Clarity Design System vs GitHub Primer

Clarity Design System is a free, open-source toolkit for enterprise-focused interface design, with inclusion at its center. It combines design assets—including Figma themes, icons, color libraries, fonts and downloadable SVG icons—with more than 30 components and over 200 icons. Clarity Core provides reusable Web Components for Angular, React, Vue, other JavaScript frameworks, or projects without a framework. It is compatible with Webpack, RollupJS, Parcel and most framework CLIs. React projects need the additional @cds/react wrapper because React does not fully interoperate with custom elements. The datagrid supports more than a dozen features and thousands of data entries. Clarity follows WCAG 2.1 AA guidelines and has a dedicated accessibility team; accessibility checks cover multiple tools, screen readers and browser combinations. The code is licensed under MIT. Community questions go through GitHub Discussions, while issues and feature requests are tracked in GitHub Issues. Each major release is actively supported for six months after the next major release becomes available. Clarity Core currently requires a JavaScript bundler to import its dependencies.

GitHub Primer is a free, open-source design system for designing and building GitHub interfaces. Its guidance covers product UI components, patterns, and design tokens for color, spacing, and typography. Primer Brand addresses marketing websites and other digital experiences. React documentation explains theming, recommended practices, and component extension. Primer also provides accessibility guidance and tools, along with Octicons, GitHub’s scalable icon set. Product UI documentation includes an MCP server page. Component status is identified as experimental, ready, or deprecated; ready components are described as mature with long-term support expected. Primer Web and Primer Primitives are available through the Primer Figma Community page, while GitHub’s Figma organization is limited to GitHub team members. The Primer Mobile Figma library is internal only. GitHub employees alone can contribute to Primer Web because of Figma’s open-source file handling. GitHub’s Design Infrastructure and Design Engineering teams maintain the CSS framework, documentation, tools, libraries, and component libraries.
