This article covers 5 free open source alternatives to Microsoft Teams. Microsoft Teams is a team communication and collaboration platform where people can interact with their colleagues and teams with team channels, video calls, chats, voice calls, and host team meetings via video conferences. It also supports file sharing and integration with other Microsoft and third-party tools along with no limitation of users.

My goal in this article is to cover similar tools for team communication but open source. There are two types of tools in this article, web-based which you can access anywhere with a web browser and desktop clients which you have to install or setup on your PC. All these tools have almost similar essential features for team communication along with their own set of additional features. With that said, let’s check them out one by one.

5 Free Open Source Alternatives to Microsoft Teams


Open Source Video Conference Tool with Recording, Live Stream

The first tool in this list is Jitsi which is a web-based video conferencing tool. This tool is absolutely free to use with no paid-tier at all. There is no limitation on the number of users, in fact, there is no need for creating an account. You can simply enter a unique link and start the video conferencing.
