Overview

utsuru is a WebRTC utility that accepts track packets from a single source and forwards it to multiple mirrors.

Some situations you might want to use utsuru include:

• You want to broadcast to Discord without being limited to screen sharing.
• You want to broadcast a single feed to multiple Discord calls simultaneously.
• You want to use OBS to broadcast to a WebRTC remote peer that does not provide a WHIP endpoint.

Features

• Portable and lightweight:
• The entire application fits in a single binary.
• Minimal CPU and memory footprint.
• Web UI and REST API for managing mirrors.
• Track packets are sent from source to mirrors as is, no transcoding.
• Discord Live is implemented using the WebRTC protocol (same as Discord web client).
