Design systems software is a tool that helps designers and developers create, manage, and maintain consistent and cohesive design systems. It provides a centralized platform where design assets, components, guidelines, and documentation can be stored, shared, and accessed by the entire team. Design systems software enables users to define and enforce design standards, such as color palettes, typography, spacing, and layout rules. It allows for the creation of reusable design components and templates, ensuring consistency and efficiency in the design process.
