I built PageData because of a problem I kept hitting from my marketing background - needing structured data about URLs. What tech stack is this site running? What are their OG tags? Is their SSL valid? Who handles their DNS? Every time, I'd cobble together 3-4 different APIs or libraries. One for metadata, one for tech detection, one for DNS, one for SSL. Each with its own auth, pricing, and response format. It was tedious. So I built one API that does it all. One request, one JSON response, four data layers. The approach evolved a lot during the build. I started with just metadata extraction, but quickly realized the real value was combining everything into a single call. The tech detection alone covers 7,000+ technologies via Wappalyzer fingerprints - that's a capability BuiltWith charges $295/mo for. I built it on Cloudflare Workers so it's fast from anywhere, and the free tier is real - 100 calls/month, no credit card, takes 10 seconds to get a key. The live demo on the homepage runs a real API call so you can test before signing up. Would love your feedback on what data you'd want added next.
