SwiftSync is a blazing-fast local file transfer engine. Send 1GB files across your network in seconds, encrypted end-to-end. Built with Rust. Made for you.
Stop relying on cloud storage for simple file transfers.
Direct peer-to-peer connections mean files move at local network speeds—often 10x faster than cloud alternatives.
End-to-end encrypted. Files never touch a server. Only you and your devices can decrypt what's being sent.
Send 1GB, 10GB, or massive files without hitting upload caps or subscription tiers. Your network is the limit.
Local network means internet is optional. Queue transfers when offline, they sync automatically when you reconnect.
Dead simple. Works everywhere.
Built with Rust, Tauri, and Jetpack Compose for maximum performance.
64KB binary chunks with active backpressure management. Send 1GB+ files without maxing out your phone's memory.
Rust daemon monitors your desktop. Drag a file in, it streams to your phone automatically with system notifications.
Send from Gallery, Files, or any app. SwiftSync appears in your Android share menu—zero friction workflow.
Whitelist specific folders on PC. Mobile UI shows a grid to pick exactly where files land—fine-grained control.
NaCl box_seal on every transfer. Server never sees plaintext. Keys live only on your devices.
Queue transfers when offline. When you reconnect, they sync automatically. Perfect for spotty connections.
Zero-knowledge architecture. Your data stays yours.
Files stream directly between devices over WebRTC. No central server relay.
X25519 + XSalsa20-Poly1305. Field-tested, audited, impossible to crack.
No passwords. Devices establish trust instantly via a secure 6-digit PIN handshake.
Open-source. We don't track you, your files, or your devices. Full local control.
