   Element has come a long way, and is now a fully-featured group chat application, with spaces (to group several rooms), numerous bridges so people are not locked in one single tool, and great integrations.

   Zulip is a very good free and open source software that helps people to conversation to each other on random and some important topics separately. A usercan see who is online or ofline at the real time that is awesome.

   Positive comment by JonasF · Nov 21, 2025

   Superior to Teams in terms of performance and most importantly because of the Threading model, which allows asynchronous parallel collaboration on multiple issues.

   Slack isn't constantly trying to lock you into its ecosystem. It also lets you set your default browser when opening links to something other than Edge.

   Open source, very powerful. Can be hosted independently on own hardware but also as-a-service. Does the exact same without limiting the user to one service provider or client.
