I have a ch57x based keyboard/macropad, and hate (unsurprisingly) the (windows only) programming tool that it comes with.

Given that I can use a web based tool for my wooting keyboard, I figured the same must be true for the ch57x, I couldn't find one, so I wrote one.

Capabilities:

  Reading and writing configurations to a ch57x keyboard
  Storing multiple profiles for switching layouts
  Key sequences, media keys, and mouse events

Current limitations:

  Chrome/Chromium, Edge, and Opera only.
    I haven't tested Chromium or Opera so ymmv
    No mobile browser that I'm aware of supports WebHID
  Firefox and Safari will likely never support programming HID devices
