Everything about it is open source, the only limitation is microcontrollers that support circuitpython. Most of the controllers that work with QMK also work with KMK. The pi pico for example that's used is much cheaper than the typical arduino pro mini, and comes with more storage and i/o pins.
Oh that's pretty nifty. I assume it's not used as much because it's more expensive to implement?

I see. I guess it's a mindshare thing then, I myself only heard of KMK from your project!
