Mattermost is a self-hosted collaboration platform with channels, direct messages, threads, calls and playbooks, built for teams that want to run chat on their own servers. Team Edition is a free, open-source build for small teams, hobbyists and personal use, intended for fewer than 250 users and without SSO. The free Entry mode of the Enterprise Edition includes most paid features but shows only the latest 10,000 channel messages. Paid subscriptions are priced per seat through Mattermost's sales team.
Technical teams that want Slack-style chat on infrastructure they control.
