FluxBB VS Discourse

FluxBB [1], the PHP based forum that powers the Archlinux wiki works fine without JS, and IMHO looks fine too.

If you are looking for something minimal with threading support, fossil scm [2] includes a forum. You can checkout the forum for fossil itself which is powered by fossil.

> Tell me another platform that is free, has realtime chat, voice and video, has stable service, allows sharing images and other media, with good ownership management... and is open source.

Nextcloud Talk: https://nextcloud.com/talk/

Self hosting and some assembly required. I've run all of them on cheap VPSes to explore a Slack/Discord replacement, neither was mindblowing but all of them seemed okay (Nextcloud's offering was rather barebones, though).

Audio and video support varies because getting those right is challenging, at best you'd just integrate with something like Jitsi, that one's actually pretty good for meetings and such: https://jitsi.org/ and has a cloud version too: https://meet.jit.si/ (yet people still go for Zoom and it's odd UI/UX choices)

I actually rather liked forums back in the day, but I guess nobody will be setting up that many phpBB instances in the current year, though projects like Discourse also seem promising: https://www.discourse.org/

I don't think many people at all will be leaving Discord, due to how entrenched the platform is (network effect): if you want people to help you with what you're working on, you go where they are, not vice versa.

Discourse is also open source https://github.com/discourse/discourse

I disagree. Lots of communities, e.g. Julia or Stan, use https://www.discourse.org. Discourse is GPL2 and emulates old Internet forums.

Discourse is open source: https://github.com/discourse/discourse

You could hook it up to a mail provider and can host it yourself for less if you wanted.

Discourse is OSS (GPL v2): https://github.com/discourse/discourse/blob/main/LICENSE.txt. So if someone can figure out a way to get it to work on older browsers, that would definitely be of interest. I'm not sure how trivial this is though (e.g. from looking around there are features it uses like the chaining operator).

The software is discourse, so it may feel a bit different than the old forum (and reddit for that matter), but I've imported much of the original tavern structure and rules.

What about Lemmy? BeeHaw? Discourse?

would discourse work for this at all? https://www.discourse.org/
