Best free mouse jiggler software (2026)
Mouse jiggler software is one of those categories where free options are genuinely excellent — there's rarely a reason to pay. The trick is picking one that's lightweight, safe, and behaves naturally. Here's what matters and which tools deliver.
What to look for in a free mouse jiggler
- Randomized movement. Fixed, perfectly-timed jiggles look robotic. Randomized timing and distance behave more like a real hand.
- An instant on/off toggle so you can pause it the moment you need the mouse.
- Small, unobtrusive motion — tiny nudges that reset the idle timer without dragging your cursor across the screen.
- Lightweight and clean — a single small app with no bundled junk, easy to remove.
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.
