Ark UI is a headless component library that provides accessible, unstyled UI primitives for modern web applications. It helps developers build custom interfaces without sacrificing keyboard support, ARIA behavior, or framework flexibility.
Free and open source; no paid plans or per-seat pricing are shown on ark-ui.com, with optional community support and sponsorships.
Open Source
Ark UI is a strong choice for teams building custom design systems without committing to a visual framework. Its headless, accessible primitives save time on keyboard and ARIA behavior while leaving styling fully in your control. The main trade-off is less breadth and fewer polished examples than larger UI libraries. It is best for React, Vue, Solid, or Svelte developers who need reliable unstyled components.
