Hi HN,

I built AirDows, a browser-based tool for transferring files between devices using WebRTC.

The idea is simple: open AirDows on two devices, connect them using a QR code or temporary PIN, and send files without creating an account or uploading them for later download.

AirDows attempts a direct peer-to-peer connection first. If the networks cannot establish a direct route, it uses an encrypted TURN relay. The files are not stored by AirDows.

It currently supports:

- Transfers across different networks - QR code and temporary PIN pairing - Direct-to-disk writing in supported browsers - Compatibility mode for other browsers - Large-file transfers - Transfer queues, cancellation, and resume support - PWA installation

It is an early free beta, so both devices need to remain active and performance depends on the browsers and network route.

I would appreciate honest feedback on reliability, privacy, the pairing flow, and large-file transfers.
