StorageDump

About

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

StorageDump reads and exports your browser's storage data for the active tab. It does not send any data to external servers.
