Built with Tailwind CSS

Built with Tailwind CSS tells you whether the site you’re on uses Tailwind CSS—and when possible, which version—without leaving the page. It’s for developers, designers, and anyone curious how a site is styled.

Open the popup to see a clear yes/no style result, the current site’s hostname, and a refresh if you want to scan again. A small badge on the extension icon can show a short version hint when Tailwind is found (Chrome only fits a few characters there). You can switch light or dark theme for the popup.

Everything runs in your browser: it inspects stylesheets and related page content to detect Tailwind-style signals. Results are cached per domain on your device so repeat visits stay snappy; cache can reset on a long schedule. No accounts, no tracking, and nothing is sent to us—this is an open-source tool you can review on GitHub: https://github.com/dankore/built-with-tailwind-css

If you work with Tailwind or compare sites often, install it to get an instant read on Tailwind usage while you browse.
