Stay Awake — Prevent Lock Screen / Sleep
Keeps the screen on using the Screen Wake Lock API. Includes a media fallback. Now installable and works offline.
Status: Idle
Tip: You can install this as an app (PWA) for one‑click use.
How it works
- Click Start Stay Awake (user gesture required by browsers).
- If supported, we request
navigator.wakeLock.request('screen'). - We auto‑reacquire on tab focus/visibility and orientation changes.
- If unsupported/denied, we use a tiny hidden inline media playback fallback.
Offline & Install
- Installs as a PWA via the button above (when eligible).
- Works offline once opened at least once (service worker caches this page).
- On desktop, you can also use the browser menu: Install app.
