Doze – Tab Sleeper

Doze quietly puts tabs and windows you haven't touched in a day to sleep: a sleeping tab is parked on a tiny Doze page and unloaded, so its memory is really released. Sleeping tabs stay exactly where they are in your tab strip and spring back to the original page the moment you click them. Nothing is lost, nothing moves. Why Doze • Zero setup. Install it and it just works. Default delay is 1 day. • Zero overhead. No content scripts, no background page that stays alive, no network. One quick check every 15 minutes. • One tiny popup. Pick the delay (12h, 1 day, 2 days, 3 days, 1 week), choose whether pinned tabs are skipped, keep specific sites awake, or sleep everything right now. • Smart defaults. The tab you're looking at, pinned tabs and tabs playing audio are never put to sleep. Whole windows you haven't focused for a day sleep too. • Private by design. Nothing leaves your browser. No accounts, no analytics, no tracking.
