Tincan

Key Features

• Everything runs over one WebRTC connection between the two browsers. A small Go server only does signaling and STUN, with no TURN relay.
• Screen sharing with tab or system audio, and camera quality from 360p to 1080p.
• File transfer with Cauchy Reed-Solomon coding, 16 data and 4 parity shards per block, over unreliable data channels.
• Resumable transfers: blocks are content-addressed with SHA-256 and kept in IndexedDB, so a file continues after a drop, even in another room.
• PIN-protected rooms, a live lobby, and four games: Tic-tac-toe, Three pieces, Connect four and Quoridor.
