How to Identify the Platform Behind Any Website

Understanding which system powers a website can reveal whether it's custom-built, running on a CMS like WordPress, or using a drag-and-drop service such as Wix or Squarespace. This insight is crucial for developers analyzing competition or users assessing website capabilities.

To determine the underlying technology, one can rely on browser inspection tools, online analysis services, or specific structural and code-based clues embedded within the site's HTML.

Key Techniques for Platform Detection

  1. Inspect the source code: Right-click on the page and choose "View Page Source" or press Ctrl+U. Look for meta tags, comment patterns, or asset URLs (e.g., /wp-content/ indicates WordPress).
  2. Use developer tools: Open browser developer tools with F12 and analyze network requests or cookies. For example, Shopify may set cookies like _shopify_y.
  3. Check the page footer: Many platforms include branded footers like "Powered by Shopify" or "Created with Wix."
  • Wix: Often has URLs containing wixstatic.com and inline scripts with wix-code.
  • Squarespace: Uses paths like /config/ and embeds static.squarespace.com in assets.
  • WordPress: Easily spotted via /wp-* folder structure and generator meta tags.

Always cross-check multiple indicators. A single clue might be misleading, but a combination often confirms the platform.

Platform Common Indicators
WordPress /wp-content/, wp-json, generator: WordPress
Shopify cdn.shopify.com, cookies like _shopify_s
Wix wix.com domains, inline wix-code scripts

Top Techniques to Identify Website Creation Platforms Without Viewing Source Code

Understanding which platform a website was built on can provide valuable insights for developers, marketers, and competitors. Even when direct access to the page's source code is restricted, several strategic methods allow for accurate detection of the underlying website builder.

Platform Indicator Detection Method
Wix Static assets from wixstatic.com Network panel analysis
Squarespace Custom JSON endpoints API call inspection
Shopify Unique CDN and headers Header sniffing

Note: These techniques are legal and rely on publicly available information. They do not involve intrusion or unauthorized access.

Common Signs of Popular Website Builders (Wix, Shopify, Squarespace)

Each major website builder leaves behind distinctive technical and visual footprints. By examining elements like URL structure, source code, and backend behavior, it becomes possible to identify which platform powers a given website. This can be especially useful for developers, marketers, or analysts looking to assess competition or platform capabilities.

Below are specific characteristics frequently found in websites created with Wix, Shopify, and Squarespace. These include metadata patterns, embedded scripts, and recognizable frontend design patterns. Understanding these markers can help distinguish between these platforms quickly and effectively.

Platform-Specific Indicators

  • Wix: Often uses URLs containing "/_site/" and loads resources from "static.wixstatic.com".
  • Shopify: Commonly includes "cdn.shopify.com" assets and meta tags like "shopify-checkout-api-token".
  • Squarespace: Loads JavaScript files from "static.squarespace.com" and includes structured data in JSON-LD format related to design settings.

Wix pages typically show large inlined CSS and JavaScript blocks in the source code, reflecting its focus on visual editing flexibility.

Platform URL Pattern Unique Asset Host
Wix /_site/, /post/, /product-page/ wixstatic.com
Shopify /products/, /collections/ cdn.shopify.com
Squarespace /config/, /index/ static.squarespace.com
  1. Check the page source for platform-specific JavaScript files.
  2. Inspect the network tab for CDN hosts used by the site.
  3. Review meta tags and structured data in the header section.

Shopify websites often reveal their origin via hidden input fields tied to shopping cart functions and checkout URLs.

Using Developer Tools to Identify Website Platform Traces

Modern browsers provide built-in inspection tools that can reveal underlying technologies used by websites. By opening the developer console (usually via F12 or right-click → Inspect), users can examine HTML structure, loaded resources, and HTTP headers to detect specific platform signatures such as plugins, themes, and template engines.

Traces of content management systems often appear in predictable patterns within source code. File paths, meta tags, and JavaScript variables can all indicate the builder behind a site. Inspecting these elements manually is a reliable method to identify a CMS even if automatic detection tools fail.

Manual Clues Within Developer Tools

  • Look for HTML comments referencing a platform (e.g., “”).
  • Check meta tags such as <meta name="generator" content="WordPress 6.4.2">.
  • Review file paths in the Network tab – /wp-content/ or /sites/default/files/ reveal WordPress or Drupal respectively.
  • Identify JS/CSS files with distinctive naming patterns (e.g., shopify.min.js).

Tip: CMS-specific admin URLs (e.g., /wp-admin/, /administrator/) often return redirect or error messages but still confirm the platform.

  1. Open browser dev tools.
  2. Navigate to “Elements” and “Network” tabs.
  3. Search for keywords like “wp-”, “drupal”, “joomla”, etc.
  4. Analyze HTTP response headers for platform hints.
Clue Type Example Likely Platform
Meta Tag <meta name="generator" content="Joomla!"> Joomla
File Path /wp-content/plugins/ WordPress
JS File cdn.shopify.com Shopify

Limitations of Automated Website Builder Detection Tools

Automated tools designed to identify website builders often rely on certain patterns and signatures that are typical of specific platforms. While these tools can offer quick insights into the website's construction, they do have notable limitations. Many website builders are constantly evolving, and these tools may not keep pace with updates or modifications in the builder's code. This creates gaps in the tool’s accuracy, as newer versions of builders or customizations made to templates can be missed or misinterpreted.

Additionally, websites that use custom designs or have been heavily modified may not display the typical characteristics that automated detection tools look for. This makes it challenging for the tool to correctly identify the platform. Moreover, some websites may deliberately hide or alter these identifiers to protect their use of a particular builder, adding another layer of complexity for detection systems.

Key Issues with Detection Tools

  • Outdated Patterns: Many detection tools rely on old, predefined patterns that may no longer apply to current website builder versions.
  • Customization Complexity: Heavily customized sites can bypass tool detection due to unique or altered coding practices.
  • False Positives: Some tools may incorrectly attribute a site to a certain builder when custom frameworks or mixed technologies are used.

It’s important to understand that these tools are not always definitive. Manual verification is often required for accurate identification of the website’s builder.

Detection Accuracy Across Platforms
