Pairlane – Peer-to-peer file transfer without accounts or uploads

Summary: Pairlane enables direct peer-to-peer file transfers via WebRTC without server-side storage or accounts. Files are end-to-end encrypted by default and transferred through browser or CLI interfaces, with signaling handled by Cloudflare Workers.

What it does

Pairlane transfers files directly between devices using WebRTC DataChannel, with the server only managing signaling. AES-GCM encryption keys are stored in the URL fragment, ensuring no file data passes through the server.

Who it's for

Users needing private, account-free file sharing across browsers and command-line interfaces in typical home or office networks.

Why it matters

It eliminates the need for uploads or server storage, enhancing privacy and simplifying file sharing.
