Design systems have arisen from the need of companies to have in hand all those product development processes that go through the complexity of staying up to date with design trends, UX and other series of mobile products.
Creating a design system or pattern library is a must for top companies, apart from being a source of inspiration for those others seeking solutions to their complex problems. Adele from UXPin is an open source repository of design systems and pattern libraries among which you can find Dropbox, Mozilla, GOV.UK or Loney Planet.
Among its characteristics is the ability to get a list of systems that use a particular technology, a data structure or have part of a system that we may be interested in.
Alternative React, CSS in JS (here a link to some CSS from Creativos), color palettes and line guides, everything is in Adele to become an invaluable resource for designers and design teams.
Among its advantages is the possibility of explore technologies used in other company systems, compare data structures, observe the implementation of details in components and obtain material necessary to improve your own design systems.
In total they are 43 systems analyzed in 30 categories and its objective, being an open source tool for the community of design system creators, is to gather more information about all the systems that are publicly available.
An open system for the participation of any designer who wants to help improve Adele's repository. You can approach the web from this link to start exploring the different systems available and thus use them for your own work or for the design team in which you are participating.
