cookie-use

About

cookie-use captures your browser's authenticated state and exports it as a clean JSON file that works directly with Playwright, Puppeteer, and any tool that reads the StorageState format.

What it captures

- Cookies — including httpOnly cookies that JavaScript cannot read
- localStorage — per-origin key-value pairs
- IndexedDB — optional, for apps that store auth state in the browser database

How it works

1. Log into the site you want to automate
2. Click the cookie-use icon in your toolbar
3. Choose what to capture: cookies, localStorage, IndexedDB
4. Click Copy JSON or Download .json

The exported file is in Playwright StorageState format by default. Toggle off "Playwright format" to get the raw Chrome extension API format if your tooling expects that instead.

Permissions

- cookies — reads httpOnly and secure cookies that the page script cannot access
- activeTab — reads the current tab's URL to scope the capture
- scripting — runs a content script to capture localStorage and IndexedDB
- downloads — saves the .json file to disk when you use Download
- host permissions — requested per site, on demand. Chrome shows a dialog the first time you capture a site — you control which sites are granted access.

No data is sent anywhere. Everything stays on your machine.
