Stay Awake
Idle
Important: this page must stay on top
- Keep this tab/app in the foreground. Most browsers pause background tabs, so “keep alive” events can stop when you switch away.
- If your goal is to keep the screen on, Wake Lock works best when the page remains visible (especially on mobile).
- On laptops, OS features like Battery Saver or power policies may still dim/lock the screen.
- Tip: Use this in a dedicated window and keep it on top, or install it as an app (button appears when supported).
Status
- Mode: Not running
- Wake Lock: Not requested
- Keep-alive tick: —
- Interval:
10 seconds
This tool prevents system sleep by requesting a Screen Wake Lock (when supported) and running a small keep-alive loop.
If you switch apps/tabs, your browser may throttle timers and the keep-alive loop may pause — that’s normal browser behavior.
