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.
