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.
