What works the same as Microsoft Teams

  • Chats and channels as in Teams: pinned chats, chat folders and hidden teams.
  • Send, edit, delete, react, quote-reply and @mention in messages.
  • Channel posts as cards, with the last replies and a full conversation view.
  • Audio and video calls, and screen sharing.
  • The same keyboard shortcuts as Teams.

What is missing

  • It is unofficial and uses the same web APIs as the Teams web app, which can change at any time.
  • You need a Microsoft Teams account to use it.
  • On Linux, it only connects to a Chrome you start yourself with a debug port; built-in login is planned.

How to get started

  1. The project has no ready-made download yet, so you build it yourself with Rust.
  2. To look around first, run it with demo data; no account needed.
  3. To get a Windows exe, run the project build script.
