QMK (Quantum Mechanical Keyboard) is open-source firmware for custom keyboards and other input devices, supporting Atmel AVR and ARM USB microcontrollers. It powers over 3000 keyboards with fully customizable keymaps, layers, and features, configurable via a graphical configurator or directly in C.
Use cases
- flash custom firmware onto a mechanical keyboard
- remap keys and create custom keymaps for my keyboard
- configure layers and macros on an ErgoDox EZ or Planck
- build firmware for a handwired or custom keyboard
- customize RGB lighting and encoder behavior on a keyboard
- support for mice and MIDI input devices
When to choose
- you want deep, code-level customization of keyboard behavior
- your keyboard is one of the 3000+ supported boards or you're building your own
- you need layers, macros, tap-hold, or advanced features beyond stock firmware
When to avoid
- you want a simple GUI-only remapping tool with no compilation (consider VIA/Remap with QMK-based boards)
- your keyboard only supports proprietary manufacturer firmware
- you're not comfortable flashing firmware, which carries a small risk of bricking
