WebRTC
A browser technology enabling real-time audio, video, and data communication directly between users without plugins.
Definition
WebRTC (Web Real-Time Communication) is an open-source technology built into modern browsers that enables peer-to-peer audio, video, and data transfer without requiring plugins, downloads, or intermediary servers for the media stream itself. It handles the complex networking challenges of real-time communication including NAT traversal, codec negotiation, and adaptive bitrate streaming.
WebRTC powers video calls, screen sharing, file transfer, and real-time collaboration features directly in the browser, making it the foundation for tools like Google Meet, Discord, and many telehealth platforms.
Why It Matters
WebRTC eliminates the friction of installing software for real-time communication. Users simply click a link and connect. This dramatically reduces drop-off for video consultations, live support, virtual events, and collaborative tools.
For businesses, WebRTC enables embedded video and voice features directly in web applications without third-party dependencies, creating seamless experiences for client calls, team collaboration, and live customer support.
Examples in Practice
A consulting firm embeds WebRTC-powered video calls directly into their client portal, allowing clients to start strategy sessions with one click rather than downloading Zoom or Teams.
An event platform uses WebRTC for virtual networking rooms where attendees can video chat in small groups, with the browser handling all audio/video without any software installation.
