If you're developing an application based on React it can be helpful if you don't need to develop all the basic UI components yourself. Here you can find a list with various components, component libraries and complete design systems developed with and for React.
As the list got longer and longer I thought it would be better to have a "real" site for it.
Choc UI

A component library built on top of Chakra UI components, but where you install by copy-pasting code (like TailwindUI for Tailwind) instead of installing/importing components. Choc = Chakra HOC = Chakra Higher-Order Components.
