Overview

Overview

Mattermost is a self‑hosted collaboration hub designed for software development teams, IT operations, and security groups that require full control over their data. It combines persistent chat, voice calls, screen sharing, and AI‑enhanced automation to streamline communication across the entire development lifecycle.

Capabilities & Extensibility

Beyond core messaging, Mattermost offers workflow automation through slash commands, webhooks, and a marketplace of over 700 integrations. Developers can extend the platform with custom plugins, APIs, and drivers, while native mobile and desktop clients keep teams connected on any device.

Deployment Options

The platform runs as a single Linux binary backed by PostgreSQL and can be deployed via Docker, Kubernetes, Helm, or traditional package installs on Ubuntu, Debian, and RHEL. Monthly releases under an MIT license provide regular updates, and a free cloud trial is available for quick evaluation.
