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

[LiveKit](https://livekit.io) 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](https://github.com/pion/webrtc) implementation.

### Server SDKs

Server SDKs enable your backend to generate [access tokens](https://docs.livekit.io/guides/access-tokens/),
call [server APIs](https://docs.livekit.io/guides/server-api/), and
receive [webhooks](https://docs.livekit.io/guides/webhooks/). In addition, the Go SDK includes client capabilities,
enabling you to build automations that behave like end-users.

### Ecosystem & Tools

- [CLI](https://github.com/livekit/livekit-cli) - command line interface & load tester
- [Egress](https://github.com/livekit/egress) - export and record your rooms
- [Ingress](https://github.com/livekit/ingress) - ingest streams from RTMP / OBS Studio
- [Docker image](https://hub.docker.com/r/livekit/livekit-server)
- [Helm charts](https://github.com/livekit/livekit-helm)

## Install

We recommend installing [livekit-cli](https://github.com/livekit/livekit-cli) along with the server. It lets you access
server APIs, create tokens, and generate test traffic.

### MacOS

```shell
brew install livekit
```

### Linux

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

### Windows

Download the [latest release here](https://github.com/livekit/livekit/releases/latest)

## 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](https://docs.livekit.io/deploy/)

### Creating access token

A user connecting to a LiveKit room requires an [access token](https://docs.livekit.io/guides/access-tokens/). Access
tokens (JWT) encode the user's identity and the room permissions they've been granted. You can generate a token with our
CLI:

```shell
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](https://example.livekit.io) and enter a generated token to connect to your LiveKit
server. This app is built with our [React SDK](https://github.com/livekit/livekit-react).

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

### Simulating a test publisher

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

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.

## Deployment

### Use LiveKit Cloud

LiveKit Cloud is the fastest and most reliable way to run LiveKit. Every project gets free monthly bandwidth and
transcoding credits.

Sign up for [LiveKit Cloud](https://cloud.livekit.io/).

### Self-host

Read our [deployment docs](https://docs.livekit.io/deploy/) for more information.

## Building from source

Pre-requisites:

- Go 1.20+ is installed
- GOPATH/bin is in your PATH

Then run

```shell
git clone https://github.com/livekit/livekit
cd livekit
./bootstrap.sh
mage
```
