I'd like to point out a few things. 1. Tailwind UI is built on top of Tailwind CSS, Tailwind CSS is not closed source. Tailwind UI does ship with a plugin to Tailwind CSS that adds a bit of extra customizations on top, but not much, and even still that is open source. B. Tailwind UI is a collection of components built on top of Tailwind CSS, the beauty of Tailwind CSS is that it's easily customizable, sure you can copy and paste these components into your app, but they are sooo easily customized that you just change `bg-blue-700` with whatever color you want your app to be and boom, it's different. Without the headaches of most other UI frameworks like Bootstrap. III: I maintain Awesome Tailwind CSS project (https://git.io/awesome-tailwindcss https://git.io/awesome-tailwindcss) and we have a section for sites & apps built in Tailwind. I review all sites to make sure they are indeed built in Tailwind, and honestly, I have to view source and read CSS class names to make sure they are Tailwind because it's not easy to tell from the look of the site.
