LocalStorage Manager

View, edit, search, and export localStorage and sessionStorage entries for any page.

View, edit, search, and export localStorage and sessionStorage entries for any page. LocalStorage Manager gives you a clean popup to inspect and manage all client-side storage on the current page — no more digging through DevTools Application panel. How it works: 1. Click the extension icon on any page. 2. See all localStorage entries in a searchable, sortable table. 3. Switch to the sessionStorage tab for session data. 4. Click any value to edit it inline. Add, delete, or clear entries. Features: - Two tabs — switch between localStorage and sessionStorage. - Searchable table — filter entries by key or value instantly. - Inline editing — click any value to edit, press Enter to save. - Add new entries — create new key-value pairs with one click. - Delete entries — remove individual entries or clear all with confirmation. - Size info — see data size per key and total storage used. - Export and import — save all entries as JSON, import from a JSON file. - One-click copy — copy any value to clipboard. - Auto-refresh — detects storage changes every 3 seconds without interrupting edits. - 100% local — no data leaves your browser. No accounts, no tracking, no servers. Who is this for? - Frontend developers debugging SPA state and auth tokens. - QA engineers verifying client-side data between test steps. - Anyone who wants a faster way to view and edit browser storage. Privacy: LocalStorage Manager does not collect, transmit, or share any data. It reads storage only from the active tab when you click the icon. No analytics, no telemetry, no third-party services.
