StackScan: Search 100M+ websites by tech stack, keyword & intent

StackScan is a technographic intelligence platform that helps you discover websites by the technologies they use, keywords they rank for, and topics they cover. Search across 100M+ websites and 50,000+ tracked technologies, filter by country, TLD, traffic, and company data, then export highly targeted prospect lists for sales, marketing, research, security, and competitive analysis. Think BuiltWith meets lead generation, without the enterprise price tag.

Hey Product Hunt 👋 I'm excited to introduce StackScan. Over the last few years, I've used tools like BuiltWith, Wappalyzer, and Others for prospecting, competitor research, and market analysis. While powerful, many of them are priced for large teams and enterprises. StackScan was built to make technographic intelligence more accessible. With StackScan, you can: - Find websites using specific technologies (Shopify, WordPress, HubSpot, React, and 50,000+ others) - Search websites by keywords, niches, and topics - Filter by country, TLD, traffic, company size, and more - Export targeted lead lists for outreach and research - Analyze technology adoption across millions of websites Today we're tracking 100M+ domains and 50,000+ technologies, and we're continuously expanding coverage and improving detection quality. We're also offering an early-adopter lifetime deal while we're still in the growth phase. I'd love to hear your feedback, feature requests, and use cases. What would you use StackScan for? Thanks for checking it out and supporting the launch!

Is this a Builtwith alternative? Or do you rely on methods other than Frontend? How come is it offered as a lifetime deal? The data side of this product seems significantly harder than the UI side. How are technologies actually detected? Are you relying on JavaScript signatures, HTML patterns, HTTP headers, DNS records, script sources, or a combination of signals?
