How this service works
Detect the technologies a website uses from its headers and HTML: CMS (WordPress, Shopify, Webflow), frameworks (Next.js, React, Vue), CDN and hosting (Cloudflare, Vercel), analytics, chat, payments. Use for lead qualification, sales prospecting or competitor research.
Output
A structured list of detected technologies categorized by type (CMS, JavaScript framework, CDN/hosting, analytics, chat, payments), identified from the target website's HTTP response headers and HTML source. Each detected technology is typically named with its product identifier (e.g. WordPress, Next.js, Cloudflare, Google Analytics).
Example use cases
Qualify SaaS leads by tech stack
“I have a list of prospects and I want to know which ones are running WordPress so we can pitch our WordPress plugin — can you check techstackof shopify.com to start and tell me their CMS and any e-commerce platform they use?”
Competitor tech stack research
“Can you analyze stripe.com's tech stack and tell me what frontend framework, CDN, and analytics tools they're using? I'm doing competitive research.”
Sales prospecting filter by platform
“I'm targeting companies that use Shopify — can you check whether acme-retail.com is built on Shopify and what other tools like chat or analytics they have running?”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/web/tech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to identify the technology stack of any public website for purposes like lead qualification, sales prospecting, or competitive research. It is purpose-built for tech fingerprinting from HTTP headers and HTML, covering a wide range of categories (CMS, frameworks, CDN, analytics, payments, chat). Prefer this over general web scraping endpoints when the goal is specifically technology identification rather than content extraction.
Side effects
- URL is unreachable or returns an error — detection fails with no results
- Website uses heavy obfuscation or server-side rendering that hides technology signals — partial or empty results
- Domain resolves but returns a parked or redirect page — inaccurate or minimal detection
- Invalid or malformed URL input — request rejected with validation error
- Rate limiting or anti-bot protections on the target domain — may limit header/HTML retrieval
