TabNexa

Keep your browser fast, clean, and organized by managing open, duplicate, and stale tabs.

TabNexa – Privacy-First Tab Manager TabNexa helps you organize browser tabs, find duplicates, and keep your workspace clutter-free — entirely on your own device. As you open more tabs across work, research, and browsing, it gets harder to find what you need and easier for your browser to slow down. TabNexa scans your open tabs, identifies duplicates, groups related tabs by domain or workspace, and gives you a clear health score for your browser — all without sending any data off your device. Key features: Tab Manager – view, search, and act on all open tabs in one place Duplicate Detection – find and close duplicate tabs in one click Workspace Management – group tabs by project, topic, or task Domain Grouping – automatically cluster tabs from the same site Browser Health Score – a quick, locally-calculated view of your tab organization Sleeping Tabs – suspend inactive tabs to save memory, restore instantly when needed Pin Important Tabs – protect key tabs from accidental closing Bulk Tab Actions – search, switch, and clean up tabs faster Privacy by design: TabNexa doesn't require an account, doesn't use cloud storage, and doesn't run analytics or ads. All tab data is stored locally using chrome.storage.local and processed on your device — nothing is transmitted externally. How it works: TabNexa uses chrome.tabs to read tab titles and URLs for duplicate detection and grouping, chrome.storage.local to save your preferences on-device, chrome.alarms for lightweight scheduled checks instead of constant polling, and chrome.windows and chrome.action to manage the interface. Each permission is used only for its stated purpose. Works on Chrome, Edge, Brave, Opera, Arc, and other Chromium-based, Manifest V3 browsers. Note: TabNexa doesn't replace bookmarks and doesn't optimize website performance directly — it manages how your browser handles the tabs you already have open.
