Zero-backend WebRTC video chat implementation with high technical depth and immediate actionability.
Summary
A developer built a browser-to-browser video chat in ~250 lines using WebRTC's three core APIs (getUserMedia, RTCPeerConnection, and manual SDP/ICE signaling) with zero backend, SDKs, or cost. The signaling handshake is reduced to three messages—offer, answer, and confirmation—where users copy-paste JSON blobs between tabs instead of relying on WebSocket or Firebase. The 8-commit Next.js repo demonstrates each step from local webcam preview to full peer-to-peer video, using Google's STUN server for NAT traversal.
