CMS Detector: Find What Powers Any Website
Free CMS detector. Detect WordPress, Shopify, Wix, Joomla, Drupal and more from code fingerprints. Perfect for competitor research and client website audits.
Introduction
Have you ever visited a website and wondered what it was built with? Maybe a competitor's store loads suspiciously fast, or a client's blog has a layout you admire, or you are evaluating platforms for your own project and want real world examples. The content management system behind a website shapes everything: its speed, its SEO capabilities, its security profile, and how much it costs to maintain. Knowing which CMS powers a site is the fastest way to understand how it works.
The problem is that websites do not advertise their technology stack. The CMS is hidden behind the rendered page, buried in HTML source code, script paths, and HTTP headers that most people never inspect. You could dig through the source manually, but that takes time and expertise, and modern sites often hide or obscure the obvious clues.
The ZaxisMedia CMS Detector does the detective work for you. Enter any URL and it analyzes code fingerprints, script signatures, meta tags, and header patterns to identify WordPress, Shopify, Wix, Squarespace, Joomla, Drupal, and many more platforms in seconds. This tool is a favorite among web designers researching the competition, agencies auditing prospective clients, developers scoping migration projects, and curious site owners who want to know what the best sites in their niche are built on.

Picture a digital agency pitching a redesign to a regional furniture retailer. Before the first meeting, the agency's strategist runs the retailer's site and its three main competitors through the CMS Detector. The results are revealing. The retailer's own site runs on an outdated, heavily customized CMS that explains its slow load times and painful content updates. Two competitors run on Shopify with modern themes, which explains their fast checkouts and polished mobile experience. The third runs on WordPress with WooCommerce.
Armed with this intelligence, the agency walks into the pitch with a data backed recommendation instead of a guess. They can show the retailer exactly what platforms the market leaders use, estimate realistic migration paths, and explain why the current platform is holding the business back. They also flag that the retailer's outdated CMS version has known security issues, adding urgency to the proposal. The agency wins the project, and the CMS Detector's thirty seconds of work shaped the entire winning argument.
