One folder, the same
on all your computers.
Pairnets keeps a folder identical on your computers through a small server you own. Your files never go to someone else's cloud.
Other systems: Mac (Apple silicon) · Mac (Intel) · Linux · Windows (no installer)
Pairnets is for computers for now. A phone app will use the same sign-in.
Three steps
Get the app
Install Pairnets on the computer. It lives in your tray or menu bar and keeps one folder in sync.
Sign in with your browser
Type your nest's name and press Sign in. Your browser opens your nest; you check a code and press Allow. No server addresses or secret tokens to copy.
Pick a folder
It catches up with your other computers, then stays in sync. Switch computers any time.
Built to keep your files safe
Yours, not ours
The server is a small program on a machine you own, reached through a Cloudflare Tunnel — no ports to open. Only computers you have approved get in. This website never sees your files.
Never overwrites silently
If two computers change the same file, both versions are kept. Every overwritten or deleted file stays on your server for 30 days.
One key per computer
Lost a laptop? Remove just that computer from your nest and its key stops working at once. Nothing else changes.

Your server (your nest)
Any always-on Ubuntu machine. Make a free Cloudflare Tunnel for its name, then one command:
