Private device-to-device file sharing fast, simple, secure.
Send files directly between smart phones. When networks block P2P, SendTunnel opens a secure, encrypted tunnel so your transfer still succeeds.
Direct P2P first
Peers connect with QUIC for low-latency, high-throughput transfers. No middlemen in the happy path.
Secure tunnel fallback
If NATs or firewalls get in the way, traffic flows through an encrypted tunnel. Content never stored.
Resumable & reliable
Chunked, verified streaming lets you pause/resume and survive flaky networks without re-sending.
iOS and Android
Same snappy UI for both platforms.
Privacy by design
No cloud storage. No analytics by default. Local keys only. Transparent path indicator (Direct/Relay).
Shared core
Shared Rust core with clean APIs, packaged inside a Capacitor plugin.
Early access coming soon
We'll open the beta very soon, so you can help shape SendTunnel.
