dashbeam

DashBeam is a free and open-source file transfer tool that enables direct, peer-to-peer file transfers between devices without relying on cloud servers. It leverages the Iroh networking stack to establish encrypted, end-to-end connections using QUIC and TLS 1.3, ensuring privacy and security. Users can transfer files of any size across desktop (Windows, macOS, Linux), Android, CLI, and web platforms. The tool supports multiple transfer methods: sending via QR code, link, or ticket; pairing devices for recurring transfers; and discovering nearby devices on the same network using mDNS. Key features include resumable transfers, multi-peer broadcasting, roaming across networks mid-transfer, and self-hosted relay support for unthrottled remote transfers. Files are verified using BLAKE3 hashes, and transfers are content-addressed via blobs. DashBeam emphasizes privacy with no accounts, tracking, or ads. It also offers a comparison with similar tools like LocalSend, Magic Wormhole, and PairDrop, highlighting its advantages in speed, cross-network functionality, and resume capabilities. The project is licensed under AGPL-3.0 and has a strong focus on community contribution through Discord and GitHub.
