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

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.

Tools

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

Install

[!TIP] 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:

MacOS

brew install livekit

Linux

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

Livekit

Install / Use
