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.
