3. 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:

1. Right-click anywhere on the webpage
2. 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.

By recognizing Webflow sites, you can gather inspiration, conduct competitive research, and make more informed decisions about your own web development projects.
