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.

• Scalable, distributed WebRTC SFU (Selective Forwarding Unit)
• Modern, full-featured client SDKs
• Built for production, supports JWT authentication
• Robust networking and connectivity, UDP/TCP/TURN
• Easy to deploy: single binary, Docker or Kubernetes
• Advanced features including:
  • speaker detection
  • simulcast
  • end-to-end optimizations
  • selective subscription
  • moderation APIs
  • end-to-end encryption
  • SVC codecs (VP9, AV1)
  • webhooks
  • distributed and multi-region

• LiveKit Meet (source)
• Spatial Audio (source)
• Livestreaming from OBS Studio (source)
• AI voice assistant using ChatGPT (source)

• 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

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

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.

• CLI - command line interface & load tester
• Docker image
• Helm charts

The following will install LiveKit's media server:

brew install livekit

curl -sSL https://get.livekit.io | bash

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

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:

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

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!

lk room join \
    --url ws://localhost:7880 \
    --api-key devkey --api-secret secret \
    --identity bot-user1 \
    --publish-demo \
    my-first-room

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.
