UnDupe: Clean up your Chrome tabs Too many tabs open? UnDupe helps you clean up duplicate tabs, save windows for later, and quickly reopen groups of tabs you use regularly. Everything stays on your computer. No accounts, no tracking, no ads, and no external servers. Clean up duplicate tabs UnDupe finds duplicate tabs across all your open Chrome windows and lets you clean them up in one click. It keeps the tab you accessed most recently and closes the extras. You can also clean duplicates for a specific website or URL. Save windows for later Have a window full of tabs that you don't need right now? Save it to your Library and close it. Your tabs are still there when you need them. Search and filter your saved tabs, restore them individually or bring back an entire window at once. Accidentally deleted something? You can undo it. Save tab groups for things you do often Create groups for your regular workflows — research, work, travel planning, or anything else that requires the same set of tabs. Open a saved group in one click whenever you need it. UnDupe can also use your local browsing history to show useful URL insights and identify websites you visit frequently. Import & export Move your saved tabs and groups between devices using a simple JSON file. You can also paste multiple URLs at once to quickly build a collection.
