A lightweight, modern desktop utility that prevents your screen from sleeping by simulating mouse movement.
Mouse Jiggler stops the screen going to sleep or the machine locking, by moving the mouse for you. One button to start it, another to stop it, and on with your day.
What it is for
Those stretches where the computer is working but you are not touching it: a long build, a render, a backup, a download. And also when you are at the desk but not on the keyboard — reading a long document, following a presentation, on a call where you are only listening — and the lock screen kicks in at the worst possible moment.
And, of course, to stop that green dot in Teams turning amber while you go and get a coffee. But you did not hear that from me.
Features
- One-click activation — Start or stop the jiggler with a single button press.
- Zen Mode — Invisible cursor movement (±1 px round-trip) that keeps the system awake without any visual disturbance.
- System Tray — Closing the window hides the app to the tray instead of quitting. Right-click the tray icon for Show / Exit.
- Single Instance — Launching the app a second time brings the existing window to the foreground.
- Multi-language — Auto-detects the OS language and supports English, Spanish, French, German and Japanese. Switch manually at any time.
- Windows 11 aesthetic — Dark Fluent Design UI with Segoe UI Variable typography, smooth animations and Lucide icons.
- Tiny footprint — ~2 MB NSIS installer, ~9 MB standalone binary.
