What Does the Mouse Jiggler App Do?

Mouse Jiggler keeps your computer active by simulating natural, randomized input. Unlike a basic cursor mover or a USB dongle, it covers every signal that monitoring tools and status indicators track: mouse movement with varied speed and direction, keyboard activity, scrolling, browser tab switching, and app switching. The app runs from the system tray with zero visual footprint and starts automatically when you go idle.

Everything runs locally on your machine. No data is collected, no usage is tracked, and the app never contacts a server except to verify your subscription and check for updates. For a complete walkthrough of every feature, see the documentation. For the honest take on what this app can and can't do against monitoring software, read can your employer detect a mouse jiggler.

Why Portable?

Mouse Jiggler ships as a single portable executable on both platforms — a .exe on Windows, an AppImage on Linux. No installer, no system folders, no registry modifications, no services or daemons. You can run it from a USB drive, move it between computers, or delete it by dragging the file to the trash. This matters on managed machines where software installs are locked down or monitored: a portable app that doesn't write to system directories has a much smaller footprint than a traditional installer. When you're done, it leaves nothing behind.

If you just want to keep the screen awake without downloading anything, the free online mouse jiggler runs entirely in your browser. It won't simulate real input, but it prevents sleep and screensaver with zero installation. For a comparison of all the available tools, see best mouse jiggler software.
