Tabmanager.io vs TabTabTab

Tabmanager.io is a browser extension for organizing open tabs and windows. Users can search and filter by title or URL, sort tabs, group them by domain, suspend them, find tabs playing sound and remove duplicates. Window controls let users rename windows, move tabs between windows by drag and drop, open tabs in new windows and merge windows. Saved windows can be restored, and smart restore opens tabs suspended. Session History offers a timeline for restoring individual windows or tabs and can save snapshots automatically in case the browser crashes. Users can also create URLs to share windows. The extension runs on Chromium-based browsers, including Google Chrome, Microsoft Edge, Vivaldi and Opera. Its Free plan costs nothing and includes window and session management, saved sessions and windows, session history and basic support. Advanced costs $35.88 a year and includes Backup & Sync and priority support. Session history is saved on the local machine, not in the cloud.

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.
