What you give up vs Microsoft Teams
- Native voice/video calling is limited and usually relies on third-party integrations (Jitsi, Zoom)
- The topic-threading model has a learning curve and can feel unfamiliar to Slack users
- Production installs effectively want a dedicated server; multi-host scaling is involved
- Smaller app/integration ecosystem than Slack
What you gain
- • Full data ownership — self-host Zulip on your own infrastructure.
- • No per-seat SaaS bill (Microsoft Teams: Microsoft 365 lock-in).
- • Open-source code you can audit and extend (Apache-2.0).
