StashView puts localStorage, sessionStorage, cookies and IndexedDB inspection right in your Chrome toolbar — no DevTools required. Built for developers who want answers fast.
What's inside
No more opening DevTools, navigating Application panels, and waiting for the tree to load. StashView surfaces everything instantly.
List, search, view, edit and delete entries. JSON values auto-expand into a collapsible syntax-highlighted tree.
persistentSame full editing experience as localStorage, scoped to the current browser tab session.
tab-scopedInspect all cookie flags — HttpOnly, Secure, SameSite, domain, path, expiry. Edit non-HttpOnly cookies inline.
flags visibleBrowse databases → object stores → records in a drill-down tree. View and delete individual records.
structured dataJSON first
StashView auto-detects JSON and renders it as an interactive tree with One Dark syntax highlighting — strings, numbers, booleans, nulls all colour-coded. Toggle between tree and raw views. Copy any nested value to clipboard in one click.
Getting started
Click "Add to Chrome". No signup, no account — just the extension.
Navigate to any website and click the StashView icon in your Chrome toolbar. The popup opens instantly.
Browse storage tabs, click a key to expand its value, edit or delete entries, and filter by key name.
StashView reads storage data from the current tab and displays it locally in the popup. There are no external network requests, no analytics, no crash reporting, no CDN scripts — nothing leaves your browser. Ever.
