Why use LiveKit?

LiveKit differentiates itself through several key advantages: Build faster with high-level abstractions: Use the LiveKit Agents framework to quickly build production-ready AI agents with built-in support for speech processing, turn-taking, multimodal events, and LLM integration. When you need custom behavior, access lower-level WebRTC primitives for complete control. Write once, deploy everywhere: Both human clients and AI agents use the same SDKs and APIs, so you can write agent logic once and deploy it across Web, iOS, Android, Flutter, Unity, and backend environments. Agents and clients interact seamlessly regardless of platform. Focus on building, not infrastructure: LiveKit handles the operational complexity of WebRTC so developers can focus on building agents. Choose between fully managed LiveKit Cloud or self-hosted deployment — both offer identical APIs and core capabilities. Connect to any system: Extend LiveKit with egress, ingress, telephony, and server APIs to build end-to-end workflows that span web, mobile, phone networks, and physical devices.

What is LiveKit?

LiveKit is an open source framework and cloud platform for building voice, video, and physical AI agents. It provides the tools you need to build agents that interact with users in realtime over audio, video, and data streams. Agents run on the LiveKit server, which supplies the low-latency infrastructure (including transport, routing, synchronization, and session management) built on a production-grade WebRTC stack. This architecture enables reliable and performant agent workloads.
