WebRTC (Web Real-Time Communication) is an open-source project that provides web browsers and mobile applications with real-time communication via simple application programming interfaces (APIs). It supports video, voice, and generic data to be sent between peers, allowing developers to build powerful voice- and video-communication solutions. The technology is available as a free download from its website at [https://webrtc.org](https://webrtc.org), where developers can also find documentation, sample code, and other resources to help them implement the technology efficiently. WebRTC is designed to work through NATs and firewalls and is widely integrated into modern web browsers, making it an essential tool for modern web applications needing real-time communication capabilities.
