A dice-rolling app I made some pixel art dice for, wrote in React, used ChakraUI, and hosted on Vercel since before that was cool to say. Or maybe it's not anymore.
[Not Supported] A fully customizable Unity UI dev console. This was a fun little project I did several years ago. This may or may not still work, I haven't used Unity in some time due to their runtime fee nonsense. I would like to make a similar project for Godot Engine, so keep an eye out for that.
