FileBeam
Transfer files between devices.
FileBeam transfers files directly between any two devices — peer-to-peer via WebRTC. No cloud, no uploads, no size limits, no sign-up. Files go directly device-to-device, end-to-end encrypted. Works cross-platform: iPhone ↔ Android ↔ Windows ↔ Mac ↔ Linux. Just drop files, get a 6-digit code, enter it on the other device. Files beam directly via WebRTC. Built with Next.js, WebRTC, and a tiny socket.io signaling relay. Open source.
Hey Product Hunt!
I built FileBeam because every file transfer tool either uploads your files to a server (WeTransfer, Google Drive) or only works on one platform (AirDrop).
FileBeam uses WebRTC to beam files directly from device A to device B. The files themselves — the actual bytes, names, and sizes — never touch any server. They travel only over an encrypted peer-to-peer data channel.
To be fully transparent: a tiny signaling relay (a ~130-line socket.io server) does pass the 6-digit code and connection handshake so the two devices can find each other. That's inherent to how WebRTC works — two devices need to exchange connection info before they can connect directly. But that relay never sees file data, names, or sizes, and rooms are destroyed when the transfer ends.
No size limits, no sign-up, no tracking. Works on any device with a browser.
Would love your feedback! Happy to answer questions about the WebRTC setup or the architecture.
Also check out ShrinkRay, ConvertIt, Cutout, DevToys, ExifErase, and LinkClean — same privacy-first model!
