Tab Hibernator Pro

Automatically suspends inactive tabs to free RAM. Smarter, faster, and privacy-first.

Tab Hibernator Pro — automatically free up RAM from tabs you're not using. Too many open tabs slow Chrome to a crawl. Tab Hibernator Pro quietly suspends the tabs you've stopped using and frees the memory they were holding — then brings them back exactly where you left off, the moment you need them. No tab loss. No setup. No tracking. ★ KEY FEATURES • Automatic hibernation — inactive tabs are suspended after a timeout you choose (5 minutes to 4 hours). • Smart exclusions — tabs playing audio, pinned tabs, tabs with unsaved form input, and your active tab are never touched. • Whitelist — keep specific sites awake forever (exact domain and sub-domain matching). • Smart Memory mode — hibernates faster automatically when your system RAM runs low. • Battery Saver mode — only hibernate while on battery power. • One-click controls — Hibernate All / Wake All right from the toolbar popup. • Quick-Wake search (Ctrl+Shift+K) — instantly find and restore any tab. • Restore on focus — optionally wake a tab the moment you click it. ★ DEEP SLEEP STASH Go beyond hibernation. Stash tabs to close them completely and save them for later: • Stash Tab — tuck away a single page. • Stash Group — save an entire Chrome tab group (name, color and all tabs) and restore it intact. • Stash All — clear every suspended tab at once for a fresh start. Everything reopens from the Stash Board in your dashboard whenever you want. ★ ANALYTICS DASHBOARD A clean dashboard shows estimated memory saved, tabs suspended over time, your top hibernated sites, and a 7-day activity chart — plus a built-in guide to using stashing effectively. ★ PRIVACY FIRST • No accounts, no tracking, no analytics sent anywhere — everything stays on your device. • Optional tab previews are OFF by default; no screenshots are ever captured unless you turn them on. Note: memory figures are estimates based on typical tab usage and may vary by site. 🔄 WHAT'S NEW IN 2.0.1 • Fixed: hibernated tabs now reliably wake after a browser restart. • Fixed: tabs with unsaved form text are better protected from being suspended. • Improved: whitelist now matches domains precisely (exact + sub-domains). • Privacy: tab previews are now opt-in and off by default. • Refined: redesigned dashboard and a cleaner popup.
