The best WordPress theme detectors

The best WordPress theme detectors

As UX designers and content creators, our favorite WordPress themes are revealing. A preference for a streamlined, uniform theme might reflect a love of organization. Bright themes with large photos and bold navigation could connect with the inner child. 

Some themes, like Astra and Divi, can be recognized almost immediately due to their popularity. But other themes can be like hidden gems, even to experienced WordPress users. No matter what your preference in WordPress themes might be, many of us can relate to that moment when you visit a site for the first time and think, “Wow! What WordPress theme is that?”

With a little detective work, a knowledgeable WordPress pro can almost always inspect the site and come up with the name of the theme that was used. However, the quickest way to find out is by using a WordPress theme detector. 

What is a WordPress theme detector? 

Much like a color picker or image search engine, a WordPress theme detector scans any website to figure out what WordPress theme a site uses. The best tools can also help you discover other important details, such as theme version, author, and child themes or plugins that are present. 

How do WordPress theme detectors work?

There are several ways that WordPress theme detectors can identify the theme that a website is using. One common method is to scan the website’s source code for specific theme-related files or code snippets.

What are WordPress code snippets?

WordPress code snippets are small pieces of code that can be added to your WordPress website to add new functionality or modify existing features. These snippets are typically written in PHP and can be added to your website using a variety of methods, including the functions.php file, custom plugins, or specialized snippet plugins.

For example, a WordPress theme might have a unique stylesheet or JavaScript file that is only used by that theme. A theme detector can find these files and use them to identify the theme.

Another way that theme detectors work is by using a database of known WordPress themes. These databases are constantly updated with new themes, and they allow the detector to match the website’s code with a known theme. Some theme detectors even use machine learning algorithms to improve their accuracy and identify new themes that haven’t been added to the database yet.

Remember that swapping WordPress themes should be carefully considered, even if you absolutely love what you see on another site. A WordPress theme detector won’t provide certain key knowledge, such as whether the theme has been customized or whether it is a good choice for SEO. 

Here are four of the most accurate and free, WordPress theme detectors.
