The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
About StorageDump
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.
