Summary
Gives Claude programmatic access to website intelligence data including technology stacks, hosting providers, security configurations, SEO metrics, and DNS records. The kind of tool you'd reach for when building competitive analysis workflows, automating tech stack research, or enriching lead data with hosting and security details. Built by the creator of toolcompare.fyi, so it's likely pulling from similar APIs that power site analysis tools. Think of it as giving your agent the ability to answer "what's this site running on" without you manually checking BuiltWith or SecurityHeaders. Useful for market research, sales intelligence, or any workflow where you need to programmatically inspect domain infrastructure and technical posture.
