What is Mastty?

Mastty is an open-source, self-hosted team chat and collaboration platform similar to Microsoft Teams or Slack. It allows teams to communicate via messaging, voice/video calls, file sharing, task management, and more - all within a single application.

As Mastty is self-hosted, you get full control and ownership over your data. You can host it on your own servers or cloud infrastructure for maximum privacy and customization. This also eliminates any third-party accessing or mining your team's sensitive information.

Mastty provides persistent chat rooms, 1-on-1 messaging, voice/video conferencing using WebRTC, and built-in VoIP support. It allows seamless sharing of files and images. You also get team calendars, task management, user roles/permissions, and more collaboration capabilities out of the box.

Being open-source software, Mastty is free to use and can be modified or extended as needed. It has mobile apps for Android and iOS for access on the go. Overall, Mastty is a great self-hosted alternative for teams that want control over their communications and collaboration stack.
