TabRest

Cut Chrome CPU and memory by auto-suspending idle tabs. Whitelist the ones you keep.

Too many tabs slowing your browser down? TabRest quietly puts idle tabs to sleep so Chrome uses less CPU, less memory, and less battery — without closing a single tab. A suspended tab stops running its scripts, ads, timers, and background activity. Its memory drops to nearly zero. The tab stays right where it is in your tab strip, and the moment you click it, it reloads exactly where you left off. ★ WHY TABREST • Free up RAM — 20 idle tabs can give back 1–2 GB • Lower CPU & heat — background tabs stop burning cycles, your fan quiets down • Longer battery — less CPU means more time unplugged • Keep every tab — nothing is closed, just parked • Great for tab hoarders and low-memory laptops ★ FEATURES • Auto-suspend idle tabs after a time you choose (5m / 15m / 30m / 1h or custom) • One-click "Never suspend this site" — no manual typing • Right-click any page to suspend it or whitelist the site • Per-site idle rules — suspend news fast, keep docs alive longer • Form guard — never suspends a tab where you're typing • Undo last suspend and restore-all buttons • Keyboard shortcuts: Alt+Shift+S (this tab), Alt+Shift+A (all tabs) • Live stats — tabs suspended and estimated RAM saved • Toolbar badge shows how many tabs are resting • Clean popup with light and dark mode ★ NEVER SUSPENDED The active tab, tabs playing audio, pinned tabs, tabs with unsaved form input, whitelisted sites, and browser pages are always left alone. ★ PRIVACY TabRest runs entirely on your device. It sends no data anywhere. Settings sync through your own Chrome account. The form-guard only checks whether a field has unsaved input — it never reads or transmits what you type. Install TabRest, pick your idle time once, and let your idle tabs rest.
