A BuiltWith scraper for full website tech profiles
The Kavex BuiltWith scraper builds a detailed technology profile for every website on your list. For each site it returns the detected frameworks, CMS, analytics and payment tech, the server and CDN behind it, the security-header posture, and DNS infrastructure facts. It is built for competitive research, lead qualification and partner discovery — knowing what a company runs tells you how to sell to them.
Sign up to useWhat it does
Give it a list of websites and each one comes back as a single profile row.
The profile covers four layers. Application: detected frameworks, CMS, analytics, marketing, e-commerce and payment technologies. Infrastructure: the HTTP server, the CDN or edge provider, and the X-Powered-By stack. Security: whether HSTS and a Content-Security-Policy are present and the X-Frame-Options setting. Network: the hosting IP addresses, nameservers and mail provider from DNS.
Together that is enough to qualify a lead — a Shopify store versus a custom build, a site on Cloudflare versus bare hosting — without opening a single page by hand.
Use cases
- Sales qualification — filter a prospect list by the platform they run before you pitch an integration.
- Competitive research — map which technologies a set of competitors depend on.
- Agency prospecting — find sites on outdated stacks that are ready for a rebuild.
Frequently asked questions
How is this different from the Tech Stack Detector?
It shares the same detection engine but adds the server / CDN stack, security-header posture and DNS infrastructure — a fuller profile rather than just the application technologies.
What input does it take?
A plain list of website URLs or bare domains, one per line. Each returns one profile row.
Does it detect the CDN?
Yes — Cloudflare, CloudFront, Fastly, Akamai, Vercel, Netlify and others are identified from the response headers.
