StashView

Developer-focused storage inspector: localStorage, sessionStorage, cookies, and IndexedDB — right in DevTools.

StashView — Developer Storage Inspector Inspect, edit, and delete browser storage without opening DevTools. StashView puts localStorage, sessionStorage, cookies, and IndexedDB right in your Chrome toolbar — one click, instant results. --- WHY STASHVIEW? Every web developer has been there: you need to check a localStorage token, clear a stale cookie, or peek at an IndexedDB record — and instead you're digging through DevTools → Application → Storage → expand tree → wait. StashView collapses all of that into a single toolbar click. --- WHAT YOU CAN INSPECT 📦 localStorage List, search, view, edit, and delete entries for the current page. JSON values auto-expand into a collapsible, syntax-highlighted tree so you can read nested data at a glance. ⚡ sessionStorage Full read/write access to session-scoped storage, isolated per tab — useful for debugging auth flows and ephemeral state. 🍪 Cookies See every cookie for the current domain with all flags exposed: HttpOnly, Secure, SameSite, domain, path, and expiry. Edit non-HttpOnly cookies inline without writing a single console command. 🗄 IndexedDB Drill down from databases → object stores → individual records in a clean tree view. Inspect and delete records without opening the Application panel. --- JSON-FIRST VALUE HANDLING StashView auto-detects JSON strings and renders them as interactive, collapsible trees with One Dark syntax highlighting — strings, numbers, booleans, and nulls are all colour-coded for fast scanning. Toggle between parsed tree and raw string views. Copy any nested value to the clipboard in one click. --- BUILT FOR PRIVACY StashView makes zero network requests. Your storage data is read from the active tab and displayed locally in the popup — it never leaves your browser. There is no telemetry, no analytics, no crash reporting, no CDN-loaded scripts, and no external servers of any kind. The extension works fully offline. Permissions used: • activeTab & scripting — to read storage from the page you're inspecting • cookies — to list and edit cookies for the current domain • storage — to persist your UI preferences (theme, last-used tab) • tabs — to know which tab is active --- ZERO SETUP No account. No sign-in. No configuration required. Install, click the icon on any page, and your storage data is right there. --- OPEN SOURCE StashView is open source.
