The benefits of a design system are undeniable, if this year you are starting with the creation of your own design system, a little benchmarking will go a long way. In this article, we will look at 8 of the best design systems, their main benefits, peculiarities, and disadvantages.

Giving a bit of context, a design system is a centralized library consisting of a set of general and functional patterns that are interconnected, translated into code, and guided by specific standards, in order to maintain the visual consistency of the digital product and save time.

Founded in 2014, Material Design by Google is one of the most popular design systems today. Staying firm in its strategy, Google has been implementing Material Design in almost all its products in a consistent and effective way, exploring new components for its libraries and providing a very complete documentation of each one of them. Their exemplary use of atomic design has also served as a guide for thousands of UI designers.

Building on the design foundations for the Mac OS X operating system, Apple created design guides to provide a consistent experience across the rest of its products.

The reuse of common elements makes us design faster and have fewer errors, both in interaction and at a visual level, making the final product much more consistent. The use of a design system will also create evolution in the design (product) and the patterns, styles, and usage guidelines - everything supported by the key methodologies that govern good UX and visual design.
