I’m been trying to stand up a zulip instance. It’s working but I haven’t used it much. I want a feature complete jitsi instance to go with it and that’s only partially implemented right now.
That said, zulip does seem like the best option for me presently.
Haven’t tried revolt.
Mattermost seems to be perpetually entangled but being disentangled from some other suite. Confusing and frustrating.
I haven’t tried rocket chat for 5 years or so. I think last time I read about it people were complaining that the FOSS plan is very limited.
Are there any restrictions on a FOSS instance? Is there a pay wall?
