The verdict on Zulip
Zulip's distinguishing feature is its threading model: every message belongs to a topic within a channel, which keeps busy, high-volume discussions far more organized than Slack's flat channels — a genuine win for async and distributed teams. It's open source and self-hostable, so you can own your data and escape per-seat cloud costs, and its cloud pricing ($6.67–$10/user) undercuts Slack. The topic model takes some adjustment, the ecosystem is smaller, and self-hosting is technical. But for an async-first, open-source-minded, or distributed team that finds Slack chaotic and expensive, Zulip is a thoughtful, ownable alternative, with a Slack importer built in.
