How we detect WordPress plugins

You may have already noticed that we have recently added a new feature to our tool, so that now WPThemeDetector not only detects themes but plugins as well.

This morning I got a tweet from one of our users who was worried about the security of his blog. He twitted it right after checking his own domain in WPThemeDetector and realizing that the plugins he uses were detected and listed. It literally read like this:

@wpthemedetector how do you detect plugins? Do I have a security hole?”

I quickly answered, telling him not to worry at all and suggesting him to read our Frequently Asked Questions, where this is briefly explained. Nevertheless, I decided to write this post to further explain how we do to automatically detect WordPress plugins in a site, what information you´ll get and what you won´t, and the way we deliver that information to you.

First of all, I would like to make clear that our tool will detect only the active plugins used by the analyzed website for which references can be found in the html code genereted and sent by the site´s server.

From the security point of view, that means that if you are checking your own website with our tool, it will do the same harm to your site than any browser would: none at all. So you might or might not have a security hole in your site, but in case you do, we don´t know it and what´s more, we don´t even want to know about it: we will be only reading the html code sent by you (well, I mean, by your server).

Now, from our typical user´s point of view, that also means that we might not be able to detect all the plugins that are used in the analyzed site. Does this disappoint you in any way? I believe it shouldn´t.

I mean, why would you be interested in knowing that the owner of a blog uses, for example, BackupBuddy to back it up? I can think of no reason for it, unless you are part of iThemes. We designed our WordPress Theme Detector to give you valuable information about the WordPress sites you like, not to snoop.

We can look at it this way: If something makes you wonder what plugins are being used in a site and you want to use our tool to find out, that must be something you´ve noticed (somehow you already “detected” it). It could be how well and fast it loads, or some widget you didn´t know about, or how nicely are social media integrated on the site, or any other functionality that caught yor attention. You name it. But one thing is for sure: it wasn´t something hidden and not noticeable, not for instance something that applies only to the backend or admin area of that site.

WPThemeDetector Plugin Detector

So the apparently bad news is that the list of plugins that we are showing you for a particular website does not necessarily include all its active plugins, as we say in the note below the list.

However, the good news is this: If you saw something you liked on that site which is accomplished by a plugin and you want to get more details about it, most surely the html source code is including information about that plugin, because otherwise your browser wouldn´t had let you notice it. And, if that information can be found in the source code, our WordPress plugin detector will find it and you´ll have that plugin listed as part of our results for your query.

Once you have the name of the detected plugins in that list, we offer you two possiblities to access the detailed information about each plugin. As the primary source for further information we are including a button that will take you directly to the plugin page in the WordPress repository, where the vast majority of plugins are submitted and included, or directly to the plugin website. For a small percentage of plugins this won´t work though, so as an alternative we  also offer you a Google search link ready for finding the plugin details for those less usual cases.

Now that you got a little insight into our WordPress plugin detection feature, I hope you like and enjoy our tool better. I´ll be waiting for your comments.


  1. Actually, I think it’s a great tool as I frequently need to know what type of theme I’m dealing with so that I can use the info to develop customized plugins for clients that I am thinking of contacting. Without this information (which I searched diligently and am so glad to have found your app – thanks!) it would be very difficult to come up with an accurate presentation. I love it!

  2. It’s nice idea, show list of plugins in site.

    I think a simple way to search is to search plugins plugins folder in code using regular expressions and extract the folder name with the plugin.

  3. Good tool. I think it will fail to identify Autopilot plugins. Please clarify.

    • What do you mean by “Autopilot plugins”?

      • Plugins like WP-o-matic,WP Robot, etc. Will the tool able to identify?

        • Oh yes, we´ve detected those two plugins you´ve mentioned.

          • I was testing this website labresponsive.net it runs on auto pilot, but the tool failed to detect. Could you please check which plugin the website is being used

          • Sorry NaveenKmar, can´t find any autopilot plugin on that site. Besides, it doesn´t seem to be using automated content. Actually, their current content is pretty old!

  4. Nice tool for checking plugin. 🙂 Thanks Luis.

    • Luis Alejandre will you please tell me name of plugins who protect me to hackers and spam

  5. Wow, But it does not show 100% correct results. I mean this tool did not show all plugins of any website.

  6. Any suggestions on how to hide it ?

    • I’d like to know the answer to that as well!

  7. Nice tool for checking plugin. 🙂 Thanks Luis.

  8. thanks but it doesn’t detect all the plugins

  9. I see several comments about “it fails to detect all plugins”. People, how can it be any more clear? Only those plugins that are active on the page and reveal themselves by being referenced in the page’s source code will be detected. If the page isn’t using the plugin, the tool won’t find it…period.

    I found this page because I was looking through a someone’s source code to find out what they were using for a social media toolbar and figured, “surely, someone’s built a tool for this”. No magic here, guys. Just a tool to save a step and possibly give you a few ideas when you see something new.
