What it does
REST API that identifies what technologies any website uses. Pass a URL, get back the full stack — frameworks, CMS, CDNs, analytics, and more. 4 detection methods in a single call: Wappalyzer fingerprinting (3,500+ signatures), DNS CNAME analysis, TLS certificate inspection, and HTTP header matching. Batch analysis (10 URLs), stack comparison, CPE identifiers for vulnerability mapping, and 24h smart cache. Free tier: 100 req/month.
Monitor, compare, and analyze technology stacks in real time. 7,300+ technologies, change tracking, webhook alerts, batch analysis. Free tier available.
Detect what any site runs, track changes over time, compare competitors side by side, and get alerted when stacks shift. One API, full visibility. All features included in the free tier. 100 requests/month free, no credit card → Instant single-URL checks. For batch lookups or programmatic use, grab an API key. Paste any URL — see whether the site uses Cloudflare, Fastly, Akamai, AWS CloudFront, Vercel, Netlify, or another CDN. Paste a competitor's URL — see their full tech stack: frameworks, CMS, analytics, CDN, ad networks, A/B testing. Paste any URL — find out if it runs WordPress, Drupal, Joomla, Shopify, Wix, Squarespace, Webflow, Ghost, or another CMS. Paste any URL — see if it's…from detectzestack.com
