DashBeam is an open-source peer-to-peer file transfer app for desktop, Android, web, and CLI. It lets you send files and folders anywhere in the world with no accounts and no cloud storage. It is built on the Iroh networking stack and uses ticket-based sharing with NAT hole punching and encrypted relay fallback.
Yes. DashBeam is free and open source (AGPL-3.0) with no file size limits, no upload quotas, and no accounts. If you benefit from this work, consider supporting development through Buy Me a Coffee or GitHub Sponsors.
You can transfer anything: images, videos, documents, folders, and more. Integrity checks use BLAKE3 on both ends, so files are verified during send and receive. Transfers are resumable if interrupted.
DashBeam uses end-to-end encryption with QUIC + TLS 1.3. Files go directly between devices and are not stored on a cloud server. Relays only see encrypted traffic. Tickets authenticate the intended sender before a transfer starts.
Unlike browser-only WebRTC tools, DashBeam is a native app (plus Android, web, and CLI) built on Iroh/QUIC. You can send large files and full folders with pause/resume, fewer browser limits, and BLAKE3-verified streaming. See our full comparison for details.
