Found the perfect website to use as inspiration on how to customize your WordPress site? A WordPress theme detector can help identify the theme or plugin behind any site's design.
Use it to gain ideas and customize your own site, but first, make sure the website was created with WordPress.
How to Tell if a Site was Made with WordPress
There are three primary ways to tell if a site is using the popular Content Management System (CMS) like HubSpot's Content Hub:
1. Check the footer.
Sometimes, you can find this information in the footer. If you don't see any mention of WordPress there, open the source code of the page (CTRL + U) and search the text (CTRL + F) for "wp-content".
You can find instances of "wp-content" in the source code that confirms this fact.
2. Manual theme and plugin detection.
You can look at the source code of a page (remember, CTRL + U) and find out yourself.
Each WordPress theme needs two files to work: index.php and style.css. The style.css file will show you the name of the theme.
Search for "wp-content/plugins" to discover the plugins used on a WordPress site. You can do a quick Google search with the title you’ve found and find the link to it from there.
3. Using a WordPress theme detector.
A WordPress theme detector is a free extension or website where you can input any URL to identify the WordPress theme present on the page.
If you’re wondering where to find the detector tool you need, here’s a list of our favorite detectors below.
