Kumo is Cloudflare's open-source React component library providing accessible, design-system-compliant UI components built on Base UI. It ships as an npm package with a companion CLI for querying component docs, a Figma plugin for design token sync, and a live documentation site.

Use cases

• build accessible react ui components
• react component library with keyboard navigation and aria support
• design system components for web apps
• add dialogs, dropdowns, tables and toasts to a react app
• query component documentation from the cli
• sync design tokens between figma and code
• charts and data visualization components for dashboards

When to choose

• you are building a React web application and want pre-built accessible components
• you want a design-system-consistent look without hand-rolling ARIA and focus management
• you need tree-shakeable granular imports and Base UI primitives
• you work in the Cloudflare dashboard ecosystem or want its design language

When to avoid

• your project is not React-based
• you need fully custom visual design rather than a design system
• you want a headless-only solution without styling opinions
• you need Vue, Svelte, or Angular components
