TabSill — save & restore tabs, offline

Save windows as sessions, restore them with groups intact, auto-snapshots so nothing is lost. No account. Data stays on your PC.

TabSill saves any Chrome window as a named session and brings it back exactly as it was: same order, same tab groups and colours, pinned tabs still pinned. - Save this window or all windows in one click (Alt+Shift+S) - Restore a session in a new window, add it to the current one, or tick only the tabs you need - Automatic snapshots every 5 minutes while something changes — a crash, an update or a wrong click never costs you your research - 30-day trash for deleted sessions - Bring your existing collections: import the export file of another tab manager, a bookmarks file or a plain list of URLs - Export everything to a JSON file for backups or to move to another computer Private by design: no account, no cloud, no tracking. Your sessions are stored only in this browser. TabSill makes no network calls, except the licence check if you activate Pro. Free, with no limits on sessions or tabs. TabSill Pro (€19 once, forever) adds 30 days of snapshot history, search across all sessions and snapshots, a duplicate cleaner, suspend inactive tabs, custom shortcuts, tags and colours. TabSill was called "Tab Shelf" until September 2026: only the name changed, your data and licence keep working.
