Website Tech Stack Detector (by Domain or URL)

omnial/x402-tech-stack-detect

Given a domain or URL, returns the technologies detected on that site's public HTTP headers and HTML (CDN, security headers, analytics, e-commerce platform, CSS framework, and similar), each with a category, a confidence level, and the evidence type behind the detection, plus quick yes/no signals for common categories like chat widgets, payment processing, and marketing automation.
