Browser Storage Inspector — localStorage, sessionStorage & IndexedDB
Inspect everything a site stores in your browser: localStorage andsessionStorage items with their values and byte sizes,IndexedDB databases and object stores, and the totalstorage estimate versus your quota. Filter entries, export as JSON, and clear individual storage areas — all 100% locally.
Great for debugging why a site forgets your preferences, auditing how much space a web app uses, and understanding your browser's storage pressure.
