LiveKit

LiveKit: The open-source WebRTC and cloud platform for building high-scale, real-time voice, video, and multimodal AI agents.

LiveKit provides the complete, end-to-end stack for real-time communication (RTC). We offer a globally distributed cloud platform and a powerful open-source WebRTC media server (written in Go) for self-hosting: you choose the deployment. Our extensive SDKs (JS, Python, Go, etc.) abstract away WebRTC complexity, letting over 20,000 developers rapidly build applications like video conferencing, livestreaming, and interactive AI agents. Key features include scalable SFU architecture, Egress (recording/multistreaming), and a dedicated framework for multimodal AI agent development.
