About

File Tunnel is a tunneling-based real-time file transfer system that relays files without server storage. One sender can simultaneously transmit files to multiple receivers, all of whom must approve before transfer begins. Files are divided into optimized chunks for efficient streaming, and transfers can resume from the last successful point if interrupted. Built with Rust and Next.js, it provides high-performance, secure file transfer through WebSocket communication while maintaining session state with PostgreSQL and verifying file integrity with Blake3 hashing.
