Jitsi

Jitsi is a set of open-source projects that allows you to easily build and deploy secure video conferencing solutions. At the heart of Jitsi are Jitsi Videobridge and Jitsi Meet, which let you have conferences on the internet, while other projects in the community enable other features such as audio, dial-in, recording, and simulcasting. A vibrant developer community is pushing the envelope of video conferencing quality on the web. Completely free video conferencing, Jitsi is the best, most secure video conferencing solution available for free to anyone. Jitsi Videobridge passes everyone’s video and audio to all participants, rather than mixing them first, resulting in better quality and lower latency. Jitsi is compatible with WebRTC, the open standard for Web communication, and offers advanced video routing support for simulcast, bandwidth estimations, and scalable video coding.
