New Chrome extension shows RAM
Original: I built a Chrome extension that shows which tab is eating your RAM (and frees it in one click)
Short summary
A developer built Tab Memory Manager, a privacy-first Chrome extension that displays per-tab RAM usage and hibernates memory-heavy tabs without closing them, keeping them instantly reloadable. Using calibrated memory estimates (since Chrome's stable API lacks true per-tab data), it intelligently suggests stalest and largest tabs for cleanup with batch operations and undo. Free on the Chrome Web Store with dark mode, tab grouping, and zero data collection.
- •Shows per-tab RAM usage and hibernates heavy tabs instead of closing them
