Features

Seamless Clipboard Sync

Copy text on one device and paste it on another instantly, without any extra interactions. It just works.

Smart File Transfers

ClusterCut handles files intelligently. Small files are sent automatically—just copy and paste. For larger files, you'll receive a notification to download them when you're ready.

Clipboard History

Never lose a clip again. ClusterCut automatically saves your clipboard history, so you can access and paste previous items whenever you need them.

Manual Mode

Don't want to automatically send or receive everything? Enable manual mode to be in full control of your data flow.

Works Remotely

Your cluster isn't limited to one network. Manually add remote clusters to sync over a VPN or the internet securely.

Development

Prerequisites

• Rust & Cargo: Install Rust
• Node.js (v18+): Install Node.js
• Just: cargo install just (or via your package manager)
• Tauri Prerequisites: Follow the Tauri v2 System Dependencies guide for your OS.
  • Linux (Debian/Ubuntu): libwebkit2gtk-4.1-dev build-essential libssl-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev
  • Linux (Fedora/RHEL): webkit2gtk4.1-devel openssl-devel gtk3-devel libappindicator-gtk3-devel librsvg2-devel

Setup

1. Clone the repository:

   git clone https://github.com/keithvassallomt/ClusterCut.git
   cd ClusterCut

2. Install dependencies:

   npm install

Running Locally

To start the development server with hot-reload:

npm run tauri dev

Building

We use a Justfile for all build workflows (requires just):

just build          # Build native package (.exe/.dmg/.deb/.rpm)
just flatpak        # Build and install a local Flatpak from working tree
just run-flatpak    # Run the locally-installed Flatpak
just extension-zip  # Build the GNOME extension ZIP
just release        # Full release: version sync, tag, push, build everything
just clean          # Clean all build artifacts

See BUILD.md for detailed build instructions, Flatpak setup, GNOME extension installation, and the release workflow.

Clipboard Architecture (Linux)

On Linux, ClusterCut uses a three-path clipboard backend:

Environment	Backend
X11	tauri-plugin-clipboard (same as Windows/macOS)
Wayland + KDE/Sway/Hyprland	wl-clipboard-rs via wlr-data-control
Wayland + GNOME	ClusterCut GNOME extension (clipboard bridging over D-Bus)

The backend is detected automatically at startup. On GNOME Wayland, the ClusterCut extension is required for clipboard sync to function.

Recommended IDE Setup

• VS Code + Tauri + rust-analyzer
