How many websites use Optimizely?
DetectZeStack has detected 39 websites using Optimizely. This count is based on our continuously updated scan database and grows as new sites are analyzed.
What websites are built with Optimizely?
The full list is shown above. Each site was verified through multi-layer detection including HTTP response headers, HTML content analysis, DNS record lookups, and TLS certificate inspection.
How do you detect Optimizely on a website?
DetectZeStack uses four detection methods that work together: HTTP header fingerprinting, HTML/JavaScript pattern matching, DNS CNAME and TXT record analysis, and TLS certificate inspection. This catches technologies that browser-only tools like WhatRuns or Wappalyzer miss entirely.
