Chrysalis is a graphical configurator for Kaleidoscope-powered keyboards. While still heavily under development, it's at a stage where it is already usable for a number of tasks. To try it, you don't even need to flash Kaleidoscope beforehand, Chrysalis can do that for you, as it ships with reasonable default firmware for each supported board.

The primary purpose of the application is to allow one to configure their keyboard without having to compile or flash firmware, by storing the configuration on the keyboard itself, in EEPROM. There are no external tools required, just Chrysalis itself.


  • Layout editor to edit the keymap on-the-fly, with the ability to copy one layer to another, and to set a default one.
  • Colormap editor to edit the per-key LED colormap on boards that support it.
  • Firmware upgrade to upload either the default, Chrysalis-enabled firmware that ships with the application, or a custom one.

Supported Hardware

Chrysalis supports the Keyboardio Model01, the ErgoDox EZ (and any other keyboard wired like the original ErgoDox), the Atreus, and has perliminary support for Dygma's Raise. Support for more keyboards are under development.

Supported operating systems

Chrysalis is primarily developed under Linux, but we target all three major operating systems, and test our releases on Windows and OSX too. That said, our testing is done on Ubuntu 18.04 LTS, Windows 10, and OSX Mojave.

The protocol Chrysalis uses to communicate with the keyboard requires USB serial support, which is known to be problematic on Windows prior to Windows 10.

Reporting issues

Chrysalis is alpha quality software. There will be bugs, missing features and non-obvious things. Reporting any and all of these help us make the software better, please feel free to open issues liberally!
