What is it?

DashBeam is a file transfer app for desktop, Android, a command-line client, and a browser-based receiver. Files move directly between devices over encrypted QUIC connections built on Iroh, so they are not uploaded to a cloud server. Transfers are verified chunk by chunk with BLAKE3 hashing, and interrupted transfers can resume without re-sending data that has already arrived.

Devices can find each other on the same local network through mDNS, or be paired once with a code and later send files without copying a ticket. A single share can be sent to a link, QR code, or ticket string, and the receiver does not need to install anything when using the web app. Connections can switch networks mid-transfer, and relays carry traffic when a direct path cannot be established. Users can also run their own relay server.
