What is Mattermost?
Open source team collaboration platform for secure messaging, channels, playbooks, and workflow coordination. Mattermost is often evaluated by teams that want a Slack-style experience with self-hosting, compliance controls, and deeper ownership of communication data.
Mattermost is worth evaluating if you need an open source option for communication teams. The most important questions are whether it matches your workflow, whether the license fits your use case, and whether your team wants a hosted product, a self-hosted deployment, or both.
