Storybook provides a sandbox to build UIs in isolation so you can develop hard-to-reach states and edge cases.
Build UIs in isolation
Implement components and pages without needing to fuss with data, APIs, or business logic.
Mock hard to reach use cases
Render components in key states that are tricky to reproduce in an app.
Document use cases as stories
Supercharge your workflow with addons
Use addons to customize your workflow, automate testing, and integrate with your favorite tools.
“Storybook is a powerful frontend workshop environment tool that allows teams to design, build, and organize UI components (and even full screens!) without getting tripped up over business logic and plumbing.”

Test UIs with less effort and no flake
Stories are a pragmatic, reproducible way to keep track of UI edge cases. Write stories once then reuse them to power automated tests.
Spot test in a glance
Whenever you write a story you get a handy test case. Quickly browse stories to make sure your UI looks right.
Visual test appearance
Pinpoint UI changes down to the pixel by comparing image snapshots of stories.
Unit test functionality
Reuse stories in your unit tests to confirm nuanced functionality.
Check stories for WCAG and ARIA issues with the A11y addon.
“The tool we use for editing UI is Storybook. It is the perfect place to make sure your work aligns with designs to the pixel across breakpoints.”
Document UI to share with your team
Stories show how UIs actually work not just how they're supposed to work. That makes gathering feedback and reproductions easy.
Find any component or page in your app
Storybook is a searchable, single source of truth for your UI.
Get timely feedback during development
Publish Storybook online to give your team a universal reference point for feedback.
Share components across screens and apps
Every story is a use case that your team can find and reuse.
Generate UI docs automatically
Write Markdown/MDX to generate a customizable site for component libraries and design systems with our Docs addon.
“Storybook has made developing components more streamlined by allowing us to easily include technical documentation within our design system!”
