Detect 1000+ technologies on any website instantly
Wappalyzer is a powerful technology profiler that reveals the tech stack behind any website you visit. With over 1 million users and a 4.6/5 rating, it's become the industry standard tool for competitive analysis, sales intelligence, and web development research. Simply click the extension icon, and Wappalyzer instantly displays all detected technologies—from CMS platforms and eCommerce solutions to analytics tools, hosting providers, and JavaScript frameworks.
The extension's database includes over 1000 different technologies across 100+ categories. Whether you're analyzing a competitor's website to understand their tech choices, researching potential clients for sales outreach, or exploring how popular sites implement specific features, Wappalyzer gives you instant insights without requiring any technical setup or API calls.
Wappalyzer works by analyzing multiple data sources: HTML structure, JavaScript libraries, HTTP headers, DNS records, and even visual patterns. It can identify not just the obvious technologies (like WordPress or Shopify) but also the subtle ones—specific analytics platforms, A/B testing tools, customer support widgets, payment gateways, and even the exact version numbers of frameworks and libraries being used.
The free browser extension provides basic technology detection for the websites you visit manually. Wappalyzer Pro ($149/month) unlocks advanced features like bulk lookups (analyze thousands of URLs), API access for programmatic detection, CRM integrations, technology trend reports, and email alerts when competitors adopt new technologies. For sales teams, marketers, and developers who need to analyze tech stacks at scale, the Pro version becomes an essential competitive intelligence tool.
