What is the difference between UI Kit and design system?

A UI kit (User Interface kit) is a set of design elements, such as icons, typography, colors, shapes, and more, used in creating the user interface of a website or application. UI kits serve as a unified and consistent design element, allowing for the quick and efficient creation of new pages and elements without having to create them from scratch. A design system is a broader term that encompasses UI kits and other design elements, such as source files, styles, and templates, used in creating a digital product. A design system provides a unified and consistent foundation for design creation and maintains overall continuity between the individual elements in the product.
