Who each one suits
Mattermost
- Organizations that must keep chat on their own servers or air-gapped networks
- DevOps and security teams that run incident response from chat
- Small technical teams comfortable hosting their own server
Microsoft Teams

- Companies that want phone calling inside their chat app
- Teams that co-edit Word, Excel and PowerPoint files
Worth knowing
Mattermost
- No prices are published: Professional, Enterprise and Enterprise Advanced are quoted by sales and sold as prepaid annual seat subscriptions.
- Entry shows only the latest 10,000 channel messages and has community support only; the vendor suggests it for teams of fewer than 50 users.
- It is self-hosted by design; the only vendor-hosted option described is single-tenant Mattermost Cloud Enterprise, arranged through sales.
- Team Edition has no single sign-on, and the vendor does not recommend it for government or sensitive commercial workloads.
Microsoft Teams
- The free version is built for one person: group calls stop at 60 minutes and 100 participants, with 5 GB of cloud storage.
- Teams Essentials and the Microsoft 365 Business plans stop at 300 users; larger organizations need Teams Enterprise or Microsoft 365 E3 or E5.
- There is no Linux desktop app: Microsoft points Linux users to a progressive web app and says the Linux client is no longer supported.
- Webinar hosting is left out of Teams Essentials and Business Basic, and phone service, Teams Premium and Copilot are separately priced add-ons.
