Broadcast Box – sub-second WebRTC broadcasting

Broadcast Box is a self-hosted WebRTC broadcasting platform focused on very low-latency one-to-many streaming.

It is designed for users who want to broadcast a screen, webcam or encoded video feed to other people without assembling a conventional streaming stack. Publishers can use a browser, OBS Studio, FFmpeg or GStreamer, while viewers receive the stream through a browser-based interface. A Go backend handles WebRTC sessions, with a React and TypeScript frontend providing publishing, playback and administration facilities.

This is free and open source software.
