Detect the technologies behind any website (BuiltWith-style): CMS, frameworks, CDN/hosting, analytics, server, payments. Evidence included.

Detect the technologies a website uses (CMS, frameworks, analytics, CDN, web server, ecommerce, tag managers ...) from its HTML, headers, cookies, meta tags and script URLs, matched against 7,600+ open webappanalyzer fingerprints. Returns name, categories, version where visible, confidence and evidence, plus a by-category summary. Params: url (required), min_confidence (0 to 100, default 50).

Detects the technologies of a website homepage (CMS, e-commerce, frameworks, web server, CDN/hosting, analytics, tag managers, ad pixels, payments, chat, consent, security headers, fonts) with category, version when visible, evidence and confidence.

For a URL and a technology, passively detects the tech and its version (headers, meta generator, script URLs - read-only, no probing), looks that version up in public CVE databases (OSV/NVD), and reports known CVEs plus a security-header posture. For assets you own or are authorized to test. Up to 3 items per call; failed lookups are not charged.
