How this service works
Detect the technologies behind a website: CMS (WordPress, Shopify...), frameworks (Next.js, React...), server and CDN, analytics, payments, chat, cookie manager, captcha and fonts, from HTML and headers. For lead generation and competitive research.
Output
Returns a JSON object with: the detected server software (e.g. nginx), CMS name (e.g. WordPress with version), analytics tools (e.g. Google Tag Manager), content sources (e.g. Google Fonts), a count of total technologies found, the final resolved URL after redirects, and a note that detection is based on HTML signatures and headers without JavaScript execution.
Example use cases
CMS identification for competitor research
“I'm researching competitors in the e-commerce space — can you tell me what CMS and technology stack https://www.shopify.com/ is running on, including any analytics or third-party sources?”
Pre-migration tech audit
“Before I migrate this client's site, can you detect what server software, CMS, and analytics tools are currently running on https://example-client.com?”
Lead enrichment for agency outreach
“I'm building a list of WordPress sites to target with our plugin — can you check whether https://targetsite.com is using WordPress and what server it's on?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/tech-detect?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, lightweight technology fingerprinting of a website without browser JavaScript execution — ideal for bulk lead enrichment, competitor research, or pre-audit checks. Prefer this over full browser-based crawlers when speed and cost matter and dynamic JS-rendered content is not required.
Side effects
- URL unreachable or returns non-200 status — detection may fail or return partial results
- Technologies loaded only via JavaScript will not be detected (static analysis only)
- Heavily obfuscated or custom stacks may not match any known signatures
- Rate limiting or bot protection on target site may block the request
- Invalid URL format in input causes request validation error
