Just recently I looked at hosting an old school forum. I don't want to load all the PHP and MySQL baggage on my server or even run it in docker, so I looked for Python solutions. Found PunkwebBB. Was happy for a short time with it, until I tested it more in depth with no scripts. Unfortunately, while it has some good fallbacks in some places, it doesn't have them everywhere and some buttons just don't do anything without JS. It also uses Htmx. Completely unnecessary JS, considering the function of the buttons.
I considered forking it. But the amount of work to remove the needless JS, and repair it ...
So now I am building my own forum completely without JS, and with Python Django doing a lot of heavy lifting.
