A theme detector is a tool that can help you find the best theme for your website. It will analyze your site’s current design and show you similar themes available in the market. This will help you find a theme that will fit the needs of your website, especially if you want to make changes to your site’s design.

There are several WordPress theme detectors available on the Internet. They offer similar features with slight differences in interface, content, and capabilities. Below are some of them:

1.   What WP Theme Is That

What WP Theme Is That

What WP Theme is that is a free WordPress theme detector tool that helps you find out what WordPress theme you are using by uploading the header image from a website.

It works with any WordPress theme and shows you the list of themes it thinks you’re using. The only requirement is that you have an active and public header image on your site, which many sites do not. If your site does not have a public header image, you can use the “Get a New Header Image” tool to generate one for your site or use one of their free ones instead.

2. WP Theme Detector

WP Theme Detector

WP Theme Detector is another free plugin that detects WordPress themes by analyzing the source codes of a given website or blog. You can use this tool to check if a specific site is running on a particular theme or not. It works by scanning your website’s home page and recognizing common elements in all WordPress themes such as header, footer, sidebar, etc. 

The plugin also provides information about other plugins installed on your site along with their versions, which helps you identify possible incompatibility issues between them and your chosen theme. In addition to these features, WP Theme Detector also shows you whether your site uses an SSL certificate (which is becoming increasingly important these days).

3. IsItWP


IsItWP is a WordPress plugin that can help you detect whether or not a website is running on a WordPress platform. It’s very useful for developers and businesses who want to know if they’re dealing with a legitimate WordPress site or one that hackers have compromised.

IsItWP can be used to check whether an e-commerce website is running a legitimate version of WordPress or has been hacked and loaded with malicious code. You can also use it to verify if your website is secure or if someone else has already registered the same domain name as you.

The plugin uses the server response headers and other web page elements to determine whether it’s running on WordPress. It runs passively in the background without slowing down your site or interfering with its normal operation.
