10 Best WordPress Plugin & Theme Checkers (2024)

Do you agree that there are times when we’re curious about the themes and plugins used by a particular WordPress website? However, website owners often prefer not to openly share this information, which is understandable. So, how can we find the answer to this question? Fortunately, we live in a modern technological world where platforms provide us with the capability to obtain detailed information about the themes and plugins a company utilizes for its website. Thus, we don’t need deep programming knowledge to apply the functional features someone else uses on their WordPress website.

How to Determine if a Website Was Created Using WordPress?

So, how to identify if a website is built with WordPress? This popular platform powers millions of sites, but identifying one can be tricky. But don’t worry; there are detective methods to unveil the secrets behind a website’s creation. Let’s explore some ways to sniff out if WordPress is the mastermind behind the scenes!

Try adding “/wp-admin” to the website’s URL. If it leads to a login page (though it might be disguised for security reasons), it strongly indicates that WordPress was used to power that website.

Method 2: Looking at the code

Right-click and view the page source. Search for keywords like “WordPress” or “wp-content” in the code. These suggest the site uses WordPress.

Method 3: Online tools

Several online services can identify website technologies. Search for “WordPress website detection tools” to find these. They analyze the website’s code and provide details about its platform and potentially used plugins.

What are WordPress plugin and theme checkers?

WordPress plugin and theme checkers are web-based tools that analyze a website to identify the specific theme and plugins powering it. This information can be valuable for developers, designers, and marketers alike.

Will using the same theme and plugins as a successful website guarantee my website’s success?

Are there any privacy concerns when using a theme and plugin checker?

Generally, checkers analyze publicly available website data. However, it’s important to be respectful of website owners’ privacy. Don’t use checkers for malicious purposes like copying someone’s entire website content.


Discovering the right plugins and themes is essential for a successful WordPress website. By utilizing top plugin and theme checkers, you can ensure compatibility, security, and functionality, ultimately enhancing your site’s performance and user experience.
