How Can I Tell if a Site Is Using Webflow?

Are you curious if a particular website is built using Webflow? As a web developer or designer, it’s always useful to know the underlying technology behind a site. In this article, we’ll explore some simple yet effective ways to identify if a site is using Webflow.

Inspecting the Source Code

The first step in determining if a site is built with Webflow is to examine the source code. You can do this by right-clicking on any page of the website and selecting “Inspect” (or “Inspect Element”) from the context menu. This will open the browser’s developer tools.

Once the developer tools are open, navigate to the “Elements” or “Inspector” tab. Look for any HTML elements that include class names starting with “w-“, such as <div class="w-container"> or <section class="w-section">. These class names are specific to Webflow and indicate that the site was created using this platform.

Checking for Webflow Assets

In addition to inspecting the HTML structure, another way to identify if a site is using Webflow is by checking for specific assets often associated with this platform. One such asset is the Webflow.js file, which typically appears as:

<script src="" type="text/javascript"></script>

If you find this script tag within the source code, it’s a strong indication that the website was indeed built using Webflow.

Using Third-Party Tools

If manually inspecting source code sounds too complex, don’t worry! Some third-party tools can help you determine if a site is using Webflow.

One popular tool is Simply enter the URL of the website in question, and the tool will provide you with a detailed analysis of the site’s technology stack, including whether it uses Webflow or not.


In conclusion, there are several ways to identify if a site is using Webflow. By inspecting the source code for Webflow-specific class names and assets like Webflow.js, or by using third-party tools like, you can easily determine if a website was built using this powerful website builder.

Knowing the underlying technology used in a website can be valuable for developers and designers looking to gain insights or learn from existing implementations. So next time you stumble upon an awesome website, give these techniques a try to see if it’s powered by Webflow!
