# PeerJS: Simple peer-to-peer with WebRTC [![Backers on Open Collective](https://opencollective.com/peer/backers/badge.svg)](#backers) [![Sponsors on Open Collective](https://opencollective.com/peer/sponsors/badge.svg)](#sponsors) [![Discord](https://img.shields.io/discord/1016419835455996076?color=5865F2&label=Discord&logo=discord&logoColor=white)](https://discord.gg/Ud2PvAtK37) PeerJS provides a complete, configurable, and easy-to-use peer-to-peer API built on top of WebRTC, supporting both data channels and media streams. ## Live Example Here's an example application that uses both media and data connections: https://glitch.com/~peerjs-video. The example also uses its own [PeerServer](https://github.com/peers/peerjs-server). ---
