Overview

Storybook is a frontend workshop that lets developers build and test UI components and pages in isolation, without needing to run the entire application. It captures component states as "stories" that serve as both documentation and test cases, helping teams develop durable interfaces and share UI patterns.

The tool integrates with industry-standard frameworks and tools, making it incrementally adoptable into existing workflows. Storybook supports testing through interaction tests, visual tests, accessibility checks, and snapshot testing—all powered by the stories you write during development. It's open source, free, and used by thousands of teams including Microsoft, Shopify, and others.
