Your clipboard,
in sync. Across your Macs.

TandemClip shares your clipboard between your Macs over the local network — copy on one, paste on another. End-to-end encrypted with a code only you hold. No cloud, no account, nothing ever leaves your network.

How it works

Two Macs, one clipboard —
or pull a specific one on demand.

Mirror mode

Copy anywhere and it appears everywhere. Deduped, loop-safe, and it relays across machines that can't see each other directly.

Manual mode

Keep each Mac's clipboard its own. From the menu bar, pull the clipboard from a specific Mac when you want it.

Roles & trust

Make a machine send-only or receive-only, and restrict sync to a trusted-device allowlist.


Private by design

Your clipboard never leaves your network.

No cloud, no relay

Peers talk directly over your LAN. There is no server, no account, and nothing to breach.

Password-manager safe

Content marked secret by 1Password and others is never synced. Same for one-time and transient copies.

A code only you hold

A shared pairing code becomes the encryption key. Being on the same Wi-Fi grants nothing on its own.


Copy here. Paste there.
