PlugNMeet

PlugNMeet comes from Spain. Its code is public, it builds on WebRTC and it can be hosted on your own server. Typical uses are video meetings, webinars, online lessons and collaboration embedded in other sites. In the browser, participants get HD audio and video, screen sharing, open and private chat, recording, RTMP broadcasting, breakout rooms, polls, a joint whiteboard and notepad, E2EE, captions and translation. For developers there are APIs, SDKs and connections to CMS and learning platforms. A free entry tier exists; Google Meet counts as an alternative.
