JS Analyzer by Faxcel

JS Analyzer is a Firefox extension designed to assist developers, security researchers, and anyone interested in analyzing JavaScript files directly within their browser. It automatically scans the JavaScript content on your active webpage to identify potential API keys, sensitive credentials like usernames and passwords, and URL endpoint patterns that might reveal internal API structures. By providing immediate visibility into exposed JavaScript information, JS Analyzer enhances security awareness and facilitates quick identification of crucial data that might have been unintentionally exposed. Its clean and organized pop-up interface displays findings in easily digestible categories: API, Credentials, and Endpoints/Misc, ensuring you can rapidly review and act on discovered information. It's an ideal tool for web security audits, reverse engineering, or simply understanding how web applications interact with backend services.
