Save a window in one click to free memory, and get everything back later — even after a crash, a restart, or a window you closed by mistake. Everything stays on your computer.
The extension: no account, no analytics, no network requests. Not for sale.
Your open windows are saved every 15 minutes, only when something changed. Older snapshots are thinned out, Time-Machine style.
Every window you close is remembered with all its tabs, so a mis-click never costs you a research session.
After a crash or a restart, the last known state of all your windows is kept as a snapshot.
Deleted collections stay recoverable for 30 days.
Export to JSON, to a bookmarks file any browser can import, or to a plain list of links. Your data is never locked in.
Save this window or all windows with one click or Alt+Shift+S. Restore everything, one window or a single tab. Search across all of it.

Yes. Saving, restoring, auto-save, closed-window recovery, search, import and export are free, with no limit on saved tabs. An optional Pro upgrade with automatic backup files and longer history may come later; nothing free today will move behind it.
The browser deletes the extension's data. Export a full backup first (Import & export → Full backup) and you can bring everything back later.
