How to use the online mouse jiggler
- Leave "Keep the screen awake" on and press Start jiggling.
- Check the status line. "Screen kept awake" means the browser granted the Screen Wake Lock.
- Keep this tab open and in front. You can use other windows next to it, but if you switch tabs or minimize the window, the browser drops the lock until you come back.
- Pick a stop time if you want it to end on its own, or press Stop. The screen then sleeps on your normal timeout again.
Frequently asked questions
Does an online mouse jiggler keep Slack active?
No. Slack sets you away after 10 minutes without input in the Slack window, and a browser tab cannot send input to another app. Keeping the screen awake only prevents the instant away you get when the computer sleeps or locks. To stay green without input, something has to act in Slack for you, which is what Slack Green does from its servers.
Can a website move my mouse pointer?
No. Browsers do not let a web page move the real pointer, for security reasons. Online jigglers, this one included, either animate a cursor inside the page or keep the screen on. This tool does both and says which is which.
How does it keep my computer awake?
It asks the browser for a Screen Wake Lock, a standard web API. While the lock is held, the operating system does not dim or turn off the screen or go to sleep for idle. The lock only lasts while the tab is visible, and it ends when you press Stop or close the tab.
Will it stop my work laptop from locking?
In most setups the screen does not lock for idle while the tab is visible. A lock policy set by IT can still lock it, and battery saver modes can release the lock. The status line tells you when that happens.
Why does it stop when I switch tabs?
Browsers release a screen wake lock when the page is hidden, so a background tab cannot keep a computer on without you knowing. The tool asks for the lock again when you return. Put it in its own window and keep that window uncovered if you work in other apps.
Can IT see this online mouse jiggler?
It creates no mouse or keyboard input, so there is no injected input for monitoring software to flag. The page still shows up in your browser history and in any web filter logs, and a screen that never locks can look odd next to an idle keyboard.
Which browsers does it work in?
Any browser with the Screen Wake Lock API: Chrome and Edge 84 or later, Safari 16.4 or later on Mac, iPhone, and iPad, and Firefox 126 or later. The page must be served over HTTPS, which it is.
