Carrot Seed Design System

I would call this the perfect intermediate level Design System template. It's a beautifully structured Design System that you can either use to develop your own software systems or mobile apps, or you can use this template's structure to create your own Design System.

The reason the Carrot Seed Design System is so good is that it's just laid out in a really clean and understandable way, fitting in hundreds of components and elements in an easy to understand way.

Also why is it an intermediate design system? Well it's much too detailed to be a simple design system but doesn't contain the full list of possible components for it to be classed as advanced.  It also doesn't include design tokens which is the new way of applying a naming convention to design systems so that they're easy for developers to code with.
