IsuDeck by rootcf is a free, high-performance, and open-source desktop studio that repurposes any spare secondary USB keyboard, wireless numpad, or macro keypad into a fully isolated control console.
While commercial macro consoles cost hundreds of dollars with limited physical keys, IsuDeck unlocks 104+ macro keys from hardware you already own with ZERO additional hardware cost.
Standard Windows behavior merges all attached keyboards into one input stream. IsuDeck uses a low-level Interception kernel filter driver to isolate your secondary keyboard by its unique Hardware ID (HID). Keystrokes are swallowed at the OS level before reaching games, documents, or active windows—leaving your main keyboard and gameplay 100% uninterrupted.
Features
- True Hardware Driver Isolation: Isolates secondary keyboards via kernel-level HID filtering so your main keyboard and games are never interrupted.
- Ultra-Lightweight Performance: Built with Rust & Tauri v2, consuming less than 40 MB RAM in the background.
- Extensible Plugin Ecosystem: Develop custom plugins in Python, Node.js, Rust, Go, or C# using JSON-RPC stdio.
- Rich Button Customization: Lucide vector icons, plugin-specific icons, emojis, and custom PNG/SVG background uploads.
- 100% Portable Single Executable: Zero installation dependencies; unpacks and runs cleanly from any folder or USB drive.
