How to Detect a Webflow Website: 7 Reliable Methods

Curious about a sleek, high-performing website? There's a good chance it's powered by Webflow. Knowing a site's underlying technology, especially if it's Webflow, offers founders, developers, and marketers a competitive edge, revealing insights into design agility, development speed, and potential strategic opportunities.

Webflow has revolutionized web design and development by offering a powerful visual canvas paired with robust CMS capabilities, all without writing a single line of code (unless you want to). Its speed, responsiveness, and design flexibility make it a top choice for startups, agencies, and enterprises alike. But how do you confirm your suspicions and definitively identify a Webflow site? Let's dive into seven reliable methods.

1. Inspecting the HTML Source Code

One of the most definitive ways to identify a Webflow site is by examining its HTML source code. Webflow leaves distinct fingerprints in the generated markup, which are often easy to spot.

To do this, simply right-click anywhere on the webpage and select "View Page Source" (or "Show Page Source" depending on your browser).

What to look for:

* Generator Meta Tag: Webflow frequently adds a generator meta tag in the section of the HTML. While not always present (it can be manually removed), its presence is a dead giveaway.

* Webflow-Specific Data Attributes: Look for custom data attributes prefixed with data-wf-. These are core to how Webflow functions.

* data-wf-page: Identifies the specific page in Webflow.

* data-wf-site: Identifies the overall Webflow project.

* Characteristic CSS Classes and IDs: Webflow generates a lot of boilerplate CSS classes, often with w- prefixes or specific naming conventions. While some can be customized, many remain consistent.

* w-container, w-row, w-col: Common Flexbox/Grid layout classes.

* w-slider, w-nav, w-tab: For specific components.

* w-node-[random_string]: Unique IDs for elements, especially those controlled by interactions or CMS. These are highly indicative.

By sifting through the source code for these patterns, you can quickly confirm a Webflow build. It's a reliable method because these elements are fundamental to how Webflow structures and executes its designs.

2. Utilizing Browser Developer Tools (Elements & Network Panels)

Browser developer tools are powerful utilities for front-end analysis. They offer a dynamic view of the page's structure and network activity, making Webflow detection straightforward.

To open developer tools, right-click on the page and select "Inspect" (or press F12 on Windows/Linux, Cmd + Option + I on macOS).

What to look for in the Elements Panel:

* The "Made in Webflow" Badge Element: Even if the badge isn't visually present, its HTML element might still exist in the DOM, simply hidden via CSS. Search the Elements panel (Ctrl+F or Cmd+F) for

* Webflow-Specific Classes and Attributes (Dynamic View): The Elements panel allows you to dynamically inspect any element on the page. Hover over or click on various sections and observe the classes and attributes. You'll often find w- prefixed classes (w-container, w-slider, w-button) or data-wf- attributes quickly.

* Inline Styles and Interaction Attributes: Webflow generates specific inline styles for its animations and interactions. Look for data-w-id attributes or style tags with transform properties that indicate Webflow's interaction engine at work.

What to look for in the Network Panel:

* Requests to cdn.webflow.com: Webflow hosts many of its core JavaScript and CSS files, as well as images, on its Content Delivery Network (CDN). In the Network tab, filter requests by "JS" or "CSS" and look for URLs starting with https://uploads-ssl.webflow.com/ or https://assets.website-files.com/ (older Webflow domains). This is an extremely strong indicator.

* Typical files: webflow.js, webflow.css, [your-project-id].webflow.css, [your-project-id].webflow.js.

    https://assets.website-files.com/[SITE_ID]/css/[PROJECT_NAME].webflow.css
    https://assets.website-files.com/[SITE_ID]/js/webflow.js

This method provides real-time insights into the resources a site loads and how its elements are structured, leaving little doubt about a Webflow presence.

3. The "Made in Webflow" Badge (Visual Check)

The most straightforward and often immediately visible indicator is the "Made in Webflow" badge. By default, all sites published on a free Webflow plan display this small, floating badge.

What to look for:

* Location: The badge typically appears in the bottom-right corner of the browser window. It's a small, subtle rectangle with the Webflow logo and text.

* Clickability: Clicking on the badge will usually lead directly to Webflow's homepage (webflow.com).

Important Considerations:

* Paid Plans Remove It: Clients on paid Webflow plans (Site Plans or Workspace Plans) have the option to remove this badge. Therefore, its absence *does not* mean the site isn't Webflow. Many professional Webflow sites choose to remove it for a cleaner, branded experience.

* Custom Code Removal: Savvy developers can sometimes hide or remove the badge using custom CSS or JavaScript even on free plans, although this is less common due to Webflow's terms of service for free hosting.

While highly visible when present, rely on this method with caution. If it's there, it's Webflow. If it's not, you'll need to use the other methods.

4. Utilizing Online Website Technology Detectors

For a quick, automated assessment, online tools are invaluable. These services scan a website and report the technologies they detect, often including CMS platforms, frameworks, and analytics tools.

Recommended Tools:

* BuiltWith: One of the most comprehensive tools. Enter a URL, and BuiltWith will provide an extensive list of technologies, often explicitly stating "Webflow" under "CMS" or "Website Builders."

* Wappalyzer: Available as a browser extension (Chrome, Firefox, Edge) or an online tool. Wappalyzer is excellent for immediate, on-the-fly detection. Simply navigate to the site, click the Wappalyzer icon, and it will list detected technologies, including Webflow if present.

* AIWebsiteDetector.com: As your go-to AI-powered detection tool, AIWebsiteDetector.com offers a highly accurate and efficient way to identify Webflow sites. Our advanced AI algorithms analyze multiple data points – including HTML structure, asset paths, script signatures, and server responses – to provide precise detection results. Just paste the URL, and our system will quickly tell you if it's Webflow, along with other critical tech stack information. We excel at identifying Webflow even when standard indicators (like the badge) are removed or obfuscated.

These tools automate the detection process, making them efficient for initial discovery, especially for marketers and founders who may not want to dive into source code.

5. Analyzing CSS/JS File Paths and Domains

This method builds on the network inspection but focuses more specifically on the URL patterns and domains from which core assets are loaded. Webflow has a very consistent pattern for its hosted resources.

What to look for:

* Direct cdn.webflow.com or assets.website-files.com references: As mentioned, the presence of cdn.webflow.com or assets.website-files.com in the URLs of .js or .css files is a near-absolute confirmation.

* Example: https://assets.website-files.com/[SITE_ID]/css/style.webflow.css

* Example: https://uploads-ssl.webflow.com/[SITE_ID]/[ASSET_PATH]

* Specific File Naming Conventions: Webflow often generates CSS files named [project-name].webflow.css and JavaScript files like webflow.js. Even if these files are downloaded and served from a different CDN or domain (which is rare but possible with complex setups), their content or comments might reveal their Webflow origin.
