StorageLens

Inspect, export & clear site storage - localStorage, sessionStorage, cookies, IndexedDB, cache & more.

StorageLens is a powerful developer and privacy tool that gives you full visibility and control over everything a website stores in your browser. ────────────────────────────────────── 🔍 WHAT IS STORAGELENS? ────────────────────────────────────── Every website you visit stores data in your browser — cookies, localStorage, session data, IndexedDB databases, cached files and more. Most of this is invisible to you. StorageLens makes it all visible, readable, and manageable in one click. Whether you're a web developer debugging a site, a QA engineer testing storage behaviour, or a privacy-conscious user who wants to know what sites are storing about you — StorageLens gives you the tools you need. ────────────────────────────────────── ✨ FEATURES ────────────────────────────────────── 📊 STORAGE INSPECTOR - Displays all storage for the active tab in a clean, expandable tree - Shows data from all origins on the page — including third-party iframes (ad networks, analytics, CDNs) - Grouped by type: Local Storage, Session Storage, Cookies, IndexedDB, Cache Storage - Each origin is expandable with a full Key / Value table - Values are automatically decoded — URL-encoded, double-encoded, Base64, and JSON are all pretty-printed so you can actually read them - Toggle between decoded and raw values at any time 🔎 GLOBAL SEARCH - Search across all storage types simultaneously - Matches highlighted in results as you type - Shows live match count per section and per origin - Sections with no results are automatically hidden - Instantly clear the search to return to full view ➕ ADD STORAGE ENTRIES - Add new localStorage, sessionStorage, and cookie entries directly from the extension — no DevTools required - Cookie editor includes path and expiry options - Full input validation before writing to the page - Storage tree refreshes automatically after adding 🎯 SELECTIVE CLEAR - Choose exactly what to clear before wiping anything - Two groups with parent/child checkboxes: - Cache: Browser Cache, Cache Storage - Storage: Local Storage, Session Storage, IndexedDB, Cookies, Service Workers, File Systems - Your selections are remembered between sessions 📤 EXPORT TO CSV - Export any combination of storage types to a .csv file - Includes Type, Origin, Key, and Value columns - File is named automatically with the hostname and date - Useful for debugging, auditing, or sharing storage state 🌗 DARK & LIGHT MODE - Full dark mode (default) and light mode - Toggle instantly with one click - Theme preference is saved automatically ────────────────────────────────────── 👩‍💻 WHO IS IT FOR? ────────────────────────────────────── - Web Developers — debug localStorage, sessionStorage and cookies without opening DevTools - QA Engineers — inspect and manipulate storage state during test sessions - Privacy-conscious users — see exactly what sites are storing in your browser - Security researchers — audit third-party tracking cookies and storage ────────────────────────────────────── 🔒 PRIVACY & SECURITY ────────────────────────────────────── - StorageLens does NOT collect, transmit, or share any data - All operations run entirely on your local device - No analytics, no tracking, no third-party services - Storage writes use Chrome's secure scripting API — no eval(), no dynamic code execution - HttpOnly cookies cannot be created (enforced by the browser) - Open about our permission usage — see our Privacy Policy for full details ────────────────────────────────────── 🛡️ PERMISSIONS USED ────────────────────────────────────── - browsingData — to clear cache, cookies, IndexedDB and localStorage - tabs — to identify the active tab's URL - scripting — to read and write storage on the current page - host permissions — required to operate on any website you visit ────────────────────────────────────── 📦 BUILT WITH ────────────────────────────────────── React • TypeScript • Vite • Manifest V3 ────────────────────────────────────── ☕ SUPPORT THE PROJECT ────────────────────────────────────── StorageLens is completely free.
