How WhosBuilt finds builder signals

Some sites leave direct credits: a footer link to an agency, a humans.txt file, an author tag, or structured data naming an organization. Other sites only expose indirect clues, such as a CMS generator tag, CDN headers, hosting DNS, analytics scripts, domain age, Wayback history, registrar data, or SSL certificate details.

WhosBuilt combines those signals into one scan so you can move from "who built this website?" to a practical answer: who likely owns or built it, which evidence supports that, where it is hosted, and which public contact path is visible.

When to use it

  • Qualify rebuild prospects before outreach
  • Find the agency, vendor, or maker behind a site
  • Turn competitor domains into evidence-backed lead notes
  • Check whether a site exposes enough public contact paths

If you mainly need framework, CMS, hosting, or CDN details, use the website tech stack checker. For the broader report, use what is this website built with.
