Ever landed on a website and thought, “How did they build this?” Maybe you’re planning your own site, looking at competitors, or just curious about the tech behind a design you love. The big question is: how do you find out what CMS a website is using?
Good news, you don’t need to be a developer or hacker to figure it out. With the right tools and a bit of curiosity, you can discover the content management system (CMS) behind almost any website.
Let’s break it down step-by-step in a way that’s simple, practical, and useful.
What Is a CMS (and Why Should You Care)?
A Content Management System (CMS) is software that helps people create and manage websites without needing to write all the code from scratch. Instead of dealing with complex code, you can use an easy dashboard to add pages, upload images, publish blog posts, and manage your entire site.
Popular CMS platforms include WordPress, Shopify, Joomla, Drupal, and more. Each platform is designed for different needs; some work better for blogging, while others are made specifically for eCommerce or large-scale websites.
Understanding what CMS a website uses can help you:
- Learn from competitors by analyzing how their site is structured and managed
- Choose the right platform for your own site based on real-world examples
- Analyze performance and SEO strategies tied to specific CMS platforms
- Discover plugins, themes, or features used to enhance functionality
- Understand how easy (or complex) it might be to replicate similar designs or features
Knowing the CMS behind a website provides valuable insights into how it is built, maintained, and optimized. Using a CMS checker can speed up this process and make it more accurate without changing the overall approach.
Step-by-Step Guide to Finding a Website’s CMS
Start simple. Scroll to the bottom of the website. Many sites proudly show their CMS with text like:
- “Powered by WordPress”
- “Built with Shopify”
Sometimes, this text may also include theme or developer credits.
It’s not always there. When it is, it’s an easy win. Remember that some websites remove or change this footer text, especially if they want a more branded or professional look.
2. View Page Source (Quick Manual Check)
This sounds technical, but it’s actually easy.
How to do it:
- Right-click anywhere on the page
- Click “View Page Source”
- Press Ctrl + F (or Cmd + F on Mac)
Now search for keywords like:
- wp-content (WordPress)
- shopify
- drupal
- joomla
If you see these terms in URLs, file paths, or scripts, you’ve likely found your CMS. For example, WordPress sites often load files from directories like /wp-content/themes/ or /wp-content/plugins/.
This method works well because most CMS platforms leave behind clear signs in their structure, even if the site owner tries to hide them.
If you want faster results, use tools built specifically for this.
Popular CMS detector tools include:
- CMS Detector
- BuiltWith
- WhatCMS
- Wappalyzer (browser extension)
Just paste the website URL, and the tool will tell you what CMS, and often themes, plugins, and frameworks, the site is using.
These tools scan the website’s code, scripts, and server data to identify patterns that match known CMS platforms. Some tools even give deeper insights, like analytics tools, hosting providers, and marketing technologies used on the site.
This is the easiest and most precise method for beginners, especially if you don’t want to manually dig through code.
4. Inspect URLs and Structure
Sometimes, URLs reveal important clues about the platform behind a website.
Look closely at page links such as:
- /wp-admin → Typically indicates WordPress login/admin panel
- /collections/ → Commonly used in Shopify for product grouping
- /index.php → Often seen in CMS platforms like Joomla or Drupal
- /product/ or /shop/ → Frequently used in eCommerce-focused CMS setups
Also check image and asset paths:
- /wp-content/uploads/ = WordPress media storage
- /sites/default/files/ = Drupal file directory
- /media/ or /static/ = Often used in custom or framework-based builds
These patterns strongly indicate the technology in use because most CMS platforms stick to a consistent file structure. Even when a website is customized, these basic paths often stay the same and can reveal the technology stack.
5. Use Browser Extensions
If you frequently analyze websites, browser extensions are a game-changer.
Try tools like:
- Wappalyzer
- BuiltWith extension
They automatically detect CMS, frameworks, analytics tools, and more right in your browser.
What makes these tools powerful:
- They scan scripts, cookies, and metadata instantly
- Provide detailed breakdowns of technologies used (CMS, hosting, libraries)
- Save time compared to manual inspection
- Often show additional insights like CDN usage, marketing tools, and plugins
With just one click, you can uncover a website’s entire tech stack without manually checking the code. This makes these tools perfect for developers, marketers, and researchers.
This is a slightly advanced method, but still accessible.
Use tools like:
- Chrome DevTools → Network tab
- Online header checkers
Look for clues like:
- X-Powered-By → May reveal the backend technology (e.g., PHP, ASP.NET)
- Server → Can indicate the hosting environment (Apache, Nginx, etc.)
- Set-Cookie → Sometimes includes platform-specific identifiers
- X-Generator → Occasionally shows the CMS name directly
Some CMS platforms leave clear traces, even if the frontend is heavily customized. While this information isn't always visible since many sites hide it for security, HTTP headers can provide quick and reliable confirmation of the technologies employed when they are present.
7. Look for Login Pages
Try visiting common admin URLs:
- /wp-admin → WordPress
- /admin → Various CMS
- /user/login → Drupal
If a login page appears, it can reveal the CMS instantly.
To dig a bit deeper, pay attention to what loads on these pages. The layout, branding, and even small details like form structure or error messages can reveal the platform. For example, a WordPress login page usually has a very recognizable design, while Drupal’s login page often features specific wording and URL patterns.
Also, observe how the page behaves:
- Does it redirect you to a branded login screen?
- Does the URL change (e.g., /wp-login.php)?
- Are there platform-specific logos or hints in the footer?
Even if access is limited, simply reaching the login page can confirm which CMS the site is using.
8. Analyze Website Design & Features
Sometimes, experience helps.
For example:
- Shopify stores often have similar checkout flows
- WordPress sites may use recognizable themes
- Webflow sites have smooth animations and modern layouts
While not 100% reliable, this can give you strong hints.
To refine your observation, look closely at:
- Navigation styles and menu behavior
- Product page layouts and cart interactions
- Animation styles and page transitions
- Footer structures and common elements like “Powered by” text
Many platforms follow design patterns that repeat across thousands of sites. Over time, these patterns become easier to spot. For example, Shopify checkouts are usually very standardized, while Webflow sites often focus on clean, interactive visuals.
Although this method isn’t perfect, combining design clues with other checks can greatly improve your chances of identifying the CMS.
Here are the most widely used CMS platforms you’re likely to detect:
WordPress
- Powers over 40% of websites worldwide, making it the most dominant CMS
- Extremely flexible with thousands of themes and plugins for customization
- Used for everything from blogs to large business websites and eCommerce stores
How to Identify:
- URLs or source code often include wp-content, wp-admin, or wp-includes
- Login pages typically end in /wp-admin or /wp-login.php
- Page source may reference WordPress-specific scripts or meta tags
Because of its popularity, WordPress is a frequent target for security scans and fingerprinting.
Shopify
- One of the most popular platforms for eCommerce websites
- Known for its seamless checkout experience and built-in payment integrations
- Hosted platform, meaning users don’t manage servers directly
How to Identify:
- URLs commonly include /collections/, /products/, or /cart
- Checkout pages often follow a standardized Shopify structure
- Source code may reference cdn.shopify.com assets
Shopify stores typically have a clean, consistent layout that is designed for product browsing and conversions.
Joomla
- Less common today but still used for certain business and community websites
- Offers strong content management features with built-in flexibility
- Often preferred by users who want more structure than WordPress without heavy customization
How to Identify:
- URLs may include /index.php in page paths
- Page source can contain Joomla-specific tags or generator meta names
- Admin login often located at /administrator
Joomla sites may resemble WordPress but often have slightly different URL patterns and backend setups.
Drupal
- Known for powering enterprise-level and government websites
- Highly secure and scalable, but more complex to manage
- Preferred for large, content-heavy platforms with custom requirements
How to Identify:
- File paths often include /sites/default/
- Page source may reference Drupal-specific scripts or settings
- URLs can include ?q= parameters in older versions
Drupal is less visually obvious but leaves identifiable traces in its directory structure and code.
Wix / Webflow
- Drag-and-drop website builders designed for ease of use
- Popular among designers, freelancers, and small businesses
- Hosting, design, and CMS are all integrated into one platform
How to Identify:
- Harder to detect manually compared to other CMS platforms
- Page source may include platform-specific scripts or hosted assets
- Detection tools often identify them through unique fingerprints
These platforms focus on design and simplicity, which can make manual detection tougher without using specialized tools.
Why Some Websites Hide Their CMS
Not all websites want you to know what they’re built on.
They may:
- Remove CMS footprints by deleting meta generator tags, renaming default directories, or removing identifiable code snippets.
- Use custom themes that do not follow standard structures, making it harder to recognize patterns linked to specific CMS platforms.
- Hide identifiers for security reasons to reduce the chances of automated attacks that target known CMS vulnerabilities.
- Change URLs, file paths, or admin access points so they do not match default CMS setups.
- Use security plugins or server-level rules to block detection tools and crawlers
In such situations, even advanced tools might struggle, but combining multiple methods usually yields good results. The goal is to reduce exposure, not to make detection impossible.
Pro Tips for Better Detection
- Use multiple tools for accuracy: Different tools rely on different detection techniques. Some scan code, while others analyze headers or scripts. Combining results increases reliability.
- Combine manual + automated methods: Automated tools are fast, but manual inspection, like checking page source, URLs, or network requests, often reveals hidden clues.
- Don’t rely on just one clue: A single indicator can be misleading. Look for patterns, such as script names, folder structures, or backend endpoints, to confirm your findings.
- Practice on different websites: Try analyzing a variety of sites, including blogs, eCommerce stores, and business pages, to understand how CMS platforms can look different.
- Pay attention to small details: Things like login URLs, asset file names, or even JavaScript variables can quietly reveal the underlying CMS.
- Stay updated with CMS trends: As platforms change, their structures and security practices do too. Keeping up with these changes helps improve your detection accuracy.
The more you practice, the easier it becomes. Over time, you’ll start recognizing patterns almost instantly even on heavily customized or partially hidden websites.
Conclusion
Finding out what CMS a website is using isn’t as complicated as it seems. Whether you’re a beginner, marketer, or developer, you can uncover this information using simple techniques from checking the footer to using effective detection tools.
The key is to mix curiosity with the right tools. Once you get the hang of it, you’ll begin spotting CMS platforms almost immediately.
So the next time you visit a website you admire, don’t just scroll; take a closer look.
