Storybook homepage showcasing UI development tools

Storybook is an open-source frontend workshop for building, testing, and documenting UI components in isolation. Designed for professional development workflows, it allows teams to develop and preview interface components outside of the main app environment, helping catch edge cases, avoid regressions, and build robust UI systems. Its modular architecture supports a wide range of JavaScript frameworks—including React, Vue, Angular, and more—and integrates with essential tools for testing, accessibility, and documentation.

With over 35 million monthly installs and thousands of contributors, Storybook has become a staple in scalable design systems and component libraries. Features like visual testing, live previews, customizable docs, and integration with testing frameworks (e.g., Chromatic, Jest) make it especially valuable for product teams, design system engineers, and UI developers. It’s free to use, highly extensible via addons, and actively maintained by a large open-source community.
