Online mouse jiggler
A free button in this page. It asks the browser to keep the screen on while the tab stays open. That is all it does — and that is all we claim.
This tab only
The screen wake lock is off.

Needs a recent browser and a secure page (HTTPS). Closing, discarding or putting this tab in the background usually releases the lock. JavaScript stays on this site; nothing is sent to a server.
How it works
When you press the button, the page calls the standard Screen Wake Lock API. The browser may then skip turning the screen off because of inactivity in this tab. No mouse movement is sent to Windows. No key is pressed. Teams, Slack and the Windows lock screen are not involved.
If you hide the tab, most browsers drop the lock. We show that honestly and request it again when the tab is visible. There is no hidden video, no loop, and no attempt to look like you are at the keyboard.
What it cannot do
If a site promised the opposite, it was not telling the truth. This tool is not the Windows app.
-
No mouse movement
Windows does not see a cursor move. The idle timer that locks the session is not reset.
-
No session lock prevention
Win+L, a company lock policy, or the usual inactivity lock still apply.
-
No Teams or Slack “available”
Chat apps look at Windows input, not at a browser wake lock. Use the Windows app for that, with the limits described in the Teams guide.
-
This tab only
Other tabs, other apps and a locked PC are unaffected. If the browser suspends the tab, the lock ends.

Questions
Is this a real mouse jiggler?
No. A mouse jiggler simulates mouse input so Windows thinks you used the PC. This page only talks to the browser. The Windows app is the mouse jiggler.
Why did the screen still turn off?
The tab may have been in the background, the browser may not support Wake Lock, or Windows may have locked the session on its own timer. None of that is a bug in the button: the API cannot override them.
Do you collect anything while it runs?
No. The lock lives in your browser. The app itself never connects to the internet; this website only counts a download if you click a download button.
