WordPress powers over 43% of all websites on the internet \u2014 from small blogs to Fortune 500 companies like Sony, Disney, and The New York Times. But not every WordPress site is obvious. Many use custom themes and remove the telltale signs. Our tool digs deeper.

How Does the WordPress Theme Detector Work?
Our WordPress detector analyzes a website’s source code, HTTP headers, CSS files, and JavaScript to identify WordPress-specific patterns. Here’s what it scans for:
Source Code Analysis
Searches for wp-content paths, wp-includes references, generator meta tags, and WordPress-specific HTML classes that confirm a WordPress installation.
Theme Detection
Parses style.css headers for theme name, author, and version. Also checks for popular theme frameworks like GeneratePress, Astra, Divi, and Elementor.
Plugin Fingerprinting
Scans for known plugin CSS/JS files, unique HTML structures, shortcodes, and REST API endpoints that reveal which plugins are installed.
Hosting Identification
Checks server headers, IP ranges, nameservers, and CDN configurations to determine the hosting provider.
Why Use a WordPress Theme Detector?
1. Find Inspiration for Your Own Site
See a beautiful WordPress site and want to know how it was built? Our theme detector tells you exactly which theme and plugins they’re using, so you can recreate similar functionality on your own site.
2. Competitor Research
Analyze your competitors’ tech stack \u2014 what themes they use, which plugins power their features, and where they host. This intelligence helps you make informed decisions about your own WordPress setup.
3. Client Discovery for Agencies
If you’re a WordPress developer or agency, use this tool to identify potential clients. Find sites running outdated themes, missing security plugins, or on slow hosting \u2014 then reach out with a solution.
4. Security Auditing
Check if a site is running an outdated WordPress version or vulnerable plugins. Our detector shows the WordPress version number, helping you assess potential security risks.
Common Signs a Site Uses WordPress
Even without our tool, there are telltale signs that a website runs on WordPress:
| Signature | How to Spot It |
|---|---|
/wp-admin/ |
Add /wp-admin to any domain. If you see a WordPress login page, it’s WP. |
/wp-content/ |
View page source and search for wp-content/uploads \u2014 a dead giveaway. |
| Generator meta tag | <meta name="generator" content="WordPress 6.x"> in the HTML source. |
| WP JSON API | /wp-json/wp/v2/ returns WordPress REST API data if exposed. |
| Login URL | /wp-login.php redirects to the WordPress admin login. |
| Readme file | /readme.html often exists and explicitly says “WordPress.” |
| XML-RPC | /xmlrpc.php is a legacy WordPress API endpoint. |
Pro tip: Many security-conscious site owners hide or disable these signatures. Our detector uses multiple detection methods to identify WordPress even when these are concealed.
How to Hide That Your Site Is WordPress
Want to make it harder for others to detect your site’s tech stack? Here are proven methods to hide your WordPress footprint:
- Remove the generator tag \u2014
remove_action('wp_head', 'wp_generator'); - Hide wp-content paths \u2014 Use a plugin like Perfmatters or WP Hide & Security Enhancer
- Disable REST API for unauthenticated users \u2014 Blocks
/wp-json/access - Block directory listing \u2014 Prevent browsing of
/wp-content/plugins/ - Rename wp-login.php \u2014 Use a security plugin to change the login URL

Frequently Asked Questions
Can this tool detect every WordPress theme?
Our detector identifies 95%+ of WordPress themes, including child themes. However, heavily customized themes, headless WordPress setups, or sites using aggressive security plugins may obscure theme details. If a theme isn’t detected, try our HTTP Headers Analyzer for deeper inspection.
How accurate is the plugin detection?
We detect plugins by scanning for known file paths, CSS/JS handles, shortcodes, and HTML signatures. Most popular plugins (WooCommerce, Elementor, Yoast, etc.) are detected with high accuracy. Less common or custom plugins may not be identified. Detection works best on sites that don’t use aggressive minification or caching that strips plugin signatures.
Is it legal to check what theme/plugins a site uses?
Yes. Our tool only analyzes publicly available information \u2014 the same HTML, CSS, and JavaScript that any browser downloads when visiting a site. We don’t access any private areas or bypass security measures. This is standard competitive research that agencies and developers do every day.
Why would someone want to hide their WordPress theme?
Some site owners hide their theme and plugin details for competitive reasons (preventing copycats) or security (avoiding targeted attacks on known vulnerabilities in specific themes/plugins). While our detector can identify many hidden WordPress installations, we respect site owners’ choices to obfuscate their tech stack.
What’s the difference between WordPress.com and WordPress.org?
WordPress.org is the free, self-hosted version where you install WordPress on your own hosting. WordPress.com is a managed hosting service by Automattic. Our detector can identify both, but plugin detection is more limited on WordPress.com sites due to their restrictions.
Can I use this tool to audit my own WordPress site?
Absolutely! Enter your own URL to see what information your site reveals to the public. This is an excellent security practice \u2014 you might be surprised how much your site exposes. After checking, use our HTTP Headers Analyzer to check your security headers and Speed Test Tool to measure performance.
