Mouse Jiggler is a lightweight Windows utility designed to simulate minor mouse movements automatically, preventing the computer from entering sleep mode, locking, or triggering a screensaver. It is useful for scenarios where users need to keep the system active without physically interacting with the mouse, such as during long downloads, presentations, or remote monitoring sessions. The tool runs quietly in the background with minimal resource consumption and does not interfere with normal user activity. Some versions offer “Zen mode,” which simulates movement invisibly without moving the on-screen pointer. Mouse Jiggler is simple, portable, and free, making it a convenient solution for maintaining an active system without manual intervention.
Pros and Cons
Pros:
Prevents the system from going idle or triggering screensavers automatically.
Extremely lightweight and portable—no installation required.
Minimal CPU and memory usage during operation.
Offers “Zen mode” to simulate movement without visible pointer motion.
Useful for long processes like downloads, updates, or remote desktop sessions.
Free and easy to use with no complicated setup.
Compatible with most Windows versions, including Windows 7, 8, 10, and 11.
Cons:
Limited functionality—only simulates mouse movement and cannot prevent sleep through other settings.
May be detected as suspicious by security software if used improperly.
Not designed for automation beyond preventing idle mode.
Users must manually start or stop the tool; no built-in scheduling.
Does not work on non-Windows operating systems.
Key Features
Simulates small, continuous mouse movements to prevent idle detection.
“Zen mode” option to keep cursor stationary while still tricking the system.
Runs in the background with minimal resource usage.
Portable and requires no installation, making it easy to run from USB drives.
Simple toggle interface to start or stop the simulation instantly.
Compatible with most Windows versions and works with multiple monitors.
Freeware with no ads, pop-ups, or unnecessary background processes.
Lightweight executable, typically under 100 KB, for fast launch and minimal disk space usage.
Functions
Prevents screensavers from activating by simulating mouse movement.
Keeps the computer active during long tasks, downloads, or remote sessions.
Maintains active session for remote desktop connections to avoid disconnection.
Works invisibly in Zen mode for situations where pointer movement is undesirable.
Provides a toggle mechanism to quickly start or stop the simulation as needed.
Helps users prevent automatic screen locking due to inactivity.
Ensures background processes are not interrupted by idle triggers.
Supports multiple monitor setups, keeping the system active on all displays.
Serves as a simple productivity tool for IT administrators or remote workers.
Runs offline without requiring internet access or external dependencies.
How to Use
Download Mouse Jiggler from a trusted source and extract the executable file.
Run the program directly; no installation is required.
Check the box to enable mouse jiggling and start the simulation.
Optionally, enable “Zen mode” to keep the on-screen cursor stationary.
Let the program run in the background while performing other tasks on your computer.
To stop simulation, uncheck the box or close the application from the system tray.
Keep the executable in a convenient folder or USB drive for portable use.
Use the tool during downloads, presentations, remote sessions, or any scenario where you need to prevent idle mode.
Verify system activity by checking that screensavers or sleep mode do not trigger while the tool is active.
Close the program once continuous system activity is no longer required.
