Your clipboard, everywhere on your LAN.
A lightweight native app that syncs text, images, and files across your Mac, PC, and Linux box — and lets you share one mouse and keyboard between them. Instant, encrypted, and without the cloud.

macOS 13+ · 64-bit Windows 10/11 · Linux (Flatpak) — free & open source, no account required.
- 🔄 LAN clipboard sync — copy on one machine, paste on another, instantly.
- 🖼️ Text & images — synced automatically, no manual steps.
- 📁 Click-to-sync files — copy files, choose Send Files from Clipboard, paste on the other device.
- 🖱️ Mouse & keyboard sharing — one mouse and keyboard for all machines, with a drag-based screen layout.
- 🎯 Auto control device — control follows whichever physical mouse or trackpad you touched last; keyboard activity never switches it, so a mouse on one machine and a keyboard on another just work.
- 🚇 Port forwarding — tunnel SSH, VNC, or a dev server between devices over the same encrypted connection.
- 🕓 Clipboard history — browse and reuse recent clipboard items with thumbnails.
- 🔐 Private by design — password-authenticated, encrypted payloads; no account, no cloud.
- ⚡ Fully native — Swift on macOS, C# on Windows, Qt/C++ on Linux. No Electron.
- ⟳ Auto-updates — built in on all three platforms.

Built-in port forwarding: reach a service on any of your devices as if it were local.
