One clipboard, every PC.
Stop AirDropping to yourself, emailing files to your own inbox, or pasting into a Slack DM just to move something between your own computers. Infinite Clipboard keeps every PC you own — Windows, macOS, Linux — in sync automatically, over your own Tailscale network.
- 📋 Instant text sync — copy on one PC, it's already on the clipboard of every other connected PC
- 📁 On-demand file & folder transfer — copying just makes a file available; it only transfers when you actually paste it elsewhere, so idle PCs never get clogged with data they don't need. Interrupted transfers resume automatically
- 🖼️ Images sync too — screenshots and copied images work the same way
- 🔒 Private by design — travels over your own Tailscale (WireGuard) network, gated by a shared key — no cloud service sits in the middle
- 🖥️ Lives in your tray — set it up once on each PC, forget it's running
Download the package for your OS from the GitHub Releases page. Every PC's auth_key must match exactly (see "Share the key once" below).
| OS | File (X.Y.Z = version) | Install |
|---|---|---|
| Linux (Arch/CachyOS) | infinite-clipboard-X.Y.Z-1-x86_64.pkg.tar.zst |
sudo pacman -U <file> |
| macOS (Apple Silicon, M-series) | Infinite.Clipboard.X.Y.Z-apple-silicon.dmg |
Open the DMG → drag to /Applications → Gatekeeper bypass required, see below |
| macOS (Intel) | Infinite.Clipboard.X.Y.Z-intel.dmg |
Same as above |
| Windows | infinite-clipboard-setup-X.Y.Z.exe |
Run the installer and follow the prompts (per-user, no admin rights needed) |
After installing:
- Linux: Application menu → Infinite Clipboard
- macOS: Launchpad, or
open "/Applications/Infinite Clipboard.app". Run the Gatekeeper bypass below first or it won't launch - Windows: Start menu → Infinite Clipboard (you can check "start automatically" during install)
The DMG isn't code-signed, so macOS quarantines it ("Apple could not verify this app is free of malware..."). Clear the quarantine flag once with:
xattr -dr com.apple.quarantine "/Applications/Infinite Clipboard.app"After that it runs and auto-starts like any normal app. You'll need to re-run this command once whenever you overwrite it with a new version.
Right-click → Open doesn't reliably work around the block on unsigned builds (Apple Silicon or Intel) — the
xattrcommand is the reliable fix.
On first launch, each PC generates its own random auth_key. For PCs to connect to each other, they all need the same key.
1. Launch the app on PC A → auth_key is generated in that PC's settings.json
2. Copy PC A's auth_key value
3. Paste the same value into auth_key in the other PC's settings.json + restart the app
(or type it directly into Tray → Settings → Auth Key)
Settings file locations:
| OS | Path |
|---|---|
| Linux | ~/.config/InfiniteClipboard/settings.json |
| macOS | ~/Library/Application Support/InfiniteClipboard/settings.json |
| Windows | %APPDATA%\InfiniteClipboard\settings.json |
- Text sharing: Ctrl+C on any PC → syncs instantly to every connected PC, no extra steps
- File/image transfer (lazy): copying a file/folder/image just notifies the other PCs that something is available — the actual transfer only starts when you press Ctrl+V on that PC, or click "Receive" in the tray's Transfers window (copying alone never auto-transfers). Once complete, it's saved to
~/Downloads/(or your configured path) - Settings: right-click the tray icon → Settings
- History: right-click the tray icon → Clipboard History
- Transfer progress / receiving: right-click the tray icon → Transfers
- Autostart: toggle "Start automatically" in the settings window
- Updates (v3.0.14+): the app checks GitHub for a new release 30 seconds after it starts and then once a day. When one is out, the tray menu shows Install Update (vX.Y.Z) — one click downloads it, verifies its SHA-256 checksum, installs it, and restarts the app. You can also use Check for Updates in the tray menu at any time, or turn off the automatic check in the settings window

(WireGuard encryption)
- One fixed server PC, the rest are clients
- Tailscale's WireGuard handles encryption — there's no additional app-level encryption
- Clients auto-reconnect if the server restarts (5s interval by default)
- Default port
9999
Works out of the box in most setups if you're only using Tailscale. For a direct LAN connection:
# Linux (ufw)
sudo ufw allow 9999/tcp
# Windows PowerShell (as Administrator)
New-NetFirewallRule -DisplayName "Infinite Clipboard" -Direction Inbound -Protocol TCP -LocalPort 9999 -Action Allow
# macOS
# System Settings → Network → Firewall → allow InfiniteClipboardGatekeeper is blocking the ad-hoc signed app. Right-click the .app in Finder → Open, once, and it'll launch normally after that.
Make sure every PC's auth_key matches exactly — a single character off will fail. The most reliable fix: copy the server PC's settings.json and overwrite it on the client PCs.
Automatic resume is built in. Restart the app and it'll pick up from the checkpoint (~/.config/InfiniteClipboard/checkpoints/ or the equivalent settings folder per OS). If resume also fails, manually delete the temp directory (e.g. /tmp/ic_transfer_<id>/) and retry the transfer.
Happens because there's no proper code-signing certificate. Click "More info" → "Run anyway". If you need code signing, buy a certificate and sign with signtool.
From v3.0.14 on, update from the tray menu (Install Update (vX.Y.Z), or Check for Updates first). If you're on v3.0.13 or older, install v3.0.14 manually once — the updater ships inside the app, so older versions don't have it.
- Windows: installs silently and relaunches the app. If you installed "for all users" (Program Files), the installer opens normally instead so Windows can ask for permission
- Linux (Arch package): a system password prompt appears once (the package is installed with
pacman -U). If you cancel, the current version simply starts again - macOS: the app in
/Applicationsis replaced and relaunched — no quarantine command needed for updates - The update is refused while a file transfer is in progress. Files waiting to be received stay in the Transfers window after the restart (v3.0.17+)
- Running from source, or installed somewhere the app can't write to? The menu item opens the release page instead
- The installer's log is
update-helper.lognext to the app's log file; after restarting, the app tells you whether the update was installed
