Unofficial · open source · runs in your browser

Remap and relight your Royal Kludge keyboard

Map keys and modifier chords, paint per-key colors, and review every change before anything reaches the keyboard.

Desktop Chrome, Edge or Opera · USB cable · Mac, Windows, Linux

Verified on hardware: RK61 (258A:0055) over USB. Other listed models are experimental.

RK61 · WASD palette

What it does

Remap keys and chords.

Map a key to another key, a media function, or a chord such as ⌘ Command + C, with left and right modifiers kept separate.

Paint per-key colors.

Set mode, brightness, speed and sleep, then paint single keys or start from a built-in palette on models with an established custom mode (currently the RK61 0055).

Nothing sent until Apply.

Edits stay pending. Key Mapping and Lighting each have their own Apply and Discard, and every keymap send asks first.

Evidence for every model.

Each listed model shows whether a feature is only in RK's files, checked from source, or verified on hardware with this app.

How it works

  1. 01

    Connect over USB.

    Plug in the keyboard and pick it in the browser dialog. Connecting sends nothing.

  2. 02

    Stage your edits.

    Change keys, chords and lighting. The pending count shows what is waiting.

  3. 03

    Review and Apply.

    Apply sends only that tab's changes. A keymap Apply replaces the whole map (9 reports) after you confirm.

Before you write a keymap

This app talks to the keyboard directly. Four things to know first.

  • No readback.

    The app can't read the keyboard's settings. It starts from what this browser last sent, or from app defaults.

  • Whole map every time.

    Each Key Mapping Apply sends the complete keymap, including keys you didn't touch.

  • Mac mode on the tested RK61.

    On the RK61 0055, any keymap send turned off the keyboard's own Mac mode. What brought it back: hold Fn+Space until the backlight flashes, then Fn+S. Then use Resend lighting to restore your colors.

  • No rollback.

    If a transfer fails part-way the keyboard may be partly updated. Apply again.

Questions

Which browsers work?
Desktop Chrome, Edge or Opera. Firefox, Safari and mobile browsers don't support WebHID.
Does it work on a Mac?
Yes, in one of those browsers. On the tested RK61 a keymap send turns off the keyboard's own Mac mode; see Before you write a keymap.
Will it work with my keyboard?
Only models with a shipped RK configuration that use the classic RK report over USB. Others are refused before anything is sent. Check your model's evidence label.
Can it read my current settings?
No. It shows what this browser last sent, or app defaults.
Where are my settings saved?
In this browser only: one record per keyboard with the last applied keymap, lighting and per-key colors. No accounts, profiles or uploads.
Does Bluetooth or 2.4 GHz work?
No. Use a USB cable.
Can I try it without a keyboard?
Yes. Demo mode opens any listed model. Apply is simulated: nothing is written to hardware or saved.
Is this official RK software?
No. It is unofficial and not affiliated with Royal Kludge. It is a modified version of KludgeKnight by Vince Mi, released under GPL-3.0.

Pick a keyboard to explore

Demo mode lets you explore the interface without a keyboard. You can stage edits and press Apply, but Apply is only simulated: nothing is written to hardware or saved in this browser, and a demo apply is never evidence that a model works.
