Our picks

1. Mouse-Jiggler.io (our free tool)

Naturally, we're partial to our own free jiggler: randomized, human-like movement, a browser control panel to flip it on and off, and no installer — just download and double-click. There's also an in-browser keep-awake tool if all you need is to stop the screen sleeping.

2. Move Mouse

A popular open-source Windows app with schedules and "blips." More configurable, though heavier than a simple jiggler and Windows-only via the Microsoft Store.

3. Caffeine (and Amphetamine on Mac)

Classic tiny utilities that keep the machine awake by simulating a keypress. Dead simple, though older and less about randomized movement.

When free software isn't enough

Free software is the right answer for most people. The main exception is a locked-down work laptop that blocks unapproved apps — there, a USB hardware jiggler works with no software to install. And remember: any software jiggler is a process on your PC, so if you're worried about advanced monitoring, read are mouse jigglers detectable? first.

Bottom line

Start free — a good randomized jiggler costs nothing and covers the vast majority of needs. Only reach for paid hardware when software is blocked or you specifically want zero trace on the machine. Grab our free tool here to try it in seconds.
