So I built ledit over the last few nights. Here's a very amateurish promo video.
ledit is open-source and can also easily be self-hosted if you so wish.

My background is in gaming tech and compilers, so I'm not exactly sure what I'm doing. I've used lit + tailwind for the frontend and Node/Express/Postgres as the backend stack. YMMV
Happy to get suggestions for improvements!
