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).
