Tailwind Detector

Automatically detects if a website uses Tailwind CSS, shows the version, and lights up the icon in real time.

Instantly identify whether any website uses Tailwind CSS and which version is running as you browse. FEATURES • Real-time toolbar indicator: the extension icon lights up automatically and displays the detected version right on the badge (for example, v4.0 or v3.4) without clicking. • Exact and major version detection: shows the exact compiler version number when present in the page stylesheets, or the major branch (v4 or v3). • Support for Tailwind CSS v3 and v4: recognizes both classic stylesheets and modern Tailwind CSS setups. • Inspector HUD with Light and Dark themes: a compact, high-contrast popup that follows your operating system preference or manual toggle. • One-click re-analysis: re-check dynamic single-page applications anytime directly from the popup. HOW TO USE 1. Install the extension and pin it to your browser toolbar. 2. Browse any website: when Tailwind CSS is detected, the icon lights up with the detected version badge. 3. Click the icon to view the full version tag, active domain, re-analyze button, and theme switcher. PRIVACY This extension does not collect, store, or transmit any personal data or browsing history. All detection runs 100% locally on your device using only the minimum required permissions.
