LiveKit is an open source project focused on real-time audio and video application development , based on WebRTC technology to build a complete solution . Its core technology architecture contains the following core components:
- SFU Media ServerThe main architecture, written in Go, is based on the Selective Forwarding Unit (SFU) implemented in Pion WebRTC, which is responsible for intelligently routing media streams.
- Multi-platform SDK: Provide JavaScript/TypeScript, iOS, Android and other client development kits
- Two-tier deployment modelSupport for both cloud hosting services (LiveKit Cloud) and private deployments.
The architecture design follows the WebRTC standard protocol and significantly optimizes bandwidth consumption in large-scale scenarios through SFU technology. The server side contains enterprise-level functional modules such as token generation, API calls and webhook reception, while the client side SDK encapsulates complex logic such as device management and codec processing. This architecture is particularly suitable for real-time interaction scenarios that require low latency (typically <500ms).
