Session Buddy vs Tabmanager.io

Session Buddy is a free Chrome extension for saving and restoring browser tabs, managing bookmarks, and organizing browsing. Users can save complete sessions or selected tabs, then restore them to their original windows, one window, or the current window. Its history view can restore tabs from an earlier point. Collections organize bookmarks, while unified search covers open tabs, collections, and tab history. Tabs and collections can be imported or exported in more than 15 formats, including JSON, CSV, Markdown, and HTML. Version 4.1 added automatic local backups, alongside manual backup and restore. Collections, history, and settings remain on the device rather than external services. The extension requests browsing-history permission but says it cannot read webpage content or form entries. The Free plan costs nothing and requires no account. Cross-device sync is not available.

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.
