Mattermost is an open source Slack-alternative used by thousands of companies around the world in 14 languages.
You can download our apps from the App Store or Google Play Store, or build them yourself.
We plan on releasing monthly updates with new features - check the changelog for what features are currently supported!
Important: If you self-compile the Mattermost Mobile apps you also need to self-compile and deploy your own Mattermost Push Notification Service.
