A macOS menu-bar app for encrypted, peer-to-peer clipboard sharing across Macs on the same network. No server, no account — devices sharing a secret key find each other over Bonjour and sync text, images and files with AES-GCM encryption.
MultiClip is a macOS menu-bar app for peer-to-peer clipboard sharing across Macs on the same network — without needing the same Apple ID on every machine (the whole reason it exists).
Key features
- True peer-to-peer — devices discover each other over Bonjour; no server, no account
- Encrypted and key-gated — AES-GCM with keys derived (HKDF-SHA256) from a shared secret; a device with the wrong key can't decrypt a single frame
- Copy → announce — only metadata (preview, size, file list) is broadcast; the bytes stay put until you ask
- Never auto-pastes — incoming items appear in the menu and only land on your clipboard when you pick them
- Lazy transfer with file support up to a configurable size limit, plus completion notifications for files
- History — the last 5–50 local copies persist across restarts
- Global hot key (default ⌘⌥V) pastes the most recent remote item into the frontmost app
Supports plain text, rich text, images and files. Requires macOS 13+.
