How to use the online mouse mover
- Choose an auto-stop if you want one: a fixed duration, a custom number of minutes or a clock time. Leave it on “No limit” to run until you press Stop.
- Press Start. The status changes to “Screen kept on” when the browser grants the wake lock.
- Keep this tab visible. You can work in another window next to it, but if you minimise the browser or switch to another tab, the browser pauses the lock.
- Come back to the tab and the lock is requested again automatically (you can switch this off). Every pause is listed under Interruptions, so you can see whether the screen was really protected.
- Press Stop or let the timer end. Your normal screen timeout applies again immediately.
Your choices (duration, custom minutes, automatic resume) are saved in this browser only. If the page reloads during a session, it offers to resume it.
Mouse mover, mouse jiggler or keep-awake: what this page really does
A classic mouse jiggler or mouse mover produces input: a USB device that reports tiny movements, a program that moves the pointer, or a mechanical stand that physically moves the mouse. A web page cannot do that. Browsers do not let a website move the system cursor or press keys, and this tool does not pretend to.
What a page can do is ask for a screen wake lock. The Screen Wake Lock API prevents the screen from turning off, dimming or locking while the page is visible[1]. That covers the most common reason people search for an online mouse jiggler: a screen that goes dark while they read, present, follow a dashboard or wait for a download.
| Method | Keeps the display on | Creates mouse input | Install needed |
|---|---|---|---|
| This tab (wake lock) | Yes, while the tab is visible | No | No |
| Phone jiggler with an optical mouse | Phone screen yes; computer only if the mouse input counts | Yes, if the sensor reads the pattern | No |
| USB or mechanical jiggler | Yes, as a side effect of input | Yes | Hardware |
| System settings (Windows, Mac) | Yes, until you change them back | No | No |
If you are not sure which approach fits your case, the comparison of mouse jiggler alternatives goes through installation, input and screen behaviour one by one.
When the screen can still turn off
- The tab is hidden. Browsers release the lock automatically when you minimise the window or switch away from the tab[2]. The status shows “Paused” and the event is logged.
- Battery saver or low battery. The browser may refuse the request; MDN lists low battery among the reasons for a
NotAllowedError[3]. - Unsupported browser. The API is available in Chrome and Edge 84, Firefox 126 and Safari 16.4 or later[2]. Older versions get a clear “Not supported” message instead of a false green light.
- Not on https. The API only works on secure pages[1].
- Device policies. A work computer can enforce a lock after a fixed time. A browser tab cannot override that, and should not.
The wake lock is about the display. It does not promise that the computer will not sleep for other reasons, and it does not keep the screen on at the lock screen. If the screen still turns off, the troubleshooting guide walks through each layer.
Will it keep Teams or Slack green?
Not by itself. Teams and Slack decide your presence from activity, not from whether the screen is lit. Microsoft documents that Teams shows you as Away when the desktop is inactive for more than five minutes[4], and Slack sets you to away after 10 minutes of desktop inactivity[5]. A wake lock does not create keyboard or mouse activity, so it does not reset those timers.
The guides for Teams and Slack explain the documented settings that do affect presence, and why a status can still change while you are working.
Using it on a work computer
Because nothing is installed, the tool works on many laptops where you have no admin rights. That does not make it invisible: your browser history, the network and management software can still record that you opened this site. The guide on whether mouse jigglers can be detected explains what is observable for each type of tool. Check your employer's rules before using any keep-awake method on a managed device.
Free, no download, no account
The tool runs entirely in your browser. There is no sign-up and no server-side processing: the timer, the status and the interruption log never leave your device. Preferences are stored in your browser's local storage so they are there next time; clearing site data removes them.
Frequently asked questions
Does this online mouse jiggler move my cursor?
No. Websites cannot move the system cursor. This page keeps the display awake with the browser's screen wake lock. For real mouse input without installing software, try the phone jiggler with an optical mouse.
Can I minimise the window?
Minimising or switching tabs makes the browser release the wake lock[2]. Keep the tab visible, for example in a small window beside your work.
Is it really free and without download?
Yes. It is a web page: no installation, no account and no payment. The site may show ads once advertising is enabled; they are never placed inside the tool.
Why does the status say “Not supported”?
Will my computer stay awake if the screen is kept on?
Usually the system does not go to sleep while the display is in use, but the API only promises to keep the screen on. For long downloads or renders, follow the checklist in the guide on preventing sleep during long tasks.
