Website Tech Stack Checker
Instantly detect the Frameworks, Hosting, Analytics, and Tools Powering your competitors' website.
Free website technology lookup for research and benchmarking
Use this page to answer practical questions: Is this site on WordPress or a headless CMS? Which analytics and tag managers appear in the page? What CDN or edge network fronts their HTML? The checker scores each detection so you can see how confident the match is before you rely on it in a report or slide deck.
Product teams pair these signals with broader competitive intelligence—for example, noticing when a rival adds a new A/B testing tool or migrates hosting—so you can prioritize your own roadmap and messaging. Journalists and SEOs use the same fingerprints to verify claims about how a company's site is built without asking their engineering team.
