What is WebRTC?

WebRTC (Web Real-Time Communication) is an open-source project that enables real-time audio, video, and data communication directly between browsers and devices. It powers modern video calls, file sharing, and interactive applications without plugins or third-party software.

Developed by Google and standardized by the W3C and IETF, WebRTC is now a core technology for peer-to-peer communication on the web. It allows users to connect instantly, securely, and privately, making it the backbone of many innovative web applications.
