About Storybook

Storybook is an open-source frontend development environment designed for building, testing, documenting, and showcasing UI components and pages independently from the main application. Widely adopted by thousands of development teams, Storybook helps designers and developers create reusable user interfaces faster by providing an isolated workspace where components can be developed, reviewed, and tested without backend dependencies. The platform supports a broad range of frameworks including React, Vue, Angular, Svelte, Web Components, HTML, React Native, Preact, Ember, and others. Storybook includes tools for component documentation, accessibility testing, visual testing, responsive previews, interaction testing, design system development, and collaborative UI reviews. Its extensible addon ecosystem provides integrations for analytics, testing, design assets, GraphQL, accessibility auditing, and more. Built as a monorepo and released under the MIT license, Storybook has become one of the most widely used tools for design systems, component libraries, frontend documentation, and modern UI engineering workflows.
