We use Mattermost. Its great, but you really get lost in topics quickly and its hard to follow them. Especially with bots that you can't remove from conversation when you need it. We also had to mumbo jumbo LDAP support via GitLab which is suboptimal and there seems to be no way to remove users forever from it, only deactivate them.
The threads here look very nice and entire thing reminds on forum/email conversation. With free LDAP and AIM support I am certainly going to take a deep look.
Zulip makes keeping track of threads a breeze, you can basically create a feed of only the topics you want to see (you mute others) and you zoom in to a single topic to read all of it, or zoom out to see it interleaved in the chronological timeline of all messages in the company. It's fantastic because you can never get lost.
I've used Zulip in the past. Very nice software. At the time (they still may), push notifications were supported for self-hosted servers. It was a joy to use the software.
