How to Tell if a Website Uses Radix UI

Identifying whether a website was built with Radix UI used to require technical expertise — inspecting source code, tracing network requests in DevTools, and knowing which patterns to look for. Our free scanner automates all of that: it fetches the page, analyzes 2 Radix UI-specific signals, and returns a verdict with a confidence score.

You might want to detect Radix UI for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.

How to Manually Detect Radix UI Websites

Method 1 — View Page Source

  1. Open the website in your browser
  2. Press Ctrl+U (Windows) or Cmd+Option+U (Mac)
  3. Search (Ctrl+F) for radix-ui or radixui
  4. If found in script src, class names, or meta tags — it's likely Radix UI

Method 2 — Browser DevTools Network Tab

  1. Press F12 to open DevTools
  2. Click the Network tab and reload the page
  3. Filter by radix in the search box
  4. If you see requests to Radix UI-specific domains, it's confirmed
Faster: Skip the manual steps — paste the URL into our scanner above and we check all 2 signals in seconds.

How Our Radix UI Detector Works

When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 2 Radix UI-specific fingerprints:

Script analysis

We scan all loaded JavaScript files for known CDN paths and runtime names

CDN domain matching

We cross-reference every asset request against known platform CDNs

HTML pattern scanning

We search the DOM for platform-specific class names and data attributes

Header inspection

We read HTTP response headers that identify the server or platform

Meta tag extraction

We check generator and other meta tags in the document head

Confidence scoring

We weight each matched signal and normalize to a 0–99% score

Frequently Asked Questions

How can I tell if a website was built with Radix UI?

The most reliable ways to detect Radix UI are: (1) open DevTools → Network tab and look for requests to Radix UI-specific CDN domains, (2) view page source and search for Radix UI-specific class names or data attributes, (3) use our free scanner — we check 2 detection signals automatically and return a confidence score.

Is your Radix UI detector free?

Yes, completely free. Paste any URL into our scanner and we'll analyze it for Radix UI fingerprints immediately. No account required, no limits on scans.

How accurate is the Radix UI detection?

We check 2 unique Radix UI fingerprint signals across HTML, JavaScript, CDN domains, meta tags, and HTTP headers. Our confidence score reflects how many signals matched — a score above 70% is a strong indicator. We cap accuracy at 99% to reflect that all fingerprint-based detection is probabilistic.

Can Radix UI sites be detected if they use a custom domain?

Yes. Custom domains don't hide the underlying platform. The JavaScript files, CDN requests, HTML attributes, and server headers all remain identifiable regardless of the domain name used. Our scanner fetches the page directly and analyzes its technical composition.
