Mattermost: What It Is and How It Works
Mattermost is a self-hosted, open-core collaboration platform that unifies secure messaging, runbook automation, and project tracking in one place. Deploy on-premises, private cloud, or air-gapped to keep full control over data and compliance.



What Is Mattermost?
Mattermost combines Channels (chat), Playbooks (workflow automation), and Boards (tasks) to accelerate mission-critical work. Admins manage users, devices, and policy centrally while teams collaborate in real time across secure, searchable workspaces.
How Mattermost Works
- Channels: Persistent, searchable conversations with messaging, calls, and screen share for operational teams.
- Playbooks: Repeatable runbooks with checklists, owners, and timeline to drive incident and release workflows.
- Boards: Kanban and task tracking for projects and sprints with status, assignees, and due dates.
- Integrations: Connect GitLab/GitHub/Jira, CI/CD, and 700+ tools via plugins, webhooks, API, and Zapier.
- Security & Admin: SSO via SAML/OIDC/AD-LDAP, data encryption in transit and at rest, retention and compliance export.
