my team tried it for a couple weeks. couldn't stand the threaded "only see what's important" style of chat. it's undoubtedly our least fav part of microsoft teams---the channels and the threads, we all operate in the chat tab and the channels tab has been relegated to announcement posts no one reads. huge shame zulip can't just like... have a toggle for normal chat chronology/presentation. some people have gone way too for trying to efficiency max or "cut out the noise" but chronological chat and a competent search feature will always be the goat.

We've been using it successfully for a long time too. Real nice bunch of fellas. They did remove mobile notifications without a subscription recently and the price is quite high ONLY for notifications. I do not fault them for doing it but it made recommending them a tiny bit more difficult. The other major issues IMO are the super basic mobile client and lack of any kind of native voice/video chat. You get a button that provides a link to a chat service of your choice. For example you pick a Jitsi Meet instance and Zulip gives you button to create and share the url easily. That's it. I wish there were something a little better integrated.

I opened issues which were technically not feasile, it turns out. The server seems to do way too much logic to make this a better app, with offline first or even just "having a search that works" clients.

Sounds like it doesn't look good, then?
