Tabstash

Save browser tab sessions locally.

Tabstash saves browser work sessions locally so you can return to them later. Save the current window or all ordinary windows, preview included and excluded tabs, and restore sessions to new windows while preserving the saved window structure or merging it into one window. You can search, rename, inspect, and delete saved sessions. Tabstash also supports local JSON backup and import. The free version stores up to five sessions. It supports English and Simplified Chinese. Tabstash does not require an account, upload session data, use cloud sync, or collect analytics. It stores session data locally in the browser.
