no single winner here, because the three boards are optimized for different tolerances for setup effort. If the goal is the least friction between unboxing and typing comfortably, the ErgoDox EZ remains the safest recommendation: it is pre-assembled, backed by a company with a four-year warranty option, and its 76-key layout means less relearning than either alternative. If budget and customization matter more than convenience, Corne is difficult to beat, with bare kits starting under $60, the only wireless option in this comparison, and a design repository with 7.6k GitHub stars worth of community-tested layouts to start from instead of building blind. The Preonic Rev 4 is the most interesting long-term bet: it is the freshest hardware here, revives a genuinely missed design after a three-year gap, and its aluminum case undercuts the ErgoDox EZ on price while feeling more premium. Its only real drawback in September 2026 is that it is not shippable yet. For programmers who need a keyboard today, that rules it out. For anyone planning a desk refresh for early 2027, it is worth the wait.
Frequently Asked Questions
Is the Planck EZ still available to buy new in 2026?
No. ZSA discontinued the Planck EZ on August 15, 2023, and has not released a replacement. The original OLKB Planck PCB kit is also listed as sold out, with no revision beyond rev 6.1. The closest currently shipping alternative in the ortholinear category is the Apos x OLKB Preonic Rev 4, which opened for pre-order on August 14, 2026.
Do I need to know how to solder to build a Corne keyboard?
Only if you buy a bare PCB kit. Several vendors, including Beekeeb and Ergoboards, sell pre-soldered and pre-built Corne units for programmers who want the open-source design without the assembly step.
What is the difference between QMK and ZMK firmware?
QMK is the older, more widely adopted open-source firmware, with roughly 20.7k GitHub stars and over 44,000 forks, and it powers both the ErgoDox EZ and the Preonic Rev 4. ZMK was built specifically with wireless, Bluetooth Low Energy keyboards in mind and has around 3.5k GitHub stars; it is the more common choice for wireless Corne builds.
Is the ErgoDox EZ worth the price for programmers?
For programmers who want a split ergonomic keyboard without any assembly or firmware compiling, yes. Its price, from roughly $295 to $365 depending on configuration, buys a fully assembled board with an extendable warranty and a browser-based configurator, a meaningfully different experience than sourcing and building a Corne kit yourself.
Can the Preonic Rev 4 be used for both coding and gaming?
Its hot-swap MX-compatible switches and per-key RGB make it usable for light gaming, but it lacks the analog hall-effect switches and rapid-trigger features found on dedicated gaming keyboards, so competitive gamers should look elsewhere.
How long does it take to adjust to a split or ortholinear layout?
Based on documented switcher accounts, most programmers report a two-to-four-week adjustment period before typing speed returns to its previous baseline, with the steepest learning curve on layer-dependent boards like Corne.
Where can I buy a pre-built Corne keyboard instead of a DIY kit?
Community vendors including Beekeeb, PandaKB, and Ergoboards sell pre-soldered Corne units ranging from roughly $178 for wired MX or Choc builds up to around $348 for pre-built wireless configurations.
Does any of these three boards support wireless connectivity?
Only Corne, and only when specifically buying or building a wireless configuration using ZMK firmware and a Bluetooth-capable controller. The ErgoDox EZ and the Preonic Rev 4 are both wired-only via USB.
