Wappalyzer - Technology profiler

Wappalyzer is a technology profiler that shows you what websites are built with. Find out what CMS a website is using, as well as any framework, ecommerce platform, JavaScript libraries and many more. Wappalyzer is more than a CMS detector or framework detector: it uncovers more than a thousand technologies in dozens of categories such as programming languages, analytics, marketing tools, payment processors, CRM, CDN and others. Use the export button to save results to CSV. The extension has a toggle for light and dark mode. Install Wappalyzer for Chrome to find out the technologies used on websites you visit at glance.
