The Great Suspender Alternative: Safe Options in 2026 (Compared)

If you are looking for a Great Suspender alternative, you are probably one of the millions who relied on it to put idle tabs to sleep, then watched it disappear. The good news: Chrome now has a built-in version of the same idea, and several extensions do the job without the history.

This guide explains what happened, how to judge the forks, and six safe ways to sleep tabs in Chrome in 2026, with numbers we checked on the Chrome Web Store.

The short answer#

• Chrome's Memory Saver does most of what The Great Suspender did, free and built in.
• Want an exact timer? Use an extension built on Chrome's own tab discarding.
• Be careful with forks: check publisher, update date and permissions.
• Our comparison table has users, ratings and update dates as of Oct 18, 2026.

What we measured on a Mac#

Tested on a MacBook Pro (M1 Pro) with 16 GB of RAM, macOS 26.3, Chromium 153 (the open-source build Chrome is made from, used because branded Chrome no longer loads test extensions from the command line), October 21, 2026. Modern replacements for The Great Suspender use Chrome's own tab discarding instead of swapping pages for a placeholder. We measured what that is worth with ten real sites open. Memory is the total footprint of every Chrome process in a fresh test profile, read with macOS's footprint tool.

That is about 2.8 GB back. Collapsing the same nine tabs into a group, for comparison, saved nothing (4,092 MB). Whatever you pick, make sure it actually discards tabs.

What happened to The Great Suspender?#

The Great Suspender was an open-source extension that replaced idle tabs with a lightweight placeholder page. It had more than two million users. In 2020 the original developer sold the project. Security researchers and the community then raised concerns about the new owner's versions, and on February 4, 2021 Google removed it from the Chrome Web Store, flagged it as malware and turned it off in people's browsers. Microsoft had already blocked it in Edge.

Then came Manifest V3. Chrome stopped running older Manifest V2 extensions in 2025 and removed the remaining ones from the Chrome Web Store in 2026. Many old suspender clones did not make that jump.

How did The Great Suspender work, and why does it matter?#

It replaced each sleeping tab with a page inside the extension. That is why, when the extension was turned off, suspended tabs broke and showed errors.

Modern tools mostly use Chrome's own tab discarding instead. A discarded tab keeps its real address and stays in the tab strip; Chrome throws away the page from memory and reloads it when you click. If you uninstall the tool, your tabs are still normal tabs. That is a big safety improvement, and a good thing to look for.

1. Chrome's built-in Memory Saver#

Go to Settings, then Performance, and turn on Memory Saver. Pick Moderate, Balanced or Maximum. Chrome deactivates tabs you are not using; they reload when you click. Tabs playing audio or video, pinned tabs, downloads, half-filled forms and sites you list under Always keep these sites active stay awake.

What it lacks: an exact timer, duplicate cleanup, and a view of which tab is heaviest. See Chrome Memory Saver explained.

2. Auto Tab Discard#

A long-running extension that discards inactive tabs using Chrome's native mechanism, with a configurable timer and per-site rules. When we checked on Oct 18, 2026, its Chrome Web Store listing showed about 200,000 users, a 4.0 rating and an update dated October 12, 2026.

3. The Marvellous Suspender#

A fork of the original open-source Great Suspender code, made to be a clean continuation. Listing on Oct 18, 2026: about 100,000 users, a 3.3 rating, last updated September 17, 2026. Because it descends from the original design, check how it suspends tabs and what happens to them if you remove it.

4. Tab Wrangler#

Not a suspender: it closes tabs you have not used for a set time and keeps them in a list you can reopen. It skips pinned tabs and tabs playing sound. About 60,000 users, a 4.2 rating, updated October 15, 2026.

5. OneTab#

Also not a suspender: one click collapses all your tabs into a list on a single page and closes them. About 2,000,000 users and a 3.8 rating on Oct 18, 2026. Good for parking a pile of tabs; less good if you want them to stay in your tab strip.

6. Cleaner (our extension)#

We make Cleaner, so weigh this accordingly. Cleaner Pro uses Chrome's native discarding to put tabs to sleep after 30 minutes without use, never touching the tab you are on, pinned tabs or protected sites, and closes duplicate tabs in one click. The free version clears cache and cookies for one site at a time and includes a Tab Manager side panel that sorts tabs by estimated memory. It is small: about 116 users on Oct 18, 2026. Pro is a one-time $19.99 for up to three browsers, with no subscription and no account.

Are The Great Suspender forks safe?#

Some are maintained by careful people; some are copycats using the famous name for installs. Before you install any suspender:

1. Publisher. Who offers it? Is there a website and a contact?
2. Last updated. A tab tool untouched for years may break with Chrome's next change.
3. Permissions. A suspender needs tab access. Be wary of extras it does not need.
4. How it sleeps tabs. Native discarding leaves normal tabs behind if you uninstall it. Placeholder pages break.
5. Recent reviews. Sort by newest, not by most helpful.

Which one should you pick?#

• Just want less memory use: Chrome's Memory Saver on Balanced or Maximum.
• Want an exact timer, free: Auto Tab Discard.
• Prefer closing over sleeping: Tab Wrangler or OneTab.
• Want sleep plus duplicate cleanup and per-site cache cleaning in one tool: Cleaner Pro.

The bottom line#

The Great Suspender is gone for good, and you do not need a risky clone to replace it. Turn on Chrome's Memory Saver first. If you want a fixed timer or extra tools, pick an extension that uses Chrome's native discarding, is actively updated and asks only for the permissions it needs.
