Free Online Mouse Jiggler
A free mouse jiggler online: keep your computer awake straight from your browser. No download, no install, no sign-up — just press Start and your screen stays on.
Runs locally in your browser via the Screen Wake Lock API — nothing is installed and no data leaves your computer. Want to minimize this window? Press Keep Awake When Minimized to pop out a small always-on-top mini-player; your screen stays awake as long as it remains on screen.
What Is an Online Mouse Jiggler?
An online mouse jiggler is a browser-based tool that keeps your computer awake without installing anything. Rather than moving a physical cursor, it uses your browser's built-in Screen Wake Lock API to tell your operating system not to dim, sleep, or lock the screen. You open the page, press Start, and your display stays on until you stop it or close the tab.
That is the whole appeal of running a mouse jiggler online: nothing to download, nothing to install, no sign-up, and no admin rights required. It behaves the same on Windows, macOS, Linux, and Chromebooks, because the logic lives in the browser instead of a native app. If you simply want the screen to stay awake — during a long read, a download, a presentation, or a live dashboard you are watching — this is the fastest way to do it. For an even simpler setup, the free Mouse Jiggler Chrome extension does the same thing from the toolbar — no tab to keep open.
One trade-off matters. A web page cannot move your real mouse cursor or press keys; that is a security rule every website follows. So an online mouse jiggler keeps your screen awake, but it cannot generate the system-level input that apps such as Microsoft Teams, Slack, or a time tracker look for. To keep those showing you as active, you need a desktop app that moves the real cursor. For the full background, see what a mouse jiggler is and how it works.
How the Online Mouse Jiggler Works
The tool uses your browser's built-in Screen Wake Lock API — the same mechanism video sites use to stop your screen from dimming during playback.
Press Start
One click requests a screen wake lock from your browser. No permissions popup, no account, no configuration.
Your Screen Stays Awake
While the jiggler is running, your operating system won't dim the display, start the screensaver, or lock the screen.
Stop Anytime
Press Stop or simply close the tab and your normal power settings take over again instantly. Nothing to uninstall.
Online Tool vs. Desktop App: What's the Difference?
The online jiggler is great for keeping your screen awake. But browsers cannot move your real mouse cursor or type keys — that's a security restriction every website has. For true activity simulation that keeps Teams, Slack, and time trackers showing you as active, you need the desktop app.

How the Screen Wake Lock API Works Under the Hood
The Screen Wake Lock API is a web standard supported by all major browsers. When this page calls navigator.wakeLock.request('screen'), the browser tells the operating system to keep the display on and skip the screensaver, exactly the way a video player does during playback. No cursor movement is simulated, no keyboard events are generated, and no data leaves your computer. The lock is purely a signal from the browser to the OS: "something on screen still needs the display."
The lock is released automatically when you close the tab, navigate away, or press Stop. If you switch to another tab or minimize the browser, most browsers release the lock (since the tab is no longer visible) and re-acquire it when you return. That is why the mini-player exists: a Picture-in-Picture video window counts as visible content, so the wake lock holds even when the main browser window is minimized or behind another app.
Because this is a browser API and not a system-level tool, it has a hard boundary: it can prevent the screen from sleeping, but it cannot generate real mouse or keyboard input. That means apps that check for actual cursor movement or keystrokes, such as Microsoft Teams, Slack, or employee-monitoring tools like Hubstaff and Insightful, will still mark you as idle. For genuine input simulation you need the desktop Mouse Jiggler app. For a fuller comparison of both approaches, see hardware vs software mouse jigglers.
Browser Compatibility
The Screen Wake Lock API is supported in every major browser. The mini-player uses Picture-in-Picture, which has slightly narrower support.
| Browser | Wake Lock (jiggler) | Mini-Player (PiP) |
|---|---|---|
| Chrome 84+ | Yes | Yes |
| Edge 84+ | Yes | Yes |
| Opera 70+ | Yes | Yes |
| Safari 16.4+ | Yes | Yes |
| Firefox 126+ | Yes | No |
| Brave | Yes | Yes |
| Mobile browsers | Most (Chrome, Safari) | Limited |
If your browser doesn't support the Wake Lock API, you'll see an error when you press Start. In that case, update your browser or switch to Chrome or Edge. On Chromebooks, the online mouse jiggler works in the built-in Chrome browser without any special setup.
The desktop Mouse Jiggler app works regardless of browser, since it runs at the operating-system level. It's available for Windows and Linux, with macOS on the way.
Keep your screen on from the toolbar
Love the online jiggler but tired of keeping a tab open? The Mouse Jiggler — Keep Awake Chrome extension uses the same technology, but runs from your browser toolbar. One click to activate, one click to stop — and it works even when all your tabs are closed.
Add to Chrome — It's FreeWhen a Mouse Jiggler Online Is All You Need
If your goal is simply keeping the screen lit, the browser tool is ideal — no install, no device, no footprint. Here is where it fits best.
Keeping the screen awake
Long reads, big downloads, exports and renders, or a task that must not pause when the display sleeps. Press Start and the screen stays on.
Watching something passively
A live dashboard, a monitoring view, or a webinar you are following. The wake lock holds the display without touching your files or settings.
Locked-down or borrowed machines
No admin rights and nothing you are allowed to install? A mouse jiggler online runs entirely in the browser, so there is nothing to set up and nothing left behind.
A mouse jiggler online is the fastest path when all you need is a lit screen. There's no executable to approve with IT, no USB device to explain, and no process running in Task Manager. It's also the simplest option on a borrowed or shared computer since closing the tab leaves zero trace. For a broader look at the benefits of using a mouse jiggler, including the features you get from the desktop app, see the full guide.
But a browser tool has a ceiling. If your company runs activity-monitoring software that tracks real keyboard and mouse events, a screen wake lock won't register as activity. The monitoring dashboard will still show you as idle. For that scenario, you need the desktop app's multi-signal simulation: randomized mouse movement, keyboard input, scrolling, and app switching. Read can your employer detect a mouse jiggler to understand what your specific monitoring setup actually tracks, or compare all your options in best mouse jiggler software.
Need more than a lit screen? To stay shown as active in Teams, Slack, or a time tracker, or to get past idle detection, those read real mouse and keyboard input, which a browser cannot produce. That is the job of the desktop Mouse Jiggler app. Not sure whether it matters for your setup? Read the honest take on whether mouse jigglers actually work or check the detection statistics to see what monitoring tools can actually see.
Online Mouse Jiggler FAQ
Is this online mouse jiggler really free?
Yes. The online mouse jiggler is completely free, with no download, no installation, no sign-up, and no usage limits. It runs entirely in your browser using the Screen Wake Lock API.
How does the online mouse jiggler keep my computer awake?
It uses your browser's built-in Screen Wake Lock API, which tells your operating system not to dim or lock the screen while the tool is running. Nothing is installed and no data leaves your computer.
Does the online jiggler move my actual mouse cursor?
No. Web pages cannot move your real mouse cursor — that is a browser security restriction that applies to every website. The online tool prevents your screen from sleeping, but it cannot simulate system-level mouse or keyboard input.
To keep apps like Microsoft Teams or Slack showing you as active, you need the desktop Mouse Jiggler app, which moves the real cursor.
Will this keep my status active on Teams, Slack, or time trackers?
Not reliably. Those apps detect real mouse and keyboard input at the operating-system level, which a browser tool cannot generate. The online jiggler keeps your screen awake; for genuine activity simulation — mouse movement, keyboard activity, scrolling, and app switching — use the desktop Mouse Jiggler app.
Does the online mouse jiggler work if I minimize the browser tab?
Yes — use the mini-player. Press Keep Awake When Minimized after starting and a small always-on-top window pops out. As long as that mini-player stays on screen, your display stays awake even with the browser minimized or another app in front. Without it, browsers automatically release the wake lock when the tab is hidden and re-acquire it when you return.
The desktop app needs no visible window at all — it runs quietly in the system tray.
Which browsers support the online mouse jiggler?
All modern browsers: Chrome, Edge, Opera, Safari 16.4+, and Firefox 126+. If your browser does not support the Screen Wake Lock API, the tool will tell you when you press Start. The pop-out mini-player works in Chrome, Edge, Opera, and Safari; Firefox supports the basic jiggler but not the mini-player.
Do I need to download anything to use a mouse jiggler online?
No. A mouse jiggler online runs entirely in your browser — there is nothing to download, install, or sign up for, and you do not need admin rights. Open the page, press Start, and your screen stays awake. Close the tab and everything returns to normal.
What is the difference between an online mouse jiggler and a USB one?
An online jiggler is software that holds a screen wake lock in your browser — no device, nothing plugged in. A USB jiggler is a physical dongle that moves the cursor and leaves a hardware trail such as device history in the registry and enumeration logs. They solve different problems: the online tool keeps the screen awake, while a USB device generates real movement. See hardware vs software mouse jigglers and can USB mouse jigglers be detected for the full comparison.
Is an online mouse jiggler detectable?
There is nothing for an activity tracker to flag, because the online tool generates no fake mouse or keyboard input — it only asks the operating system to keep the screen on. That is also the reason it will not keep you shown as active: no input means nothing to detect and nothing to register as activity.
