What is Local Storage Viewer?
A localStorage viewer lists keys and values stored by websites in your browser’s localStorage. Developers use it while debugging client-side state, auth tokens (when not in HttpOnly cookies), feature flags, and cached UI preferences.

Examples
Typical keys
Storage is origin-scoped — you only see data for the site you’re on.
Input
theme=dark, sidebar=collapsed
Output
Listed as editable key/value rows for the current origin
Common Mistakes
- Expecting to see another site’s storage (browsers isolate origins)
- Storing secrets in localStorage (XSS can read them)
- Confusing localStorage with sessionStorage or cookies
Tips & Best Practices
- Prefer HttpOnly cookies for session tokens when possible
- Use Application → Local Storage in DevTools for deeper inspection
- Pair with Cookie Parser when debugging auth across storage types
Frequently Asked Questions
Is localStorage the same as cookies?
No. localStorage is a JS-accessible key/value store; cookies are sent with HTTP requests.
They solve different persistence problems.
Can websites see each other’s localStorage?
No. Storage is partitioned by origin (scheme + host + port).
Only scripts on the same origin can read those keys.
