AirDrop for any device. No Limits. 100% Private.
Send 10GB, 50GB, or 100GB+ files straight from your device to theirs. No 2GB caps like WeTransfer. Zero cloud storage, 100% private end-to-end encryption.
Sending takes seconds, not sign-ups
No cloud storage, no waiting for upload queues, no accounts. Three simple steps and your files beam directly device to device.
Select your files or folders
Drag and drop any files or entire folders. No size limits, no compression required. Folders are packaged cleanly right in your browser.
Share your 6-character code
Get an instant 6-character room code, link, or QR code. Send it to your friend, coworker, or your own second device. No sign-up needed.
Stream direct device to device
As soon as they connect, files stream directly between devices with end-to-end encryption. Nothing is ever saved or stored on any server.
Why direct streaming is fundamentally better
Eliminate cloud queues, storage quotas, and third-party servers. Experience pure WebRTC throughput connecting two machines directly with zero compromises.
Direct device to device
Files beam straight between browsers — zero bytes uploaded, stored, or cached on a server.
End-to-end encrypted
Every 64KB chunk is sealed with cryptographic keys held only by the two connected devices.
No file size limits
Send gigabytes or terabytes without compression, subscription paywalls, or memory bottlenecks.
