What is Mattermost?
Mattermost is an open-source, self-hostable team messaging and collaboration platform built for organizations that need control, security and customization that typical cloud chat tools can't offer. Frequently described as a self-hosted alternative to Slack, Mattermost gives teams a familiar channel-based messaging experience while keeping all data on infrastructure they own — a crucial requirement for government agencies, defense, financial services, and any organization with strict security, privacy or compliance needs.
Functionally, Mattermost provides what teams expect from modern chat: organized channels, direct messages, threaded conversations, file sharing, search and integrations, plus voice and screen sharing. But its differentiators are control and extensibility. Because it's open source and self-hosted, organizations can deploy it on-premises or in their own cloud, customize and extend it deeply, integrate it tightly with internal systems, and meet rigorous security and data-residency requirements without depending on a third-party vendor's policies.
Mattermost has increasingly focused on technical and operational teams, offering capabilities tailored to developers and DevOps — tight integration with tools like GitLab, support for incident collaboration and "ChatOps" workflows, playbooks for coordinating operational processes, and a platform that fits naturally into engineering environments. This makes it especially popular where chat isn't just for casual conversation but a core part of how technical work and incident response get done. For security-conscious enterprises, regulated industries, and technical teams that value open source and full control over their communication infrastructure, Mattermost offers a powerful, flexible and trustworthy alternative to closed SaaS chat tools — combining the collaboration features teams need with the ownership, customizability and security that demanding organizations require.
