Browser Storage Inspector
/browser-storage-inspectorView and inspect localStorage, sessionStorage, and cookies stored by websites in your browser.
Websites quietly store data in localStorage, sessionStorage, and cookies — and you rarely get to see what they left behind. This inspector lists everything a site has stored on your device, including sizes and expiry details. It is a practical privacy tool for auditing what a website tracks. Your data is read locally and never transmitted anywhere.

FAQ
Frequently asked questions
Everything you need to know about browser storage inspector.
What storage types are inspected?
localStorage, sessionStorage, and cookies belonging to the current site, shown together or filtered by type tabs with per-tab counts.
Is this tool safe to use?
Yes. It only reads data already stored in your browser for this site. Nothing is written, deleted, or transmitted anywhere.
Why is the list empty?
Websites can only access their own origin's storage. If the current site has never stored anything, all three tabs are empty by design.
Can I delete entries with this tool?
No. The inspector is read-only by design. Use your browser's developer tools, such as the Application panel in Chrome, to remove entries.
Why are long values cut off?
Values longer than 200 characters are truncated in the preview for readability. The copy button on each entry still copies the full value.
Does it show other websites' cookies?
No. Browser security scopes storage and cookies to the current origin, so third-party data is never visible here.
