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.
