Why Use a Browser-Based No Sleep Page?
Whether you are monitoring an AI coding session, delivering a presentation, or preventing aggressive 3-minute corporate timeouts, a web-based no sleep page gives you temporary control without changing permanent operating system settings.
Zero Installation
No .exe installers, no browser extensions, and no app store accounts required. Works instantly in Chrome, Safari, Edge, and Firefox.
Safe for Work Laptops
Runs with standard browser permissions. Unlike physical USB mouse jigglers, it does not trigger enterprise EDR or MDM security alerts.
Custom Timers
Choose 15m, 30m, 1h, 2h, or specify custom hours. The wake lock automatically releases when the timer expires to prevent battery drain.

Frequently Asked Questions
What is a no sleep page?
A no sleep page is a lightweight web tool that uses your browser’s native Screen Wake Lock API to prevent your monitor, laptop, or mobile screen from dimming, locking, or going into sleep mode. It requires no downloads, no browser extensions, and no system configuration.
How do I use this no sleep page?
Simply click the large power button above. As long as you keep this browser tab open and visible, your display will remain illuminated. You can set a countdown timer (such as 15m, 30m, 1h, 2h) or leave it set to "No limit".
Does this no sleep page require administrator privileges?
No. Because it runs entirely inside standard web browsers (Chrome, Edge, Safari, Firefox), it uses standard web platform permissions and does not require administrative or root credentials. It is safe for corporate laptops and IT-managed devices.
Is this safer than a USB mouse jiggler for work laptops?
Yes. Enterprise endpoint detection software (EDR like CrowdStrike, Microsoft Defender for Endpoint, and Tanium) frequently monitors and flags unauthorized USB hardware IDs from physical mouse jigglers. A no sleep page simply asks the operating system to postpone display sleep while a web tab is active, leaving zero unauthorized driver or hardware footprints.
How is this different from legacy tools like William Tan’s NoSleep?
Older keep-awake websites (such as NoSleep.js) relied on playing invisible, muted MP4 video loops in the background, which wasted battery and CPU cycles. Our no sleep page uses the modern W3C Screen Wake Lock API, which is native, lightweight, and releases cleanly as soon as the tab is closed.
Does it work on iPhone, iPad, and Android?
Yes. Starting with iOS 16.4 and iPadOS 16.4, Apple added native Screen Wake Lock support to Safari. Android Chrome has supported it since version 84. Simply open this page on your phone or tablet and toggle it on.
