Extract JavaScript from Any Website
Curious about how a website works? Download all JavaScript files from any page. Our script extractor captures external JavaScript files, inline <script> blocks, and dynamically loaded modules. Useful for learning from production implementations, debugging issues, security auditing, analyzing third-party scripts on your own site, or understanding how modern web applications are architected.

Why Extract JavaScript from Websites?
JavaScript powers modern web applications, and understanding how production sites implement their functionality is invaluable for developers. Our JavaScript extractor gives you direct access to the client-side code running on any website. The extraction process is comprehensive. We capture externally linked script files, inline code embedded in the HTML, and even scripts loaded dynamically after page load. Modern bundled applications from Webpack, Vite, Rollup, and other build tools are fully captured as their final production bundles. For security professionals, this tool is essential for pentesting and vulnerability assessment. See exactly what code runs on the client, identify potential XSS vectors, understand authentication flows, and analyze API interactions. For developers, study how leading companies structure their front-end code, learn from real-world implementations, and debug issues by comparing with working examples. Remember: extracting is for learning and security research - respect copyrights and don't reuse proprietary code.
