We (the Recurse Center) have been using Zulip since early 2013, and it is the core of our online community. Zulip is excellent both for small teams (we use it for our team of 7) and big groups - we also run a realm with over 1,000 users posting 10s of thousands of messages monthly. I can't recommend it highly enough.

How do you handle high availability for Zulip? Last I looked that was a problem for it.

  We don't run our own instance; we're hosted by zulipchat.com. Perfect uptime isn't a priority for us, so I don't know what (if any) availability they promise. But we've had almost no downtime over the past five years, and we've certainly had less than the public Slack outages I've seen folks talking about on Twitter :)

  Zulip founder here. It's definitely possible to run a Zulip server with essentially no downtime. E.g. the main zulipchat.com service has had approximately 10 user-facing outages with a median duration of 5-10 minutes over the last 5 years (there was one while we still only had a few hundred users that lasted overnight), most of them in the middle of the night. Happy to talk more about this for anyone curious; there are some fun stories (like migrating from MySQL to Postgres as our primary database technology with <30 minutes of downtime early in its development). We don't have a public uptime SLA for zulipchat.com uptime yet, but we're happy to make them for individual customers (and I suppose we should add one). If you're self-hosting, our commercial support offerings will help you setup your servers in a way that achieves your uptime goals; because Zulip is so stable, usually folks just go with a hot spare (our enterprise customers generally only report downtime related to server upgrades, which is usually avoidable).
