Thanks for being interested enough to take a look at the Wiki! Jupiter is the product of over 5 months of active development and over 11 years of work in Web Design.
It is a practical implementation of the ProductiveUI Specification. It provides a decent amount of code support for virtually any web platform.
It provides a Vanilla JS file for handling components in a normal web environment and a library for React projects.
It's easy to learn and easy to use. It looks better by default than most other design systems.
I hope you will find it as useful as I do.
