OneTab vs TabTabTab

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.

TabTabTab is a free Chrome extension for organising browser tabs across windows. It presents pinned, grouped, and standalone tabs in one list and lets you rearrange them by drag and drop. Tab groups and entire window sessions can be saved and restored, while automatic grouping works by domain or subdomain. The extension can alert you to duplicate tabs, merge windows, track tab access time, copy URLs, capture screenshots, search tabs, and clean up automatically. A side-panel overview and dark mode are included. The Chrome Web Store lists the extension with 3,000 users. The project’s public GitHub repository uses the MIT license, and the developer says the extension will not collect or use user data. Support information points to a desktop-browser support page and GitHub Discussions for questions, suggestions, and bug reports. The listed Free plan costs nothing, with no paid tiers or usage limits stated.
