Move text and files between your own devices with a link or a QR code. No accounts.

Paste something on your phone, open the link on your laptop. That’s the whole idea. A drop is controlled by the device that started it, so there’s nothing to sign up for.

A phone uploads to a Rust and SQLite server, which serves a link to a laptop. In private mode the key travels only in the link fragment. paste phone upload Rust + SQLite 24h, then dead link / QR open laptop private mode: the key rides in the #fragment
The server never receives the part of the link after the #.
Server
One Rust binary (axum) with SQLite and files on disk. The pages are plain HTML and JavaScript, compiled into the binary. No build step.
Private mode
Optional. Content is encrypted in the browser with AES-256-GCM before it’s uploaded, so the server stores ciphertext. The key travels in the link’s #fragment, which browsers never send to a server.
Links
128 random bits each, dead after 24 hours, or sooner with one button. Optional password (PBKDF2-HMAC-SHA256, 600,000 rounds). Optional burn-after-reading.
More devices
Get a six-character code or QR, enter it on the other device, and tap Allow on the first one. Until then the newcomer sees nothing.
Big files
Sent in 4 MiB chunks and resumed after a dropped connection, even after a page reload. Up to 100 MB per drop, downloadable as one zip.
Abuse
Turnstile, per-IP and per-device limits, a daily quota and a global disk cap. With no accounts there’s nobody to ban, so the limits have to do the work.
