BuiltWith is a web-based technology profiler and competitive intelligence platform. It scans websites and reveals what tech they’re built with — CMS, eCommerce platform, web servers, analytics, frameworks, advertising tools and more. You can look up sites directly in the browser or via the API.
Understanding which technologies a website uses helps sales teams find prospects, marketers tailor outreach, developers compare stacks, and analysts track market adoption trends across millions of sites. BuiltWith supports lead generation, competitive analysis, and strategic decision-making.
Enter a URL or upload a list of domains to get detailed tech stack reports. You can filter results by technology, industry, location, or traffic. BuiltWith also offers browser extensions to quickly inspect live sites and APIs for automated workflows.
