What you give up vs Microsoft Teams
- Many advanced features (LDAP/AD, SAML/SSO, compliance exports, high availability) are gated behind paid Enterprise tiers
- Search and message UX feel less polished than Slack
- Voice/video calling is more limited than Teams' full meetings stack
- Smaller third-party app/integration marketplace than Slack
What you gain
- • Full data ownership — self-host Mattermost on your own infrastructure.
- • No per-seat SaaS bill (Microsoft Teams: Microsoft 365 lock-in).
- • Open-source code you can audit and extend (MIT).
