I am working on a Django-based JS-free forum[1] that I can self-host. Still need to work on some essential things, but the basic forum functionality is already there.
JS-ful in some parts - but mostly Rust cloudflare workers WASM. It can self-host as well in a single binary + sqlite. MIT.
Trying to figure out a good defense to the bot-infestation problem next.
