LiveKit: Real-time video, audio and data for developers

LiveKit is an open source project that provides scalable, multi-user conferencing based on WebRTC. It's designed to provide everything you need to build real-time video audio data capabilities in your applications.

LiveKit's server is written in Go, using the awesome Pion WebRTC implementation.

Documentation & Guides

Live Demos


  • Agents: build real-time multimodal AI applications with programmable backend participants
  • Egress: record or multi-stream rooms and export individual tracks
  • Ingress: ingest streams from external sources like RTMP, WHIP, HLS, or OBS Studio

SDKs & Tools

Client SDKs

Client SDKs enable your frontend to include interactive, multi-user experiences.

Language Repo Declarative UI Links
JavaScript (TypeScript) client-sdk-js React docs | JS example | React example
Swift (iOS / MacOS) client-sdk-swift Swift UI docs | example
Kotlin (Android) client-sdk-android Compose docs | example | Compose example
Flutter (all platforms) client-sdk-flutter native docs | example
Unity WebGL client-sdk-unity-web docs
React Native (beta) client-sdk-react-native native
Rust client-sdk-rust

Server SDKs

Server SDKs enable your backend to generate access tokens, call server APIs, and receive webhooks. In addition, the Go SDK includes client capabilities, enabling you to build automations that behave like end-users.

We recommend installing LiveKit CLI along with the server. It lets you access server APIs, create tokens, and generate test traffic.

The following will install LiveKit's media server:


brew install livekit


curl -sSL | bash

Getting Started

Starting LiveKit

Start LiveKit in development mode by running livekit-server --dev. It'll use a placeholder API key/secret pair.

API Key: devkey
API Secret: secret

To customize your setup for production, refer to our deployment docs

Creating access token

A user connecting to a LiveKit room requires an access token. Access tokens (JWT) encode the user's identity and the room permissions they've been granted. You can generate a token with our CLI:

livekit-cli create-token \
    --api-key devkey --api-secret secret \
    --join --room my-first-room --identity user1 \
    --valid-for 24h

Test with example app

Head over to our example app and enter a generated token to connect to your LiveKit server. This app is built with our React SDK.

Once connected, your video and audio are now being published to your new LiveKit instance!

Simulating a test publisher

livekit-cli join-room \
    --url ws://localhost:7880 \
    --api-key devkey --api-secret secret \
    --room my-first-room --identity bot-user1 \

This command publishes a looped demo video to a room. Due to how the video clip was encoded (keyframes every 3s), there's a slight delay before the browser has sufficient data to begin rendering frames. This is an artifact of the simulation.
