Your backups, kept by people you trust.
Offsite encrypts your files on your own computer and spreads them across your machines and your friends’ spare disk space. No cloud company holds your data — and your friends can’t read a byte of it.
You back up your friends. They back up you.
Choose your folders
Point Offsite at the folders that matter and pick which friends should hold each one.
Sealed on your machine
Every file is split into segments and encrypted before anything goes over the network.
Spread across your circle
Segments travel directly to your friends’ computers, which keep them in space they’ve offered.
Restore from anyone
Lost a disk? Pull your files back from whichever friends are online and rebuild them locally.
Your friends hold your data. They never see it.
Encrypted before it leaves
AES-256-GCM on your own machine. A friend’s disk only ever holds sealed segments with meaningless names.
Direct, peer to peer
Machines connect straight to each other, even behind home routers, over authenticated TLS.
Mirror your own machines
Your laptop and desktop keep plain, ready-to-open copies of each other’s files.
Checked on every write
Every segment is flushed to disk and read back to confirm it landed intact. A damaged copy is simply fetched from the next friend.
Quietly in the background
Starts at login, watches your folders for new, changed and moved files, and keeps the circle balanced on its own.
You choose the circle
Only people you invite and accept can hold your data — and you decide how much space you give them in return.
