About

Zulip is team chat (like Slack or Discord for work) built around topics, so conversations stay organized instead of scrolling away. Their hosted Cloud plan is free with 10,000 searchable messages and 5 GB of storage. Genuinely usable for small teams. And the whole thing is open source, so you can self-host it for free with no limits.
