MouseUtil is a lightweight Windows utility that keeps your mouse "active" by clicking or jiggling/moving in place, so your PC doesn't go idle, lock, or sleep during long calls, downloads, or AFK sessions. It runs natively on Windows 10/11 (WinUI 3 / .NET 8) with a clean, minimal interface.

Core features

• Two automation modes — Auto click, which sends a real left-click at a set interval, or Spin mode, which sweeps the cursor in a tiny circle and returns it to its exact starting pixel.
• Configurable interval — set the delay between actions in minutes and seconds.
• Pause on manual movement (in 'Spin mode') — if you touch the mouse yourself, MouseUtil automatically pauses and resumes on a fresh countdown once you stop, so it never fights you for control.
• Auto-stop conditions — stop the run automatically after a set number of clicks/spins, or at a specific date and time.
• Global hotkey — start or stop automation from anywhere with a single keypress (F6 by default), even while another app is focused.
• Live status and progress — a real-time countdown ("Clicking in 12s"), action counter, and an optional progress bar mirrored onto the taskbar icon, all of which are optional.
• System tray support — optionally close the window to the tray instead of exiting, so automation keeps running in the background.
• Fluent design with light/dark/system theming.
• Persisted config file, so your interval, mode, hotkey, and preferences are remembered between sessions.

Unsigned installer: Ships as an unsigned .exe installer, so Windows SmartScreen may display a warning the first time you run it.

⚠️ Fair warning: I'm not a software developer. Before starting this project, my coding experience was basic HTML and CSS. This project was developed primarily using Claude Code, with me directing the architecture, reviewing the generated code, testing, and making iterative improvements. All code in this repository has been reviewed before release. The only asset not created with AI is the app icon, which I designed myself.
