How Can You Tell What Platform a Website Is Built On: A Deep Dive into the Digital Footprints

In the vast expanse of the internet, websites are the digital storefronts of businesses, the portfolios of creatives, and the platforms for information dissemination. But have you ever wondered what lies beneath the surface of these websites? Specifically, how can you tell what platform a website is built on? This question is not just a matter of curiosity but also a practical concern for developers, marketers, and even casual users who want to understand the technology stack behind a site.

1. Inspecting the Source Code

One of the most straightforward methods to determine the platform a website is built on is by inspecting its source code. By right-clicking on a webpage and selecting “View Page Source” or “Inspect,” you can access the HTML, CSS, and JavaScript that make up the site. Look for telltale signs such as specific meta tags, comments, or script references that might indicate the use of a particular platform.

For example, WordPress sites often include meta tags like <meta name="generator" content="WordPress">. Similarly, Joomla sites might have comments in the source code that mention “Joomla” or specific Joomla-related scripts.

2. Analyzing the URL Structure

The URL structure of a website can also provide clues about the platform it’s built on. Certain platforms have distinct URL patterns. For instance, WordPress sites often have URLs that include /wp-content/ or /wp-admin/, while Drupal sites might have URLs that include /sites/default/files/.

Additionally, some platforms use specific file extensions or directory structures that can be identified in the URL. For example, a URL ending in .aspx might indicate that the site is built on Microsoft’s ASP.NET framework.

3. Using Online Tools and Services

There are several online tools and services designed to help you identify the platform a website is built on. Tools like BuiltWith, Wappalyzer, and WhatCMS can analyze a website and provide detailed information about the technologies used, including the content management system (CMS), web server, programming languages, and more.

These tools work by scanning the website’s code, headers, and other elements to detect patterns and signatures associated with specific platforms. They can be particularly useful for quickly identifying the platform without needing to delve into the source code manually.

4. Examining the HTTP Headers

HTTP headers are another valuable source of information about a website’s platform. When a browser requests a webpage, the server responds with HTTP headers that contain metadata about the response. Some of these headers can reveal the server software, programming language, and even the CMS being used.

For example, the X-Powered-By header might indicate the server software (e.g., X-Powered-By: PHP/7.4.3), while the Server header might reveal the web server (e.g., Server: Apache/2.4.41 (Ubuntu)). These headers can be viewed using browser developer tools or online services like Header Checker.

5. Checking for Platform-Specific Features

Different platforms often come with their own set of features, plugins, and themes that can be identified by their appearance or functionality. For example, WordPress sites frequently use plugins like Yoast SEO, which adds specific meta tags and structured data to the site. Similarly, Shopify sites often have a shopping cart icon and a checkout process that is distinct to the platform.

By examining these features, you can often make an educated guess about the platform a website is built on. For instance, if a site has a drag-and-drop page builder interface, it might be using a platform like Wix or Squarespace.

6. Looking at the Website’s Footer

The footer of a website is a common place where developers or site owners might include information about the platform or CMS used. It’s not uncommon to see phrases like “Powered by WordPress” or “Built with Joomla” in the footer section. While this information isn’t always present, it’s worth checking as it can provide a quick and easy way to identify the platform.

7. Analyzing the Website’s Performance and Behavior

The performance and behavior of a website can also offer insights into the platform it’s built on. For example, WordPress sites often have a slower initial load time due to the extensive use of plugins and themes. On the other hand, static site generators like Jekyll or Hugo tend to have faster load times because they generate static HTML files.

Additionally, certain platforms have specific behaviors, such as how they handle caching, redirects, or error pages. By observing these behaviors, you can sometimes infer the underlying platform.

8. Reviewing the Website’s Documentation or Help Pages

If the website has documentation or help pages, these can be a goldmine of information about the platform. Many platforms provide documentation that includes details about the CMS, themes, plugins, and other technologies used. For example, a WordPress site might have a “Help” section that links to WordPress.org documentation, while a Shopify site might have a “Support” section that links to Shopify’s help center.

9. Checking for Platform-Specific Files and Directories

Certain platforms create specific files and directories that can be accessed directly through the browser. For example, WordPress sites often have a wp-login.php file that can be accessed to log in to the admin dashboard. Similarly, Joomla sites might have a administrator directory that can be accessed to log in to the backend.

By attempting to access these files or directories, you can sometimes confirm the platform a website is built on. However, it’s important to note that some site owners may restrict access to these files for security reasons.

10. Using Browser Extensions

There are several browser extensions available that can help you identify the platform a website is built on. Extensions like Wappalyzer, BuiltWith Technology Profiler, and WhatRuns can be installed in your browser and will automatically detect and display the technologies used by the websites you visit.

These extensions work by analyzing the website’s code, headers, and other elements in real-time, providing you with instant information about the platform and other technologies used.

11. Examining the Website’s Robots.txt File

The robots.txt file is a text file that webmasters create to instruct web robots (typically search engine robots) on how to crawl and index pages on their website. This file can sometimes contain information about the platform or CMS used.

For example, a WordPress site might have a robots.txt file that includes directives like Disallow: /wp-admin/ or Disallow: /wp-includes/, which are specific to WordPress. By examining this file, you can sometimes identify the platform.

12. Looking for Platform-Specific Cookies

Cookies are small pieces of data stored on a user’s device by a website. Some platforms set specific cookies that can be used to identify the platform. For example, WordPress sets cookies like wordpress_logged_in_ and wp-settings- for logged-in users.

By examining the cookies set by a website, you can sometimes determine the platform it’s built on. Browser developer tools or extensions like EditThisCookie can help you view and analyze the cookies set by a website.

13. Checking for Platform-Specific Error Messages

When something goes wrong on a website, the error messages displayed can sometimes reveal the platform. For example, a WordPress site might display a “White Screen of Death” or an error message that includes the term “WordPress.” Similarly, a Drupal site might display error messages that reference “Drupal” or specific Drupal modules.

By paying attention to these error messages, you can sometimes identify the platform a website is built on.

14. Analyzing the Website’s Database Structure

For those with access to a website’s database, the structure of the database can provide clues about the platform. Different platforms use different database schemas, table names, and structures. For example, WordPress uses tables like wp_posts, wp_users, and wp_options, while Joomla uses tables like jos_content, jos_users, and jos_modules.

By examining the database structure, you can sometimes determine the platform a website is built on. However, this method requires access to the website’s database, which is typically restricted to site administrators.

15. Reviewing the Website’s API Endpoints

If a website has an API, the endpoints and the structure of the API responses can sometimes reveal the platform. For example, a WordPress site might have API endpoints like /wp-json/wp/v2/posts or /wp-json/wp/v2/users, while a Shopify site might have endpoints like /admin/api/2021-10/products.json.
