The 5 Best Tab Management Extensions to Save Chrome RAM in 2026

Chrome can use a lot of memory when you keep dozens of tabs open, and on a laptop that's when the fans spin up and switching tabs slows down. Chrome's own Memory Saver (Settings, then Performance) already puts some inactive tabs to sleep. A tab manager adds more control: choosing when tabs sleep, finding a tab quickly, and saving sets of tabs to reopen later.

Here are five worth knowing in 2026 and what each one is best at. Disclosure: the first is made by Patrick Bushe, who runs this site.

#1. Tab Manager by Patrick Bushe

A small, free extension that focuses on the three things most people need from a tab manager.

What it does:

• Puts idle tabs to sleep: tabs you haven't looked at for a time you choose (15 minutes to 4 hours) are unloaded with Chrome's own tab discarding, which frees the memory they held. They reload when you click them. Pinned tabs, tabs playing audio and sites on your never-sleep list stay awake, and Alt+Shift+S puts every other tab to sleep at once.
• Saved sessions: save a window's tabs under a name and restore them later in a new window, with the tabs asleep until you open them.
• Search: find any open tab across all your windows from the toolbar.
• Private: no account, and your tabs and sessions stay on your computer. The only thing it loads from the internet is its fonts, from Google Fonts.

It doesn't sync between computers or share tabs with a team. Its Chrome Web Store listing is on the way, and this page will link to it once it's live.

#2. Workona

Workona organizes tabs into workspaces, one per project, and syncs them across computers. It's built for people juggling many projects and for teams that share links and documents.

• The trade-off: it needs an account, and its bigger features are in paid plans. If all you want is to save memory, it's more than you need.

#3. Toby

Toby turns your New Tab page into a board of tab collections that you can drag tabs into and open as a group.

• The trade-off: it's an organizer rather than a memory saver. It doesn't put background tabs to sleep, so pair it with Chrome's Memory Saver or a tab suspender.

#4. The Marvellous Suspender

An open-source fork of The Great Suspender, which was removed from the Chrome Web Store in 2021 after it was found to contain malware. It suspends tabs after a set time, has detailed settings, now runs on Manifest V3 and is actively maintained.

• The trade-off: it's built for suspending tabs, not organizing them, so for workspaces or a visual board you'd pair it with another tool.

#5. Session Buddy

Session Buddy has been around for over a decade and is a dependable way to save and restore sets of tabs, especially after a crash. Version 4 rebuilt it for Manifest V3.

• The trade-off: it saves and restores tabs but doesn't put idle tabs to sleep, so pair it with Chrome's Memory Saver or a tab suspender to save memory.

The verdict: For saving memory with no setup, start with Chrome's Memory Saver, and add Tab Manager by Patrick Bushe if you want to choose when tabs sleep, search them and save sessions. Pick Workona for team workspaces, Toby for a visual board, The Marvellous Suspender for fine-grained suspend settings, and Session Buddy for crash recovery.
