About Mattermost Beta

Secure workplace messaging puts team collaboration back in your control. Mattermost Beta is a self-hosted communication platform that lets your organization keep sensitive conversations behind your own firewall—no third-party cloud required.

Stay connected across your team with flexible messaging options. Create private groups for focused discussions, have one-to-one conversations with colleagues, or broadcast messages team-wide. Sharing files is seamless; easily exchange and view images directly in your chat threads.

Integrate your existing tools without leaving the app. Connect in-house systems with webhooks and use Slack-compatible integrations to pull data from your wider tech stack. This means your messaging hub becomes a central hub for all workplace communications.

Mattermost Beta requires Mattermost Server v10.11.0 or newer to function properly. You'll need a valid server URL to get started—your organization can host its own instance to maintain complete data ownership and security. Experience workplace messaging designed for teams that demand privacy and control.
