Flowbite is an ecosystem of open-source libraries, tools, and products built around Tailwind CSS consisting of a Figma design system, component library, website section and page templates, and other tools.
I've been using Flowbite for a few years now, and it's very complete, I always was able to find the components I was looking for, and they're framework agnostic which I appreciate as I make Rails apps.
I use the Svelte Flowbite component library. The components are not as well built as other component libraries but it is still a very solid option. In this case it was my designer who picked it for the aesthetics. I wish the docs were more organised as it is kindof a mess to find anything.
