Wappalyzer

Wappalyzer is a web technology profiler that identifies the software and services used by websites. It detects content management systems, eCommerce platforms, web servers, JavaScript frameworks, analytics tools, marketing automation platforms, payment processors, CRM systems, and many other components by analyzing page content, headers, and network requests. Users can enter a URL to see a detailed breakdown of the site’s technology stack, or run bulk lookups to analyze large lists of domains.

Beyond single-site profiling, Wappalyzer provides technology-based lead generation and market analysis capabilities. Users can create segmented lists of websites and associated contacts filtered by specific technologies, versions, or categories, supporting sales prospecting, competitive research, and partnership targeting. Browser extensions allow on-the-fly detection while browsing, and APIs and integrations enable automated enrichment of CRM and internal systems with technology data. Historical data and trends help users monitor technology adoption, migration patterns, and market share changes over time.
