Mouse jiggler · guide

Move your mouse automatically

A mouse jiggler simulates activity so the screensaver never kicks in, your device never sleeps and nothing marks you away. KeepOnDuty does it in software.

What it is

Hardware vs software

There are hardware mouse jigglers (a USB gadget or a pad that physically moves the mouse) and software ones (an app that moves the cursor for you). Hardware ones cost money, take a port and some corporate setups flag new USB devices.

KeepOnDuty is software: free, nothing to plug in, and full control over intervals, schedules and patterns. And unlike a browser jiggler, it works at system level, so it covers all your apps.

What it's for

Everyday, legitimate uses

Stop the screensaver during presentations or demos.
Keep long downloads, builds or renders alive.
Stay “available” on Teams, Slack or Discord while you read or think.
Keep the machine from sleeping while you monitor something.

Features

Everything you'd expect from a mouse jiggler

Real movement

Moves the mouse at the operating-system level, not a fake cursor. Resets the inactivity timer for every app at once.

Schedules & work hours

Set your work hours (9–6, Mon–Fri) with simple schedules or cron. Blackouts for your breaks.

Stealth mode

Imperceptible micro-movements, random patterns and adjustable speed for natural behaviour.

Respects your activity

The moment you touch the mouse it steps aside; when you leave, it resumes on its own.

Private & local

Sends nothing to any server. Works 100% offline; everything stays on your device.

Free, no account

No sign-up, no cost, no ads. Download it, press Start and you're done.

Compatibility

Works with the apps you use every day

No integrations, no weird permissions. KeepOnDuty works at the operating-system level, so any app that tracks inactivity keeps seeing you active.

…and any presence-aware app

FAQ

Frequently asked questions

What is a mouse jiggler and what is it for?

It's a tool that moves the mouse periodically to simulate that you're still using the device. It's used to avoid sleep, the screensaver and “away” statuses.

Is a software or hardware mouse jiggler better?

Software is free, more configurable (schedules, patterns) and doesn't use a USB port. Hardware can work without OS permissions, but it costs money and some machines detect the device.

Does a mouse jiggler stop me being marked away?

Yes, if it generates real mouse movement (like KeepOnDuty), because it resets the system idle counter that Teams, Slack or Discord rely on.

Is KeepOnDuty free?

Yes, free, no sign-up and no ads, for Mac and Windows.
