LocalStorage Manager

About

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.
