Side by side

What it does

A virtual classroom server with audio, video, slides with whiteboard annotation, polls, shared notes, breakout rooms, recordings and learning analytics.

Chat, meetings, calls and file collaboration built on Microsoft 365, with SharePoint behind team files and optional phone system.

Watch out

Installation expects a dedicated Ubuntu server with specific versions and plenty of CPU and bandwidth; upgrades between major versions are significant work.

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.
