About Mouse-Jiggler.com
Mouse-Jiggler.com is a free, browser-based tool that keeps a computer registering activity, so the screen does not dim, sleep, or lock while you are still using it. Alongside the tool we publish guides about sleep settings, presence indicators, and working on locked-down hardware.
Who runs this site
The site is owned and operated by Güven Aydın, an independent software developer based in the Netherlands. It is a small, self-funded project rather than a company product, which means there is one person responsible for the code, the writing, and any mistakes in either. If something on the site is wrong, out of date, or unclear, writing to us actually reaches the person who can fix it.
You can reach us through the contact form. We read every message and generally reply within a few working days.
Why the site exists
The idea came from a mundane problem. Corporate laptops are often configured to lock after a few minutes of no keyboard or mouse input. That policy makes sense for security, but it treats "no input" as "nobody is there", which is frequently wrong: you can be reading a long document, watching a training video, presenting to a room, monitoring a build, or waiting on a two-hour render, and the machine will still decide you have left.
Every existing fix had a catch. Hardware jigglers cost money and register as unknown USB input devices, which many IT departments block on principle. Desktop utilities require an installation, and on a managed device you often do not have the rights to install anything - or the software gets flagged by endpoint protection. Changing the power settings themselves is usually locked by group policy.
A web page has none of those problems. It runs inside a browser tab that is already open and already trusted, it installs nothing, and it changes no system configuration. So we built one.
How the tool works
An optical mouse contains a tiny camera that photographs the surface beneath it several thousand times a second. Firmware compares consecutive frames, works out how far the image shifted, and reports that as cursor movement. It does not care whether the surface is a desk or a screen - it only needs a visible pattern that moves.
Our page draws a moving grid on an HTML5 canvas. Rest an optical mouse on a phone displaying that grid, and the sensor sees the pattern sliding underneath it and reports genuine movement to your computer. From the operating system's point of view, a real mouse moved, because one really did. We explain the mechanism in more depth in how optical mouse sensors work.
What we do not do
- We do not install anything on your computer, and we never ask you to download an executable.
- We do not read your files, detect your installed software, or inspect your network.
- We do not require an account, an email address, or any personal detail to use the tool.
- We do not sell personal data. Details are in our privacy policy.
The tool is also not a way to misrepresent your working hours, and we do not present it that way. Whether a jiggler is acceptable on a device your employer owns is a question for your own IT and HR policies, and the answer varies between organisations. We would rather say that plainly than pretend the question does not exist.
Editorial standards
Everything published here is written specifically for this site. We do not republish content from elsewhere or pass off generated filler as a guide. Our rules for articles are simple:
- Test before publishing. Setting paths, menu names, and command syntax are checked on the relevant operating system version before an article goes live.
- Name the trade-offs. If a method has a downside - battery drain, thermal risk, a policy that overrides it - the article says so.
- Say when something will not work. Several of the guides here end by telling you that a particular approach cannot solve your problem. That is more useful than a workaround that fails silently.
- Date everything. Every article shows its publication date so you can judge how current the instructions are. Operating systems move menus more often than anyone would like.
How the site is funded
The tool is free and has no paid tier. Running costs are covered by advertising and, in some articles, affiliate links to hardware we describe. Advertising never influences which guides we write or what conclusion an article reaches - including when the honest conclusion is that a product is not worth buying. Any affiliate relationship is disclosed on the page where it applies and in our disclaimer.
