Suspend tabs without trusting a stranger
The Great Suspender died in 2021, sold to an unknown buyer and removed as malware. UtilEngine puts tabs to sleep with Chrome's own discard mechanism, on a board that also saves and snapshots your windows, from a developer whose business is selling licenses, not data.

One suspended tabs on a timer. The other makes suspension something you control, with backup underneath.

Based on public reporting of The Great Suspender's removal in February 2021 and its Web Store history. If all you want is free automatic suspension, Chrome's built-in Memory Saver or the open-source Auto Tab Discard may be all you need.
What its story should teach us
The Great Suspender didn't fail as software. It failed as a custody arrangement. Millions of people handed every postponed tab to a free extension, the extension changed hands quietly, and the new owner shipped tracking code. When Google pulled the plug, tabs that were suspended at that moment pointed at the extension's own placeholder pages, which no longer existed. People lost work twice: once to the malware scare, once to the removal.
The technical lesson is about the placeholder pages. UtilEngine's sleep uses the discard mechanism built into Chrome itself, the same one Memory Saver uses. A sleeping tab keeps its real URL in the tab strip and needs nothing from us to wake up. Remove the extension tomorrow and every sleeping tab is still just a tab.
The custody lesson is about incentives and backup. UtilEngine is a one-time purchase, so there is no reason for your data to be the product, and your tabs never ride on the extension anyway: windows can be saved as sessions, snapshots run every hour, and saved sessions sync with your account. Suspension in 2026 shouldn't be an act of faith in an extension. It should be a convenience sitting on top of a backup.
How it works in UtilEngine
Sleep for the tabs you keep, sessions and snapshots for the windows you close.

What happened to The Great Suspender?
The original developer sold it in 2020 to an unknown buyer, who shipped updates with tracking and remote code execution. Google removed it from the Chrome Web Store in February 2021 and remotely disabled it, which left tabs it had suspended stranded on broken placeholder pages.
Is The Great Suspender safe to install now?
The original is gone and should stay gone. The Marvellous Suspender is a community fork of the last clean version, open source and volunteer maintained, if you want the closest thing to the original.
Does UtilEngine suspend tabs automatically?
No, and that's deliberate. Chrome's built-in Memory Saver already suspends idle tabs automatically. UtilEngine adds what Chrome doesn't have: sleep on demand for a tab or a whole window, and one board that shows everything that's asleep, including tabs Memory Saver discarded.
What happens to sleeping tabs if I remove UtilEngine?
Nothing. Sleep uses Chrome's own discard mechanism, so a sleeping tab is a normal tab with its real address. There is no placeholder page and nothing that depends on the extension. That failure mode is exactly how The Great Suspender burned people.
Do sleeping tabs lose anything?
The page reloads when it wakes, so unsaved form input is gone. The tab, its address, and its place in the window all stay. For anything you'd hate to lose, save the window as a session first.
Are there free alternatives?
Yes. Chrome's Memory Saver is built in and covers automatic suspension. Auto Tab Discard is open source and adds a configurable idle timer. UtilEngine is for people who also want manual control, session backup, and the rest of the launcher.
