How this service works
Detect likely web technologies from a public page response headers and HTML signatures.
Output
Returns a list of detected web technologies inferred from HTTP response headers and HTML signatures of the target page, typically including server software, CMS platforms, JavaScript frameworks, CDN providers, analytics tools, and other detectable stack components.
Example use cases
Competitor tech stack research
“What technology stack is https://www.notion.so built on? I want to know their frontend framework, web server, and any analytics or CDN they're using.”
Pre-sales website audit
“Before my call with this prospect, can you quickly check what technologies their site https://acmecorp.com is running so I know their current setup?”
Security and infrastructure profiling
“Can you fingerprint https://www.reddit.com and tell me what server software, CDN, and frontend frameworks they're using based on their response headers and HTML?”
Technical details
Endpoint
GEThttps://x402-zoo.lolagent.workers.dev/api/website-techWhen to prefer
Use this endpoint when you need a lightweight, cost-effective way to fingerprint a public website's technology stack without running a full crawl or browser automation. Ideal for competitive intelligence, pre-sales research, or automated audits where you need quick tech detection from headers and HTML alone. Prefer this over browser-based alternatives when speed and low cost matter more than deep JS-rendered detection.
Side effects
- Target URL is not publicly accessible or returns a non-200 status
- Website blocks bot user agents or returns minimal headers, reducing detection accuracy
- HTTPS/TLS issues on the target site prevent fetching
- Missing or empty `url` query parameter causes a validation error
- Detection limited to signature-based heuristics — some technologies may go undetected if they leave no fingerprint
