Storybook

Storybook is a development tool for building UI components in isolation, separate from the application they belong to. Each component gets a story that renders it in different states and variations, making it possible to develop, review, and test components without navigating through the full application to reach them.

The tool supports React, Vue, Angular, Svelte, and Web Components with an addon ecosystem for visual regression testing, accessibility auditing, responsive viewport simulation, and interaction testing. It generates component documentation automatically from code and stories, creating a living style guide that stays in sync with the codebase. For teams practicing component-driven development, Storybook accelerates the workflow by letting developers build and polish components before integration. It also improves collaboration by giving designers and product managers a browsable catalog of available components with supported props and visual states.
