WebRTC Made Easy: Create-Deploy-Evaluate Video Conference

WebRTC enables real-time, peer-to-peer video, audio, and data transmission across browsers using JavaScript. Build private video conference apps by leveraging media capture, encoding, transport, and session management.

WebRTC enables peer-to-peer real-time data transfer over the internet and delivers higher performance than client-server models. It initiates connections via signaling, selects the best route, and lets peers communicate directly.
