In addition, the Go SDK includes client capabilities, enabling you to build automations that behave like end-users. | Language | Repo | Docs | | :---------------------- | :-------------------------------------------------------------------------------------- | :---------------------------------------------------------- | | Go | [server-sdk-go](https://github.com/livekit/server-sdk-go) | [docs](https://pkg.go.dev/github.com/livekit/server-sdk-go) | | JavaScript (TypeScript) | [server-sdk-js](https://github.com/livekit/server-sdk-js) | [docs](https://docs.livekit.io/server-sdk-js/) | | Ruby | [server-sdk-ruby](https://github.com/livekit/server-sdk-ruby) | | | Java (Kotlin) | [server-sdk-kotlin](https://github.com/livekit/server-sdk-kotlin) | | | Python (community) | [python-sdks](https://github.com/livekit/python-sdks) | | | PHP (community) | [agence104/livekit-server-sdk-php](https://github.com/agence104/livekit-server-sdk-php) | | ### Tools - [CLI](https://github.com/livekit/livekit-cli) - command line interface & load tester - [Docker image](https://hub.docker.com/r/livekit/livekit-server) - [Helm charts](https://github.com/livekit/livekit-helm) ## Install > [!TIP] > 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. The following will install LiveKit's media server: ### 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/home/get-started/authentication/#creating-a-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: ```shell lk token create \ --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 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. ## 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 1.23+ is installed - GOPATH/bin is in your PATH Then run ```shell git clone https://github.com/livekit/livekit cd livekit ./bootstrap.sh mage ``` ## Contributing We welcome your contributions toward improving LiveKit! Please join us [on Slack](http://livekit.io/join-slack) to discuss your ideas and/or PRs. ## License LiveKit server is licensed under Apache License v2.0. <!--BEGIN_REPO_NAV--> <br/><table>
