TabCost helps you find the tabs that slow Chrome down — fast. See which tabs are using the most memory, which ones are “busy”, and hibernate idle tabs to keep your browser smooth. Why you’ll love it Instant visibility: See per-tab memory (JS heap) + an activity estimate Find offenders quickly: Filter All / Heavy / Idle 10m+ Search tabs: Find any tab by title or URL One-click cleanup: Hibernate (discard) idle tabs to free resources Keyboard friendly: ↑ / ↓ to navigate Enter to hibernate selected Esc to clear Ctrl/Cmd + K to search How it works TabCost measures performance signals locally in your browser. Some restricted pages (like chrome:// or system pages) don’t allow measurement—those tabs may show unavailable metrics. Privacy first No tracking No analytics No data collection No servers — everything runs on-device
