StorageDump

Inspect and export cookies, localStorage, sessionStorage, IndexedDB and Cache API for any site you visit.

StorageDump shows you, in one place, what the site in your current tab has saved in your browser: its cookies, local and session storage, IndexedDB databases, cached files and service workers. You can look through it, change or remove entries, and save a complete copy to a file. How it works Open the site, click the StorageDump icon and press Scan. You get a summary of what the site uses. Press Export all to save a ZIP or JSON file to your Downloads folder, or open the dashboard to browse each part in detail. What you can do - Review a site's data in a full-page dashboard, down to individual database records. - Edit or delete entries to test how a site behaves with different data. - Save an exact copy: values are written as stored, and large exports are split automatically. - Include cookies that page scripts cannot see, such as HttpOnly cookies. - Hide values that look like passwords or tokens before you share an export. - Keep a short history of your exports with a checksum for each file. Who it is for Web developers debugging their own apps, QA engineers capturing test state, and anyone checking what a site keeps after logging out or clearing consent. Privacy StorageDump reads a site only when you press Scan or Export; nothing is read in the background. There is no server, no account and no analytics. Exported files go only to your Downloads folder. The source code is open (MIT) on GitHub.
