About Tab Memory Monitor & Smart Sleep

| Monitor system memory pressure and safely sleep inactive Chrome tabs. Keep large tab sessions under control without losing the pages you still need. Tab Memory Monitor & Smart Sleep shows your computer's current memory pressure, ranks inactive tabs by cleanup priority, and lets you unload tabs while keeping them visible in Chrome. Sleeping tabs reload when selected again. | Features - View available and used system memory. - See whether memory pressure is healthy, moderate, high, or critical. - Rank tabs by cleanup priority using inactivity and safety signals. - Sleep individual tabs without closing them. - Run Smart Cleanup manually. - Optionally run Smart Cleanup when available system memory becomes low. - Protect pinned tabs, audio-playing tabs, Gmail, Google Docs, and any other websites you choose. - Review a 60-minute system memory graph. - Review cleanup history and observed changes in available memory. - Keep all extension data local to your device. Stable Chrome does not provide extensions with exact memory usage for each tab. The extension therefore shows real system-wide memory and separately ranks tabs by inactivity-based cleanup priority. It does not present cleanup priority as per-tab memory. | Privacy No ads. No analytics. No account required. No browsing data is sent to the developer or to third parties in this version.
