Original: ZeroRelay: Direct Browser-to-Browser Sharing - No Server Ever Sees Your Data
Short summary
ZeroRelay is an open-source P2P mesh app that lets browsers share text, code, and files directly over WebRTC with no central server storage. A Cloudflare Durable Object handles signaling only, while each peer persists data locally in IndexedDB via Dexie. The MIT-licensed project is self-hostable and currently supports same-LAN transfers with STUN-only NAT traversal, with TURN support still pending.
