Ion SFU is a pure Go implementation of a WebRTC Selective Forwarding Unit (SFU) that routes audio, video, and datachannel streams to scale WebRTC sessions efficiently. It can be embedded directly as a Go library or accessed via gRPC or JSON-RPC signaling interfaces, and serves as the engine behind projects like LiveKit and Ion.

Use cases

• build a scalable video conferencing server in go
• forward webrtc audio and video streams to many participants
• self-host a webrtc media server
• implement live streaming with selective forwarding
• detect who is speaking in a group call
• embed an sfu into an existing backend service via grpc
• run a webrtc echo test for testing connectivity

When to choose

• you need a minimal, flexible WebRTC SFU with few external dependencies
• you want to embed SFU functionality directly in a Go service
• you need audio/video/datachannel forwarding with congestion control
• you prefer building your own signaling layer over a batteries-included platform

When to avoid

• you want a complete, batteries-included real-time platform with SDKs - use LiveKit instead
• you need a maintained project with active development - the latest release is from 2023
• you need built-in signaling, recording, or TURN infrastructure out of the box
• your stack is not Go and you cannot run a separate media service
