Pyx is going global
Soon you'll be able to send files to anyone over the internet — the same direct, encrypted, peer-to-peer transfer, no longer limited to your local network.
Skip the cloud upload. Skip the USB stick. Just drop it across the room.
Built for moving real files, fast
Everything you need to shuttle builds, dumps, and assets between machines — without a USB stick or a cloud upload.
End-to-end encrypted
Every transfer runs over an encrypted QUIC (TLS 1.3) connection, with a per-file BLAKE3 integrity check. Nothing crosses the wire in the clear.
Zero configuration
Open Pyx on two devices and they discover each other automatically over the local network. No IP addresses, pairing codes, or accounts.
Full LAN speed
Files stream disk to disk, directly between machines — no cloud upload, no relay, no round trip.
Files & folders
Send one file, a dozen, or an entire directory tree — the structure is recreated exactly on the other side.
Private by design
The receiver approves every transfer before a byte is written, and your files never leave your own network.
Always up to date
Built-in signed auto-updates keep every install quietly current — no manual reinstalling, ever.
Three steps. No accounts.
From install to first transfer in under a minute.
