Tab Memory Manager

See estimated memory per tab, hibernate or close idle tabs in one click, and group tabs by domain. Everything stays on your device.

Chrome eating your RAM? Tab Memory Manager shows you exactly which tabs are the culprits — then frees the memory in one click. No accounts, no servers, no tracking. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 See memory per tab A clear estimate of how much memory every open tab is using, with a live total right on the toolbar icon. Sort by memory, idle time, domain, or "most suggested." 💤 Hibernate or close idle tabs Free up RAM without losing your place. Hibernating keeps the tab in your strip and reloads it when you click — far safer than closing. See exactly how much you'll save before you act. ✨ Smart cleanup suggestions The extension surfaces your biggest, stalest tabs — the ones safe to clear — and frees them in one tap. It never touches the tab you're using, pinned tabs, tabs playing audio, or domains you've whitelisted. 🗂️ Group tabs by domain Turn a chaotic window into tidy, color-coded groups by website, instantly. One click to group, one to undo. ↩️ Undo safety net Closed something by mistake? Every cleanup is saved to a "Recently cleaned" list so you can restore tabs with one click. 🌙 Built for everyone Fast, lightweight, no frameworks. Automatic dark mode. A clean, minimal interface that opens in under 100 ms. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Your tabs are your business. Tab Memory Manager runs entirely on your device: • No account or sign-in • No servers, no analytics, no tracking • Your tab data and stats never leave your browser ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW THE MEMORY NUMBERS WORK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Stable Chrome doesn't expose exact per-tab memory to extensions, so Tab Memory Manager shows calibrated estimates (clearly labeled "est."). If you run Chrome Dev or Canary, you can switch on real per-tab memory from Chrome's process API in Settings. Either way, everything stays local. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERFECT IF YOU ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • Keep dozens (or hundreds) of tabs open • Notice Chrome slowing down or your fan spinning up • Work on a laptop with limited RAM • Want a tab suspender that's honest, private, and simple Install it free, pin it to your toolbar, and reclaim your memory.
