QMK runs on a diverse range of keyboards. Some of these keyboards are well maintained and see constant community contributions, while others are part of the repository for historical reasons.
What makes OLKB keyboards shine is a combo of lean aesthetics, compact size, and killer tactile feel. These are available through [olkb.com](http://olkb.com) as well as through [Massdrop](http://massdrop.com) from time to time, as easy to assemble kits.
* [Planck](/keyboards/planck/) — A 40% DIY powerhouse of customizability and modification capability. It's a lean, mean, typing machine.
* [Preonic](/keyboards/preonic/) — Like the Planck, but bigger. 50%.
* [Atomic](/keyboards/atomic/) — Imagine the size of the Planck. Now imagine the size of the Preonic. Now imagine _bigger_. That is the Atomic. A 60% keyboard.
[ZSA Technology Labs](https://zsa.io) maintains its own [fork of QMK](https://github.com/zsa/qmk_firmware) which feeds its [configurator](https://configure.zsa.io), for stability and legal purposes. The ZSA boards are:
* [Moonlander Mark I](/keyboards/moonlander/) — A next-gen split, ergonomic keyboard with an active left side, USB type C, integrated wrist rest, and a thumb cluster that can move.
* [ErgoDox EZ](/keyboards/ergodox_ez/) — A powerful split mechanical keyboard.
* [Planck EZ](/keyboards/planck/ez) — A 40% DIY powerhouse of customizability and modification capability. It's a lean, mean, typing machine, which ships fully assembled with a two-year warranty.
