Prime is not the next UI Kit. It is a Design System Kit, you may also think of it as of Design Starter Kit.
What's more it is probably the smartest Figma Kit on the market - it includes all newest Figma features. Best practices from real design systems and tricks for professional users.
Prime loads fast. It includes only needed components. The kit ensures the right architecture & exposure of the components - this means you will pick elements with ease.
Use it when you want to design for Web, Desktop, Mobile 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.
