This GitHub repository details "Alfajer," a private 1-to-1 video/audio calling Progressive Web App (PWA) built using WebRTC for media transmission and a custom Bun+ElysiaJS WebSocket signaling server. The architecture emphasizes privacy with no persistent storage, logs, or accounts, and features end-to-end encryption notes via RTCRtpScriptTransform, though it's currently disabled pending a cross-browser capability handshake. Recent commits detail a "5-tier UX overhaul" and automation for TURN secret rotation.
