Mouse mover vs mouse jiggler: what is the difference?

Same goal, different words

A mouse jiggler and a mouse mover both simulate activity so the computer does not go to sleep, turn off the screen or lock the session. In practice:

• “Mouse jiggler” usually means a tool that makes a tiny back-and-forth movement, sometimes with no visible movement at all.
• “Mouse mover” is often used for tools that move the cursor over larger distances, or that add clicks and keystrokes.

Software mouse jigglers

A program sends simulated input events to Windows at regular intervals.

• Pros: free in most cases, adjustable (interval, mode), can be turned on and off with a shortcut or scheduled.
• Cons: it has to be installed or launched, and it is visible in the task manager.

Mouse Jiggler is in this category: Classic mode (a movement of a few pixels that comes straight back) or Zen mode (activity with no cursor movement), automatic stop, scheduled lock, and no administrator rights.

Hardware (USB) mouse jigglers

A small USB device that the computer sees as a mouse. It sends real movements, with no software to install.

• Pros: nothing to install, works on any operating system that accepts a USB mouse.
• Cons: it costs money, it occupies a port, it usually cannot be scheduled, and you have to unplug it to stop it. Many models move the cursor visibly.

Advanced mouse movers

Some tools go further: clicks, key sequences, scripts, complex schedules. They are useful for automation, but more complex to configure than a simple jiggler.
