Element Call vs BigBlueButton
Both are free/open-source alternatives to Zoom. Here's how they stack up — verified facts, no spin.
Element Call
Decentralized, end-to-end encrypted calls on the Matrix network.
Element Call is a native Matrix video-conferencing app: end-to-end encrypted by default, federated across Matrix homeservers, and free to use or self-host. It is the best fit for teams that want secure, decentralized calls with no single company controlling the infrastructure — calls can even happen between users on different homeservers.
BigBlueButton
Open-source virtual classroom and web conferencing.
BigBlueButton is an open-source web-conferencing system built for online teaching, with slides, whiteboard, breakout rooms, and polls. It is the strongest fit when the priority is education and interactive sessions rather than casual calls.
