Persistent State Intelligence

Interactive portal for managing LocalStorage and SessionStorage. Audit persistent objects, clear cached states, and debug state synchronization.

Web Storage Architecture

Web Storage provides mechanisms by which browsers can store key/value pairs, in a much more intuitive fashion than using cookies. The two main types are LocalStorage (persists after the browser is closed) and SessionStorage (expires when the tab is closed).


Storage Limits: Modern browsers typically allocate about 5MB to 10MB of space per origin. It is important to note that data stored in LocalStorage is not encrypted and remains accessible to any script running on the same origin (XSS vulnerability risk).
