Keep Awake
Prevent your laptop or phone from sleeping. Pick a duration or stay awake indefinitely. Runs on your device — nothing is uploaded, nothing is stored.
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.

Keep Awake is a free tool in the Productivity category on BrowseryTools. It runs entirely in your browser: what you give it is processed on your own device and is never uploaded to a server, there's no registration, no ads and no watermarks, and it keeps working with no connection once the page has loaded.
