Prime is not the next UI Kit. It is a Design Starter Kit. Prime is the set of 7 UI Libraries that helps you create better designs faster.
Use it when you want to design for Mobile, Web or you would like to create an entire Design System. Never start your work from scratch again!
The kit lets you design quickly with world-class standards out-of-the-box. The ideal word for Prime is “UI Design Starter Kit” because it lets you start to design your next project within a couple of minutes, not hours.
