https://screenwakeup.com — a free web page that keeps your screen awake. One click, no download, no account, no ads.
It does one honest thing: it asks the browser for a Screen Wake Lock so your screen doesn't dim, sleep or lock while the tab stays visible. It does not simulate mouse or keyboard input — browsers can't, and the site says so. Sites that promise otherwise are selling the same wake lock with a false label.
- Keeps the screen on with the native Wake Lock API, with a silent-video fallback for browsers without it.
- Presets (30 min, 1 h, 2 h, 4 h, unlimited) or any number of minutes.
- Pomodoro timer, fullscreen clock, floating mini-window (Picture-in-Picture) for when you work in other apps.
- Dark and light mode, 7 languages (EN, ES, PT, FR, DE, JA, RU).
- Honest limits, stated in the FAQ: the lock is released when the tab is hidden or the OS enforces battery saving.
- Prevent the Away status in Microsoft Teams
- Free Caffeine alternative for Mac and Windows
- Keep the iPhone screen awake without touching Auto-Lock
- Keep Zoom active
