Description from store Cluster is a window and tab manager extension for Chrome that helps you manage multiple open tabs and windows while using minimal system resources. Cluster also comes with the tools for quick navigation to open windows and tabs, and a tab project manager to easily save and restore windows and tabs sessions as working projects. Restored windows launches each tab in a suspended state to minimize the load time when opening lots of tabs at once. Features include undo removed tab or window, sorting windows tabs for better overview, showing the real tab URL when using the Great Suspender, launch the manager using keyboard shortcut, option to save or restore sessions from the manager or drop-down menu, search and filter for tabs by title or URL, easily move tabs between windows, suspend all windows tabs, and more.

  • (2023-03-19) Vinícius: Best window e tab manager ever created, you can organize and browse through all windows/tabs from just one main window, no need to alt + tab and searching for your window
  • (2023-03-17) Mitchell Lokey: The extension is pretty great, but I ran into one MAJOR issue. Hotkey assignments need to optional! Cmd+M is a hotkey in the extension but also Macs hotkey for minimizing a window. Cmd+, is this extensions quick sort hotkey, it's also the hotkey for subscripts in google docs, AND for mac preferences. Will delete this extension if not resolved :( Google docs is more important and resorting my tabs after quick sort messes them up is not worth the hassle. It's great otherwise, keep it up!
  • (2023-03-17) Zion Butbika: אחלה כלי לניהול חלונות של כרום
  • (2023-03-07) Carissia Dudley: its's awesome! Love it and use it everyday, it saves me so much trouble
  • (2023-02-24) Kartik Gowda: No options to replace tabs with current ones for updated web pages.
  • (2023-02-01) April Papajohn: Just the remove-duplicates and sort functions alone make this extension really helpful.
  • (2023-01-26) Bryan Kinney: Duplication of windows is a problem. It can't remember if the window being saved is already a saved one. So you end up with multiple copies of the same saved window even if you use the same exact name.
  • (2023-01-25) Michael Alo: Love it. Makes browsing so much nicer. One little suggestion: to move the "Pause tabs" button away from the "Close tabs" one. I accidentally closed al my tabs instead of pausing them because of an imprecise click.
  • (2023-01-16) Nidhin Vinod: I would like to buy it but upon trying to get the license it is showing under construction.? May i know when can i buy it.
  • (2023-01-13) Welleeseempty: Не работает открытие окон двойным нажатием на окна и невозможно при выборе ссылки нажать кнопку "Save to". Отключал расширение, переустанавливал, ничего не помогло. Проблема актуальна на 13.01.2023. Прошу разработчиков исправить проблемы.
  • (2023-01-10) Adid José Acevedo Valerio: I would like if it had more sorting options, Like sort per page title, It's currently not very effective on sorting tabs from the same website.
  • (2023-01-10) Camel of Siberia: cant take back windows you delete sucks so much
  • (2022-12-28) Michael Jennings: Wow, so far this is really good. I've used a bajillion tab manager extensions, and on a whim enabled this one I installed a long time ago but disabled it (i probably grabbed 3 or 4 extensions to try later) but never enabled/tried it. It's good!
  • (2022-12-21) Brad Page: Cluster Tab Manager is everything you could want for Chrome tab management. It's easy to use and you can save windows for later. I typically find myself starting a new chrome window and researching things, like recipes and instead of bookmarking each one I find, I just save the window, tabs and all, in Cluster Tab so I can come back to it later.
  • (2022-12-14) Mike Migale: Best Tab manager, saves my life everytime to find back my tabs
  • (2022-12-12) Sam Farhadi: This is a tab that I've been always looking for saving and sorting tabs out. easy to use and simple. great job!
  • (2022-12-11) Najel L. Mills: Is this safe ? it have been years this plugin didn't recive an update
  • (2022-12-08) Zayn Shoukat: HASN'T BEEN UPDATED IN YEARS !!! WHAT IS GOING ON
  • (2022-12-02) Daniel Einspanjer: This was the first one I tried when looking to get a better tab management experience over what you get out of the native controls offered by Chrome now ( Cmd+Shift+A ). Over all, I'm very pleased. The only thing that I feel is missing is that it doesn't pick up or use the window names that Chrome has built in. If you click on the Window menu in Chrome, there is an option for "Name Window". If you do so, it will appear by that name in the window list in Chrome, but the name doesn't show up in Cluster.
  • (2022-11-29) valdano obieyisi: its perfect
  • (2022-11-29) krishna sunder: use full screen(ctrl + f11 / only f11) and use this to navigate between tabs....just amazing
  • (2022-11-27) Đorđe Jović: This is literally Tabmanager.io, but WORSE IN EVERY WAY. It doesn't have a "Open New Tab" option. It doesn't have a "Save session" option, that let's you save all the currently open tabs from all the currently open browser windows. It doesn't have an "Export session windows" option. It doesn't have a "import from file" option. The only thing it has over Tabmanager.io is that is has an option for expanding and collapsing all the open windows...
  • (2022-11-24) WarriorDX: A MUST HAVE EXTENSION
  • (2022-11-22) Regielene Gonzales: One of the best tab managers, if not the best tab manager. Please add the options to open a saved window in the current window, to open a tab in a new tab when clicked, and to undo when you just removed a tab or window.
  • (2022-11-16) Michael Wilhelm: The extension works flawlessly and really helps to organize, close, and save mutliple tabs.
  • (2022-11-08) ege şişmanoğlu: thank you
  • (2022-11-06) Darwin Arabe: the great extension and tabs organizer.
  • (2022-10-30) Amir Uval: That's the way to do it! wonderful chrome plugin to get tabs organized. Could be nice to work with chrome's lame "tab group" feature - it could work well together. But regardless - thank you devs!
  • (2022-10-28) Almaric Géo-IT: Très bonne extension. Usefull ! This extension is very nice and usefull 👍👍 but what a pity that the naming of the windows does not work.. For example if I want to move some tabs : "Windows 1 to 9" is not practical..
  • (2022-10-21) Leroy Jones: 5 star once cloud backup is working
  • (2022-10-19) Andy Briesemeister: Lässt Chrome leider immer wieder einfrieren. Sonst ist es eine gute Erweiterung. Schön wäre noch, wenn man Tabs gruppieren könnte.
  • (2022-10-15) Sabri Mostafa: إضافة رائعة للمتصفح، ومفيدة جداً بشكل يومي
  • (2022-10-12) James Herrick research: A wonderful extension. I use this constantly to keep track of all my open tabs and windows. I do find it indispensable and have no issues at all with it.
  • (2022-10-09) Goran Gligorin: It used to work great, tab deduplication was awesome, but it seems to have been abandoned. I was waiting for cloud sync to become available, but it seems that it was too good to be true. The only export formats are either CSV or JSON, but sadly no HTML, so you could open the document in the browser.
  • (2022-09-27) Stephanie Henry: I was so excited to find what seemed like a better onetab, and that supports cloud syncing. Of course syncing is a premium feature, and I clicked the buy button so fast... and guess what... NOPE! Can't buy it, and this hasn't been updated since 2019. It's an abandoned project. You get 1 star just for wasting my time.
  • (2022-09-27) VFrost VFrost: Cluster - Window & Tab Manager Has always been one of my favorite tab manager/organizers... works well... *** But why has it not been updated since August 4, 2019? *** why was it disabled by Chrome?
  • (2022-09-22) Mayank Gupta: Please add more features!
  • (2022-09-10) Sery christian renaud: thank
  • (2022-09-05) Jack Callcott AU: I do like this extension a lot. I tried about 4 tab managers before finally settling on this one as the best. I can only say that it suits me, and is a very useful piece of software for me. You can do things like mute any tabs or make them hibernate so you can have a lot of tabs open and save memory space in the RAM. You can also save a whole window of tabs and bring it back to life later on. I really need this kind of tab manager for the work I do. I'd be lost without it. As I said, I did try 4 or 5 tab managers and they were all OK, but this one was the best for me.
  • (2022-09-04) Barbara: I really like this tab manager. REALLY. But it looks like it has been abandoned. I did a power wash on one of my chromebooks and the information is stored locally. I hadn't realized that the info wasn't syncing. Oh well. There is an option for a paid version that syncs but its "under construction" and the last date is August 2019. I hope he and his family survived CoVid okay. Any idea how we might urge the developer to please come back and help all of us OCD types who go tab crazy to please come back and save our tabs (and our minds)? I will look at the other tab managers but the last time I looked most of them just weren't easy or straight forward enough. This one has all the basics and if it had syncing or cloud storage it would be 5 stars. cheap as I am I would pay for the premium version. Also if he isn't updating to keep up with Chrome OS changes, at some point, this will become unusable.
  • (2022-08-30) J S: Lifesaver for when I have 50 tabs poorly organized across 4 windows and want to go to bed without killing my computer overnight
  • (2022-08-29) Назар Чуваковський: Good app, but it would be wery cool if I could choose opened window tabs will be suspended or no becouse, I open windows to make bookmarks from meny tabs,and if I make bookmark it save`s link of extension, and when I open that link if extension is closed, it dont shows page, but broken link, it`s hard to reload every tab to save correctly as a bookmark if there are meny Also Chrome closes tabs wich are suspended by Cluster if it is disbled It would be cool if you add that option
  • (2022-08-28) Davi Bartav: Tem que nomear a tab a ser salva --' O Tabs Outline é MT melhor
  • (2022-08-22) Pressuposto: Perfeita.
  • (2022-08-13) Erkin Dalkilic: Muhteşem Bir Eklenti...
  • (2022-08-03) PR BM: Se crashea en Edge.. seria bueno que lo arreglaran.. y deja de funcionar y no graba los bookmarks o lotes de pestañas.
  • (2022-08-02) Wen-Chi Chang: This extension met my needs very well. following is some suggestions for better use: 1. add a trash bin function for accidentive detete or just add a delete confirm dialog.
  • (2022-07-20) ツDouglas: Perfeito
  • (2022-07-18) Legacy User: Pretty sweet. For years, it's been the best.
  • (2022-07-11) Андрей Нов: Классное дополнение, только вот один косяк пока нашел: - при закрытии окна в менеджере - оно все еще отображается, и видимо после этого связь с "отображаемого окна" с реальным окном теряется.. поправьте пожалуйста! будет очень круто)

  • (2019-08-31, v:2.2.6) Carlos Hernández: Recovering the last session
    I understand that Chrome is already recovering from the last session ......, But Chrome only gives you the option to recover the session when you start chrome ......, If you do not recover the session when you start chrome it is already difficult to recover it. without some extension ......, and that is where you have to open 350 tabs at the same time ......, In addition, Chrome sometimes fails to make the recovery, or does it halfway ........., It would be good if you could see the Sessions Recovered automatically in CLUSTER ....., It's a feature that I like about Sessión Buddy, Because I don't have to worry about opening 350 tabs when Chrome started to be able to recover the Session ......, but if this feature were in CLUSTER I would only use CLUSTER ......., I currently use the 2 extensions at the same time ........, I have 3 days that I discovered CLUSTER and I like it a lot ........., I wish this important option could be taken into consideration ....... Best regards and thank you very much in advance
  • (2019-08-30, v:2.2.6) Carlos Hernández: Recover Session
    The session is not saved when Chrome closes unexpectedly, you can only retrieve the tabs that were saved for the first time, What happens if I open 10 more tabs? those tabs how do I get them back?

  • (2019-08-08, v:2.2.6) Royal Flusher: Re-open windows full screen ?
    Hi, I always use Chrome fully maximized to take up the whole screen. Trying out Cluster tonight and when I re-open a saved window, it opens up in a window that takes up a little more than half the screen. Can Cluster open saved windows fully maximized always?
  • (2019-08-07, v:2.2.6) Jason Farr: Awesome Work! Please give us the ability to Custom Name the windows.
    Please give us the ability to Name the windows ! ;) Instead of window 1, etc. Custom name eg. Development, Customers, etc Thank YOU!
  • (2019-08-05, v:2.2.6) Ryan Rolnicki: Great utility! Can we create filters?
    So rather than breaking out tabs into new windows, I'd like to simply create 'filters' in the tab listing UI, so instead of headers like 'Window 1', 'Window 2', etc, I would have 'Filter 1', 'Filter 2', etc. Even a simple 'domain regex' as filter would suffice. The goal would be I would create a filter for JIRA, a filter for Github, a filter for Wiki...and then the default one would list everything (or everything not shown in a filter, as a toggle-able option). Alternately, if 'sort by domain' allowed me to specify I wanted the domains tiled across multiple columns the way multiple windows are (and if I could specify a title/increase title size) for the sort-by-domain groups, that would work equally well, and probably be really useful for others as well!
