StorageDump

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

StorageDump gives you a complete view of everything a website stores in your browser — cookies, localStorage, sessionStorage, IndexedDB, Cache API, and Service Workers — all in one place. Key Features One-click scan — open the popup and instantly see every storage category detected for the active tab. Smart badge — the extension icon shows a live count of detected storage categories so you always know what a site is using. Full export — download all storage data as a structured ZIP or combined JSON with a single click. Dashboard view — drill into each category with a full-page inspector that shows raw keys and values. Cookie support — reads both standard and partitioned (CHIPS) cookies using Chrome's native cookies API. Auto-refresh — switches context automatically when you change tabs. Use Cases Debugging web apps and checking what data a site persists. Security and privacy audits — see exactly what cookies and storage a site sets. Data export for testing or migration. Verifying that GDPR or cookie-consent flows actually clear storage. Supported Storage Types - Cookies (including partitioned / CHIPS) - localStorage - sessionStorage - IndexedDB - Cache API (Service Worker caches) - Service Workers StorageDump reads and exports your browser's storage data for the active tab. It does not send any data to external servers.
