Tabcrate - Tab & Session Manager

About

Forty tabs open and no way back if something goes wrong. Tabcrate gives you a session manager you can actually trust.

Stash the tabs in any window into a named session, bring them all back with one click, and know your data is safe: every change is backed up automatically on your own device, and a full export is always one click away.

Here's what you get:
- Save a session instantly. One click, a right-click, or a keyboard shortcut stashes every tab in the window into a named session you can find again later.
- Restore exactly how you want. Reopen a session in the current window or a brand new one, or click a single tab to open just that one. Pinned tabs stay pinned.
- Nothing is ever silently lost. Deleting a session or removing a tab is always undoable with one click, and restoring a session never deletes it.
- Automatic safety snapshots. Tabcrate keeps the last dozen states of your whole vault on-device, so you can roll back if anything ever goes sideways.
- Back it up for real. Export your entire vault to a JSON file whenever you want, and import it back with a merge or a clean replace.
- Lock what matters. Lock a session so it can't be deleted by accident.
Private by design. Everything lives on your device in local storage. No account, no cloud, no tracking, no ads, and nothing ever leaves your machine.

Every feature is free, with nothing behind a paywall.

Stop losing tabs to a crash or a bad click. Save them once, and get them back exactly as you left them.
