After using ergonomic keyboards for over a decade I designed one that’s close to perfect - not for most, but definitely for me.

Revolt Keyboard
https://ntkstudio.net/
Revolt is the split ergonomic keyboard that puts the user first. It prioritises an abundance of keys over a tiny footprint, a practical layout over trendy looks, and a diy-friendly, modular build over surface-deep minimalism.
It boasts 68 low-profile switches on a tented base, backlit home-row keys to help you find your bearing, and a single microcontroller running the show and providing touchpoint-mouse functionality.
It’s designed to last you for decades with no issues, but if any do come up it’s easy and cheap to fix without complicated disassembly.
