Runs Completely Locally & Privately
KludgeKnight runs entirely in your browser. All key remapping and configuration happens locally on your device. Your keyboard settings are saved only in your browser's local storage and never leave your computer.
We use Google Analytics to understand basic site traffic (page views, visitor counts), but no keyboard configuration data or personal information is collected.

Lighting Controls
Lightly tested on RK F68, should work on most devices

Important Limitations
Cannot Read Settings from Keyboard
RK firmware does not allow reading of settings. The app can only write new mappings.
All Keys Written at Once
When you change a single key mapping, all key mappings are written to the keyboard.
Browser LocalStorage Only
Mappings cannot be stored on the keyboard itself. Your custom mappings are saved in browser localStorage, so they will only persist on the same browser on the same computer. Clearing browser history will delete saved mappings.
Supported Keyboards
KludgeKnight supports 195 Royal Kludge keyboard models. Click on any keyboard to view its layout image.
