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.
