Slack alternatives?
(lemmy.ml)
Element/Matrix is pretty much what you're looking for if you need self hosted. Could also look into Jabber/XMPP or IRC but Matrix is going to be way more modern and useable.
Zulip
I found Zulip to be much more intuitive than Slack.
Mattermost
I think Rocketchat is what you're looking for.
I'm forced to use slack for work and I fuckin hate it
Could be worse, you could be forced to use teams!
