Side by side
Chat, meetings, calls and file collaboration built on Microsoft 365, with SharePoint behind team files and optional phone system.
A self-hosted peer-to-peer WebRTC meeting app with browser rooms, screen sharing, chat, whiteboard and recording, and no time limits.
The client is heavy and the chat experience is clumsier than Slack; in the EU it is now sold separately from some Microsoft 365 plans.
Peer-to-peer meshes degrade beyond a handful of participants, and it is mainly one developer's project under AGPL.
