This is the default Hyvä Theme.
We've rebuilt the standard Magento 2 frontend for speed, simplicity, and joy. Now open source and free, Hyvä Theme combines the best of Magento frontend development with modern tools developers love, like AlpineJS and Tailwind CSS.
It's highly-performant out of the box, reduces build times, and powers the next generation of Magento and Adobe Commerce stores built with Hyvä Commerce.
