Date: June 20, 2026 Today I got sick of my go to online keyboard tester <https://www.keyboardtester.com/> not supporting holds and fighting an issue with holds on one of my boards, I vibed out a replacement. I did a bit of work with it to get it how I wanted. gpt5.4 still likes to make lots of cards and build readable sites with a reasonable width for reading, not full page apps.

I can already think of a whole list of features like supporting keycodes for js, pygame, zmk, qmk. But for now I’m just building what I need and not overcomplicating it.
