Whether you're researching competitors, seeking inspiration, or evaluating potential web development platforms, identifying if a website is built with Webflow can provide valuable insights. This straightforward guide shows you 2 reliable methods to determine if a site uses Webflow as its website builder.

Why identifying Webflow websites matters

Inspiration gathering: Understand which design elements and interactions are possible in Webflow
Competitive research: See which competitors in your industry are leveraging Webflow's capabilities
Platform evaluation: Assess Webflow sites in the wild before deciding on a platform for your own project
Service opportunities: Identify potential clients who might need Webflow expertise or customizations

1. How to detect Webflow sites using Wappalyzer (automated method)

Wappalyzer is a browser extension that instantly identifies technologies used on websites, including content management systems like Webflow.

Install the extension:
Visit the website you want to analyze
Click the Wappalyzer icon in your browser toolbar
- Look for "Webflow" under the "CMS" or "Page Builder" categories
- If present, the site is confirmed to be built with Webflow

This method takes seconds and requires no technical knowledge.

2. How to detect Webflow sites by checking the source code (manual method)

If you prefer not to install extensions or want to verify Wappalyzer's findings, you can inspect the website's source code:

1. Open the page source:

Right-click anywhere on the webpage
Select "View Page Source"

2. Look for these Webflow identifiers

Search for the Webflow comment:

<!-- This site was created in Webflow. https://webflow.com -->

This comment typically appears near the top of the HTML document in sites built with Webflow.

Check for the meta generator tag:

<meta content="Webflow" name="generator">

This tag explicitly identifies Webflow as the site builder.

Find Webflow-specific data attributes:

data-wf-page="..."
data-wf-site="..."
data-wf-domain="..."

These attributes are automatically added by Webflow to help manage the site.

Look for Webflow JavaScript:

<script src="https://cdn.prod.website-files.com/..."></script>

Webflow sites typically load JavaScript from Webflow's CDN.

If you find any of these markers, the site is built with Webflow. Multiple matches provide stronger confirmation.

Final thoughts

Identifying Webflow-built websites is straightforward using either Wappalyzer for quick detection or manual source code inspection for deeper verification. Both methods are reliable, though the manual approach requires a basic understanding of HTML.
