How to check your version

Which Tailwind CSS is this site on?

In the lock file

$ npm ls tailwindcss
└── [email protected]
# package-lock.json is what deploys

In the built CSS

$ head -c 120 public/build/assets/app-*.css
/*! tailwindcss v4.3.3 | MIT License | https://tailwindcss.com */
# the banner names the version that built it

Know before support ends.

Porro reads the PHP, framework and database version from every site and tells you 90 days before support runs out.
