FAQ
How do I check if a website is using Radix UI?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. The popup matches Radix UI's fingerprint signals (response headers, asset URL prefixes, runtime globals, sourcemap paths) and flags it whenever any combination is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Radix UI version can Sourcemap Explorer detect?
Radix UI ships as a hosted ui frameworks rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
Is Radix UI open source?
Yes, Radix UI is open source. The license details are listed on the official site (https://www.radix-ui.com), and the codebase typically lives on a public source-control host.
