Mattermost is an open source platform that provides secure collaboration for technical and operational teams that work in environments with complex nation-state level security and trust requirements.
Mattermost is built specifically for technical and operational use cases, including software development and engineering workflows, and integrates deeply with a rich ecosystem of third-party developer tools. Mattermost gives companies full control over their data; with self-hosted and private cloud deployment options and access to the source code, developers can contribute directly to a shared, flexible, and extensible platform built just for them.
