CMS Detector
Identify the content management system, JavaScript framework, and server technology behind any website.
What This Tool Detects
A comprehensive analysis of the technology stack behind any website.
CMS Detection
Identifies popular CMS platforms like WordPress, Shopify, Wix, Squarespace, Joomla, Drupal, Ghost, and Webflow.
JavaScript Frameworks
Detects front-end frameworks including React, Vue.js, Angular, Svelte, jQuery, and CSS frameworks like Bootstrap and Tailwind.
Server Technology
Reads HTTP response headers to identify the web server (Nginx, Apache), language (PHP, ASP.NET), and CDN (Cloudflare).
Static Site Generators
Recognizes modern SSGs and meta-frameworks like Next.js, Gatsby, Hugo, and other popular build tools.
Confidence Scoring
Each detection comes with a confidence level (High, Medium, Low) based on how many matching patterns were found.
How It Works
Three simple steps to identify the technology behind any website.
Enter a URL
Type or paste any website URL. The tool accepts domains with or without the https:// prefix.
Analyze the Source
The tool fetches the page HTML and response headers, then scans for known CMS signatures, framework markers, and server identifiers.
View Results
See the detected CMS with confidence level, a list of technologies found, server details, and the meta generator tag if present.

Frequently Asked Questions
Common questions about CMS detection and website technology analysis.
How does CMS detection work?
The tool fetches the website's HTML source and HTTP response headers, then searches for known patterns unique to each CMS. For example, WordPress sites typically include /wp-content/ and /wp-includes/ paths, while Shopify sites load assets from cdn.shopify.com. The more patterns matched, the higher the confidence level.
Can the tool detect custom-built websites?
If a website is built from scratch without a known CMS or framework, the tool will report that no CMS was detected. However, it may still identify the underlying server technology (like Nginx or Apache) and any JavaScript libraries loaded on the page.
Why does the tool show Low confidence for some detections?
A Low confidence rating means only one matching pattern was found. This can happen when a site uses a CMS but has heavily customized its output, or when a single pattern (like a common file path) coincidentally matches. High confidence requires multiple independent signals pointing to the same CMS.
Is it possible for the detection to be wrong?
Yes, in rare cases. Some sites may include third-party scripts or assets that create false positives. For example, a site embedding a WordPress blog via iframe might trigger WordPress detection on the outer page. The confidence level helps indicate how reliable each detection is.
