OneTab vs tabExtend

OneTab turns open browser tabs into a saved list that users can restore one at a time or all at once. It works with Chrome, Firefox, Edge, Safari, and other browsers, and is listed for macOS and Windows. The maker says reducing open tabs can save up to 95% of memory. Saved tabs can be organized into folders, reordered, merged, or managed with quick lists, search, tasks, and stars. Users can import and export tab lists or share a list as a web page. OneTab is free, with no signup required for tab saving and organization. Its optional Backup & Sync encrypts data on the device before upload and uses end-to-end AES-256 encryption, according to the maker. Sync covers saved tabs and settings, not browsing history or currently open tabs. OneTab remains accessible offline, and changes made offline sync when the user is online again. A single Backup & Sync license covers multiple computers, browsers, and profiles, up to 100.

tabExtend is a visual tab manager that adds notes, images, and reminders inside the browser. Users can save, close, and reopen groups of tabs with drag-and-drop or right-click actions. It also supports to-dos, colored notes, and reminders for sites and items. Workspaces and categories can be shared privately or publicly, with colleagues invited to collaborate in real time. Workspaces sync to the cloud for use across devices; tabExtend says its stored data is end-to-end encrypted and backed up twice a day. Search helps locate saved items, and groups can be generated from bookmarks and most-visited sites. The extension is available for Chrome, Brave, and Edge, with native apps for Android and iPhone/iPad. The free plan includes basic features and up to 30 saves, with unlimited time and no account required. Pro is $8 a month; Team is $21 a month for three seats, with additional seats at $7 each. The extension can replace the new-tab page and read browsing history; downloads, most-visited URLs, and bookmarks are optional permissions.
