## Description

JS Recon Buddy is a lightweight browser extension that scans a webpage using regex patterns to surface security-relevant information quickly. It identifies subdomains, endpoints and paths, potential secrets, DOM XSS sinks, interesting parameters, source maps, and JavaScript libraries found on the page.

If a valid source map is found, the extension attempts to deconstruct the original sources based on the map data. This tool is ideal for developers and security testers seeking fast reconnaissance directly in the browser.
