Keep Awake
Stop your screen from sleeping
How it works
Uses the browser's Wake Lock API to keep your display on — works on Mac, Windows, Linux, iOS and Android without installing anything. Keep this tab visible; closing or minimizing it releases the lock.
If you close the laptop lid, the OS may still sleep — this only prevents display timeout while the tab is visible.
Prevent your laptop or phone from sleeping. Choose a duration — 15 minutes, an hour, all day — or stay awake indefinitely. Uses the Screen Wake Lock API, works on Mac, Windows, Linux, iOS and Android. No install, no accounts.
Keep Awake is a free tool in the Productivity Tools category on BrowseryTools. It runs entirely in your browser — your data is never uploaded to a server, and there's no registration, no ads, and no watermarks, so your privacy is fully preserved.
