Tab Safety Net

Automatic local backups of your browser windows, tabs and tab groups. Restore them after a crash, an update or a mistaken "Close all" — in one click.

• Snapshots every few minutes and right after your tabs change.
• Keeps tab groups, pinned tabs and window layout.
• "Previous session" button after a restart.
• Optional tab sleeping that never loses a tab's address.
• Export and import backup files.

Private by design: everything stays on your computer. No website access, no network requests, no account, no tracking.

Works in Chrome, Edge and Brave (version 121 or newer).
