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.

The main feature is to be able to see when alt+key or shift+key is pressed, the
keyboard tester was not able to do this.

Here is a video of me using it.

I tend to use keyboard tester a lot as I build a lot of weird keyboards so I
suspect this one to get a lot of use and may grow over time, but for now it
works good enough for me.

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.
