FREE TOOL · TECH RADAR LITE
What is that website built with?
Enter any domain. We fetch the live page and fingerprint its stack — CMS, builder, frontend framework, CDN, hosting, analytics and payments. Free, no signup.
FAQ
What can the checker detect?
CMS platforms (WordPress, Ghost), site builders (Webflow, Framer, Wix, Squarespace), e-commerce (Shopify), frontend frameworks (Next.js, Nuxt, SvelteKit, Astro), CDN and hosting (Cloudflare, Vercel, Netlify, AWS), analytics, chat and payment widgets.
Is it really free?
Yes — 10 lookups per visitor per day, no account needed. Results for the same domain are cached for 24 hours.
How does it work?
We fetch the live homepage over HTTPS and match it against a fingerprint rule library (HTML markers and response headers). It is the free tier of our Tech Radar data surface; deeper history and alerts may ship later.
Can I call this from my own tools?
Yes — wordradar ships a REST API and an MCP server for AI agents, covering the keyword ledger, SERP difficulty, Trends risers and more. See the API docs.
