In their own words
Carbon Design System
Carbon Design System is IBM’s open-source design system for digital products, shaped by the IBM Design Language. Carbon Core provides foundations, components, patterns, code, and guidance for teams building consistent digital experiences. Carbon for Products adds product-oriented components, styling, and guidance, with components built using React. The wider ecosystem includes Carbon for AI guidelines and reusable elements, Carbon Charts, and integrations such as Carbon for Cloud, Carbon for AEM, and Carbon React Native. Design kits maintained in Figma receive library updates automatically. Carbon MCP lets AI applications or agents query colors, typography, component details, and usage guidance. Web components are available as ES modules or through a CDN and can be used with frameworks such as Angular or Ember. Developer resources include GitHub repositories, Storybooks, tutorials, Carbon Devtools, a color-contrast checker, and UI Builder. The builder can export presentation images, demo apps, or frontend code. Components follow accessibility checks based on IBM’s checklist. Carbon is free to use and contribute to, with no paid tiers stated. Its patterns cannot include code for every possible implementation.

The free Core plan costs nothing and uses an MIT license for personal and commercial use.
