WhosBuilt
Wappalyzer alternative

A Wappalyzer alternative for evidence-first website research

Run a web-based report for one domain: stack clues, hosting, DNS, headers, SSL, creator hints, contact paths, confidence, and freshness context.

Try:

What this checks

  • No browser extension required; WhosBuilt uses public web and DNS signals
  • Technology, hosting, headers, DNS, SSL, registrar, and contact evidence
  • Confidence context instead of raw detections with no trail

How I treat the evidence

Wappalyzer is useful for quick technology fingerprints. WhosBuilt is narrower and more investigative: it keeps the evidence trail visible for one-domain research.

That matters when raw detections are stale, a backend is hidden, or the real prospecting question is who built the site and how to reach them.

Is this a Wappalyzer database replacement?

No. Use WhosBuilt when you need a small number of verified public evidence reports, not a broad technographic database.

Does WhosBuilt track browsing through an extension?

No. The lookup runs from a domain you enter and uses public signals such as HTML, DNS, headers, certificates, robots files, and visible contact clues.
