Jitsi Meet

Jitsi Meet is the most popular open-source video conferencing solution in the world, with nearly 29,000 GitHub stars. It provides high-quality, encrypted video and audio calls directly in the browser without requiring any downloads or account registration. Users simply visit a URL and start a meeting.

Jitsi Meet supports features such as screen sharing, virtual backgrounds, hand raising, chat, polls, live streaming to YouTube, and integration with calendar apps. It scales to handle large meetings and provides end-to-end encryption for small calls. The platform is built on WebRTC and is deeply integrated with the Matrix and Element ecosystem.

Licensed under Apache-2.0, Jitsi Meet can be self-hosted on any server using Docker, and is also available as a free managed service at meet.jit.si. It is maintained by 8x8 and used by millions of users worldwide, making it the go-to open-source alternative to Google Meet and Zoom.
