About Supa Transfer

Supa Transfer sends large files and folders straight from one computer to another, even on a different network. Nothing is uploaded first or left on a server, it's end-to-end encrypted, and it picks up where it stopped if the connection drops.

Who makes it

Aura Scale Software makes Supa Transfer: the apps for Mac, Windows and Linux, the supa command line, and this site. Apps for iPhone and Android are coming.

How it's paid for

By Pro subscriptions. Free accounts can send 50 GB and receive 50 GB a month; Pro is $2.99 a month for unlimited sending and receiving. We don't sell your data, show ads, or use analytics trackers.

How it works

Connections use QUIC with TLS 1.3, made with the open-source iroh library, and every byte is checked against a BLAKE3 hash on arrival. The security page has the details, and the privacy policy lists what we keep.
