Storybook vs Chromatic for Component Documentation
Storybook vs Chromatic for documenting and testing design system components. Open source vs hosted, visual testing, and which tool your DS team needs.
Storybook
Free (open source)Teams that need an open-source component explorer with full customization
- Open source component development environment
- Stories for every component state and variant
- Rich addon ecosystem (a11y, viewport, actions)
- Docs mode with MDX for component documentation
- Interaction testing built in
- Framework agnostic (React, Vue, Angular, Svelte, Web Components)
Chromatic
Free tier, $149/moTeams that need automated visual regression testing and hosted component review
- Visual regression testing on every commit
- Hosted Storybook with shareable URLs
- UI Review workflow for design approval
- Built by the Storybook team
- Turbosnap for faster builds
- CI/CD integration (GitHub, GitLab, Bitbucket)
These aren't competitors. Chromatic is built on top of Storybook. You need Storybook regardless. The real question is whether you need Chromatic's visual testing on top. If your design system has more than 20 components and multiple consumers, visual regression testing catches the subtle breaks that unit tests miss. The free tier gives you 5,000 snapshots/month, which is enough for most small teams. Start with Storybook alone, add Chromatic when you start breaking things in production.
