How the Page Builder Detector works

From URL to detected builder in 4 steps

    Enter URL

    Enter the address of the page you want to look at. It works for any publicly accessible WordPress site.

  2. 2 Step 2

    Render the page

    We load the page in a real browser, including JavaScript, so that content inserted later is also taken into account.

  3. 3 Step 3

    Count builder elements

    We search the HTML for the typical CSS classes of 10 page builders and count the matching elements.

  4. 4 Step 4

    Read the result

    The report names the main builder, lists further builders and shows theme and plugins alongside.

How to read the result

Four things that help you interpret the detected builder

Main builder
The builder with the most elements on the page is shown as the main result. On a typical Elementor page that is several hundred elements against a handful of Gutenberg blocks.
Several builders
If more than one builder is found, the report lists all of them with their element count. Two full builders on one page are usually a sign of a relaunch that was never finished.
Block theme
The report shows separately whether the theme is a block theme. We check for the file templates/index.html in the theme folder, the reliable marker for Full Site Editing.
Classic Editor
If no builder classes are found, the report shows Classic Editor. That is also the result for pages whose content comes entirely from theme templates or custom code.
WordPress Page Builder Detector: detect the builder of a website

Find out which page builder a WordPress site uses

You like a website and want to know how it was built? Or you are taking over a client project and need to know what to expect before you quote? The InspectWP Page Builder Detector loads the page in a real browser and looks at the finished HTML. Every page builder leaves characteristic CSS classes in its output, for example .elementor-widget for Elementor or .et_pb_section for Divi. We count these elements and tell you which builder the page was built with.

More than the builder: theme, add-ons and plugins in one report

The page builder alone rarely tells the whole story. That is why the report also shows the active theme including a child theme, whether it is a block theme with Full Site Editing, and all plugins detected on the page. This includes typical companions such as Elementor Pro or add-on packs. For agencies this is the quickest way to assess a takeover: you see at a glance whether you are dealing with a lean block setup or with a builder plus a dozen extensions.

Frequently asked questions about the Page Builder Detector

How detection works and what the result tells you

InspectWP opens the URL in a real browser and waits until the page is rendered. Then we search the finished HTML for the CSS classes that each page builder writes into its output. The builder with the most matching elements is reported as the main builder of the page.
