The update I previewed is now in the Chrome Web Store. TabVitals 0.4.20 adds Auto-suspend for Chrome on Mac and Windows.

Turn it ON to scan and sleep eligible background tabs right away. It repeats every 30 minutes, 1 hour, or 2 hours, while active, pinned, and audio-playing tabs stay protected. Mark important sites Always Awake. Tabs remain open and reload when you return.

After each cycle, TabVitals shows the change in available system memory and how many tabs were slept. The manual X-Ray scanner is still there, along with one-site cache/cookie cleanup, Incognito, and history tools. Save unfinished work before sleeping tabs.

I m testing the next TabVitals update: Auto-suspend for Chrome.

The manual X-Ray scanner and tab-sleep controls are staying. The new option automates that workflow: switch ON to scan and sleep eligible background tabs immediately, then repeat every 30 minutes, 1 hour or 2 hours.

Free up RAM without closing your tabs or remembering to run cleanup yourself. Keep active, pinned and audio-playing tabs protected, and mark important sites Always Awake. Sleeping tabs reload when you return. A clear result card shows the measured change in available memory after each cycle.

Chrome on Mac and Windows; diagnostics run locally. The existing cache/cookie tools, one-click Incognito and one-site history removal remain available.

TabVitals v0.4.16 is now available in the Chrome Web Store. We've refined X-Ray's loaded-tab scan and made its memory readings clearer, so you can spot tabs worth sleeping without closing them. Chrome does not expose complete RAM data for every tab, so a scan is a guide, not a promise of exact savings.

The current beta also puts useful actions for the current website in one place: open it in Incognito, remove only that site's visits from Chrome history, and clear cache or cookies for that site without resetting everything else. You can keep important sites awake while sleeping unneeded background tabs. Diagnostics run locally.

Try v0.4.16: https://chromewebstore.google.co...

If you test it with many tabs, I'd especially value feedback on missing tabs or memory readings that look wrong.

TabVitals v0.4.9 is now available in the Chrome Web Store.
What s new:
Open the current tab directly in Incognito
Remove only the current website from Chrome history
Updated Site Tools for faster one-site troubleshooting
You can still find heavy tabs, sleep safe background tabs without closing them, and clear cache or reset data for only the current website. Active, pinned, audio, and Always Awake tabs stay protected.

I d love to hear which of the new site-level tools is most useful in your workflow.

We re expanding the Site Tools section with two new actions:

Open the current website in Incognito

Remove only the current website from browsing history

The existing Fix this site, Full reset and Always Awake tools remain in the same place giving you one panel for troubleshooting and managing the current website without affecting everything else in Chrome.
