Of all the discord clones, this one does look promising I must admit, especially since the dev has mentioned they’d be open to incorporating federation and some encryption abilities down the road. The GPL license is a good mark, and the dev seems pretty chill. Downside is that’s it’s still very rough and in more of a visually polished alpha state. The dev mentioned they’re about to release a major refactor of the codebase, which they hope will fix the sluggishness the server is experiencing after an influx of new users from the Discord dumpster fire.

Personally, I’d still suggest Movim over Fluxer at the moment.

Movim already has a proven scalable back-end, it’s already federated, already provides good encryption, has 90% feature parity with Discord such as Chats, group video calls, screen-sharing with audio (requires chromium browser to share audio for now), its made in the EU, and it’s ready right now, not some time in the future (if Discord users fleeing discord try Fluxer, they’d be likely to bail on it due to the current bugs and just go back to discord). The Movim developer is also currently working on adding in discord-like channels and rooms.

(Movim also doesn’t require an email to create an account, and runs right in your browser, so I’d highly recommend quickly giving it a shot with a friend to see if it can meet your needs! :D)

But that’s just my 2 cents. Fluxer is one to keep an eye on for the future, though.
