For me, more important than it being free of cost, is that it is Free and Open Source. I want to support the Tailwind Devs and Tailwind UI is nice and a fair price and all, but I don't want the headache of dealing with licensing. I don't want to have to think about if my license covers a particular new project or use case. I don't want to worry if I open source my project having closed source CSS in it and having to take it out. I don't want to worry about investing time learning Tailwind UI to have them make major licensing changes down the road or get bought out and abandoning it or whatever.

So I can't use Tailwind UI, I can use this.

(If one of my Tailwind-using side projects gets popular enough and starts making me money, I will probably buy a Tailwind UI license just to support Tailwind, though! Even though I won't use it. Or maybe I'll find another way to support them.)

I'm a paying customer of TailwindUI. TailwindUI is more advanced in my opinion:

- There are more components.

- One thing I love are the fully styled landing pages. They are made up of components as well, but I like seeing them put together in a coherent fashion.

- You get not only pure HTML code, but also Vue and React code to copy/paste.

- IMHO it's nicer looking and feels more polished.

However, all of this comes at a price, I think I paid $250 for it. I also find the designs to be nicer, but sometimes they are a pain to change because somewhere in the nested `div`'s there's some magic happening that I'm not dealing with properly.

I do think there is a place for such free, simpler and clean component libraries and I appreciate their creator for making it available.

I have a TailwindUI license but there's no vanilla javascript or alpine support. So the open source options are better on a couple levels!

It is free
