WebRTC

WebRTC (Web Real-Time Communication) is the open-source project and API set that enables secure, peer-to-peer (P2P) video, voice, and data exchange directly between browsers and mobile applications.

WebRTC delivers high-performance real-time communication (RTC) capabilities directly to the browser, eliminating the need for plugins or proprietary software. The technology is an open standard, backed by industry leaders like Google, Apple, and Mozilla, and is implemented via three core JavaScript APIs: `MediaStream` (for accessing local camera/mic), `RTCPeerConnection` (for managing peer connections), and `RTCDataChannel` (for generic data transfer). It mandates encryption using DTLS and SRTP and handles complex networking challenges—specifically Network Address Translation (NAT) traversal—by leveraging STUN and TURN servers. This robust framework powers major applications, including Google Meet and Microsoft Teams, ensuring low-latency, secure P2P media streaming.
