How to Tell if a Website Uses Webflow (2026 Guide)

Q: How can I tell if a website uses Webflow?

The fastest way is to scan the URL with Web Reveal—a free tool that detects Webflow and the full tech stack of any website in seconds. Manual signs include a generator meta tag set to 'Webflow', CSS classes prefixed with 'w-', assets hosted on uploads-ssl.webflow.com, and a webflow.io subdomain in the page source.

Q: What is Webflow and how is it different from WordPress?

Webflow is a visual, no-code website builder that generates clean semantic HTML, CSS, and JavaScript without plugins or themes. Unlike WordPress, it is a fully hosted SaaS platform where the layout, styling, and interactions are designed in a visual editor and compiled to production-ready code.

Q: Can a Webflow site hide that it uses Webflow?

Partially. On Webflow's paid plans, sites can remove the generator meta tag and use a custom domain. However, the distinctive CSS class naming conventions (w-, wf-), asset hosting on webflow.com CDN, and Webflow's specific JavaScript bundles are deeply embedded and difficult to fully obscure.

What Is Webflow?

Webflow is a visual web design platform that lets designers build fully responsive, production-ready websites without writing code. Unlike template-based builders such as Wix or Squarespace, Webflow gives designers precise control over layout, interactions, and animations through a visual interface that compiles clean HTML, CSS, and JavaScript.

Webflow hosts sites on its own global CDN and also supports publishing to custom domains. It is particularly popular with design agencies, SaaS marketing teams, and freelancers who want design flexibility without the overhead of a traditional development stack.

Why Detect Webflow?

Identifying that a website is built with Webflow is valuable across many professional contexts:

Webflow agencies and freelancers: Find prospective clients already on Webflow for maintenance, redesign, or migration projects.
Competitive research: Understand whether a competitor's marketing site is built with Webflow and gauge their likely tech budget and team setup.
SaaS sales: Identify companies using Webflow as a signal of a design-forward, growth-stage team that may be receptive to complementary products.
Recruiters: Identify companies using Webflow as a proxy for teams that value design and no-code tooling.
Migration teams: Assess whether a Webflow site is a good candidate for migration to a more flexible headless CMS or custom stack.

Fastest Method: Free Scanner Tool

The quickest and most reliable way to detect Webflow is to use Web Reveal—a free technology scanner that performs live analysis of any URL and returns a full technology stack breakdown, including the website builder, hosting provider, analytics tools, and more. No account required.

Enter the website URL on the Web Reveal homepage. Within seconds, results will confirm whether the site uses Webflow and provide additional context about the full technology stack.

The Web Reveal Chrome extension detects Webflow automatically as you browse, showing the result in the toolbar without needing to leave the page.

Generator Meta Tag

The most straightforward manual signal for Webflow is the generator meta tag in the HTML <head>. Webflow inserts this tag by default on all published sites:

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

To check for it, press Ctrl+U (or Cmd+U on Mac) to view the page source, then search for generator. If the content attribute is "Webflow", the site is built with Webflow.

Note: On Webflow's paid plans, this tag can be removed. If the tag is absent, look for the other signals below.

Webflow CSS Class Patterns

Webflow generates HTML with a distinctive set of CSS class naming conventions. Look in the page source for:

Classes prefixed with w- — Webflow's core utility classes (e.g., w-nav, w-container, w-section, w-row, w-col)
Classes prefixed with wf- — Webflow font and layout classes (e.g., wf-body)
The attribute data-wf-page on the <html> or <body> tag — a unique page identifier Webflow injects into every published page
The attribute data-wf-site — Webflow's site identifier, also injected automatically

Searching the page source for data-wf-page or w-nav is one of the most reliable manual checks, as these patterns are unique to Webflow and cannot easily be removed without post-processing the exported code.

CDN and Asset Hosting

When a Webflow site has not been exported and is hosted on Webflow's infrastructure, all uploaded assets—images, fonts, videos—are served from Webflow's CDN domain:

uploads-ssl.webflow.com — Media and asset uploads
assets-global.website-files.com — An older Webflow CDN domain still used by many sites
global.website-files.com — Another variant of the Webflow asset CDN

Press Ctrl+U to view the page source and search for webflow.com or website-files.com. If either domain appears in image, script, or font URLs, the site is hosted on Webflow.

Webflow Subdomain

Every Webflow site is assigned a permanent subdomain at [site-name].webflow.io. Even when a custom domain is configured, this subdomain remains active and sometimes appears in canonical links, redirects, or sitemap references.

To check, look at the page source for references to .webflow.io. You can also try appending .webflow.io to the company name (e.g., mycompany.webflow.io) to see if Webflow's staging site loads.

JavaScript Globals

Webflow injects a JavaScript configuration object into every published page. Open the browser console (F12 → Console) and check for:

window.Webflow — Webflow's global JavaScript namespace. If this is defined, the page uses Webflow's interactions runtime.
Webflow.push — The Webflow interaction queue function used to register interaction callbacks.

Type window.Webflow in the browser console. If it returns an array or object rather than undefined, the site runs Webflow's runtime.

How Web Reveal Detects Webflow

Web Reveal performs live HTTP analysis of the target URL and checks for multiple Webflow fingerprints simultaneously:

Presence of the generator meta tag set to "Webflow"
HTML attributes data-wf-page and data-wf-site
CSS class patterns such as w-nav, w-container, and wf- prefixed classes
Asset URLs referencing uploads-ssl.webflow.com, website-files.com, or .webflow.io
The window.Webflow JavaScript global in inline scripts

Because Web Reveal checks all of these signals in a single scan, it can confirm Webflow even when the generator tag has been removed or when the site uses a custom domain.

Frequently Asked Questions

How can I tell if a website uses Webflow?

The fastest method is to scan the URL with Web Reveal. Manually, look for <meta name="generator" content="Webflow"> in the page source, or check for data-wf-page attributes and uploads-ssl.webflow.com asset URLs.

What is Webflow and how is it different from WordPress?

Webflow is a visual, no-code website builder that compiles clean HTML, CSS, and JavaScript directly. Unlike WordPress, it requires no plugins, themes, or server-side PHP—everything is designed visually and hosted on Webflow's global CDN. WordPress is an open-source CMS that runs on your own server and is extended through plugins.

Can a Webflow site hide that it uses Webflow?

On paid plans, the generator meta tag can be removed and a custom domain applied. However, Webflow's CSS class patterns (w-, wf-), data-wf-* attributes, and asset CDN domains remain unless the site's HTML is post-processed after export—an uncommon and complex step.

Is Webflow good for SEO?

Yes. Webflow generates clean, semantic HTML with full control over meta tags, Open Graph data, canonical URLs, and structured data. It is widely considered one of the most SEO-friendly no-code builders. Tools like Web Reveal can also reveal which analytics and tracking tools a Webflow site uses.
