Overview:
Mattermost is an open core, self-hosted collaboration platform built with Go and React. It provides chat, workflow automation, voice calling, screen sharing, and AI integration for organizations that want a private alternative to public cloud messaging tools. It runs as a single Linux binary with PostgreSQL and is released monthly under an MIT license. Organizations deploy it on-premises or use a cloud-hosted version for use cases like DevSecOps, incident resolution, and IT service desk operations.

Why It Matters:
Mattermost delivers a core messaging and automation platform that organizations can run entirely on their own infrastructure. Its self-hosted deployment, PostgreSQL backend, and single-binary architecture make it suitable for teams that need full data control. The integration ecosystem—APIs, webhooks, slash commands, Apps, and plugins—allows developers to build custom workflows without relying on third-party servers. Monthly releases and an MIT license support predictable, transparent software maintenance.
