## Good for

- 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

## Worth knowing

- 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.
