Use Zulip.

The migration out of Slack is actually quite easy and preserves all messages, files, etc. Even the user migration is straightforward, keeping Google or whoever as the identity provider if you prefer.

Zulip is not even close to Slack. It keeps crashing.

I lead the Zulip project and I'm not aware of any common crash issues with either our server or any of our apps.

Thanks for your work on Zulip!

I have some feedback that's annoyingly non-specific.

I used Zulip a few years ago as a contractor. It seemed _fine_, but I didn't love it. Specifically, the UI felt sluggish and generally the experience was somewhat unpolished. Maybe things have changed, a lot happens in a couple years, but there you go

		Just about every UI component has been redesigned over the last two years. So your experience may be different these days :).

I've been using a couple of different Zulip servers for professional communication for several years and haven't had any issues.
