StorageNinja

Copy, paste and manage Local Storage, Session Storage, Cookies, IndexedDB and Cache Storage of the active tab.

StorageNinja copies, pastes and manages the storage of the page you are on: Local Storage, Session Storage, Cookies, IndexedDB and Cache Storage. Built for developers and testers who switch between environments and test users every day. ONE-CLICK ACCESS TOKEN • Finds the access token (JWT) in Local Storage, Session Storage or cookies and shows it at the top of the popup. • Shows the subject and how long until it expires. • Copy it raw or as "Bearer <token>". • Picks the right token automatically (refresh and expired tokens are skipped). You can also pin a source per site. RIGHT-CLICK MENU AND SHORTCUTS • Right-click any page › StorageNinja: copy the access token, copy Local Storage, Session Storage, Cookies or everything as JSON, paste from the clipboard, save or restore a snapshot, clear everything. • Alt+Shift+T copies the access token without opening the popup. Alt+Shift+S opens the popup. SNAPSHOTS • Save the storage and cookies of a site and restore them later, for example to switch between test users. • Snapshots stay on your computer. FULL COOKIE SUPPORT • Reads every cookie of the site, including HttpOnly, Secure, SameSite and Partitioned (CHIPS) cookies. • Edit name, value, domain, path, expiry and all flags. • Cookies copied from another environment (for example production) can be pasted into localhost; they move to the current site automatically. DETAILS VIEW AND DEVTOOLS PANEL • Search keys and values, edit JSON, decode JWTs, add and delete items. • Paste with Merge (keep existing data) or Replace (delete first). • Export and import .json files. • View IndexedDB databases and records, and Cache Storage entries. • Select an iframe to work with its storage. • The same view is available as a "StorageNinja" tab in Chrome DevTools. PRIVACY • Everything runs locally in your browser. StorageNinja has no server, no analytics and no remote code. • Data leaves the extension only when you copy it to the clipboard or export a file. • Privacy policy: https://osmnnl.github.io/StorageNinja/privacy-policy.html Open source: https://github.com/osmnnl/StorageNinja
