DetectZeStack — Website Intelligence API - 7 website intelligence tools in 1 affordable API

Hey Product Hunt! I'm Michael, and I built DetectZeStack because I got tired of the absurd pricing in the website intelligence space. The problem: I needed an API to detect what technologies websites use — frameworks, CDNs, analytics, CMS, payment processors. BuiltWith charges $295/mo minimum. Wappalyzer starts at $250/mo. For most developers, those prices are a non-starter. Since our first launch here in February, DetectZeStack has grown from a single tech detection endpoint into a full website intelligence suite with 7 tools: 1. Tech Stack Detection — 7,200+ technologies via Wappalyzer + DNS + TLS + HTTP 2. Batch Analysis — up to 10 URLs per request 3. Tech Stack Comparison — side-by-side across sites 4. SSL/TLS Certificate Check — full cert inspection 5. DNS Intelligence — all record types + provider enrichment 6. Security Header Analysis — A+ to F grading 7. Change Monitoring — webhooks when stacks change What makes it different: CPE identifiers for vulnerability lookups, multi-signal detection that catches infrastructure HTML scanners miss, and pricing that starts at $0. There's also a free Chrome extension on the Web Store. I'm a solo founder — network engineer by day, indie maker by night. Would love your feedback: what features would make this more useful?
