Simple Tools Should Stay Simple

NoSleepScreen exists for one job: keep screen awake online free when you need a display to stay visible.

Why We Built It

Most people only need a quick way to prevent screen sleep during a presentation, upload, dashboard, call, recipe, or long reading session. NoSleepScreen uses the browser Wake Lock API so you can keep laptop awake without installing software.

What We Value

NoSleepScreen is intentionally lightweight, accessible, privacy-friendly, and fast. The tool is built with plain HTML, CSS, and JavaScript, keeps controls clearly labeled, and does not require an account, browser extension, or file upload.

Trust & Privacy

The wake lock request happens in your browser. NoSleepScreen does not need personal profile data to keep your screen on, and the site includes clear privacy, terms, contact, disclaimer, FAQ, compatibility, and guide pages so visitors can understand how it works before using it.
