Chromatic

About Chromatic

Chromatic is a comprehensive visual testing and UI review platform explicitly designed by the core maintainers of Storybook. It automates the process of gathering UI feedback and catching visual regressions across modern web applications. By seamlessly integrating into your continuous integration (CI) pipeline, Chromatic ensures that every component and page is pixel-perfect before it merges into production.

The platform excels at accelerating the UI development lifecycle by capturing snapshots of your user interfaces in the cloud. It then compares these snapshots against known baselines to highlight exact visual differences. Teams can effortlessly review UI changes, leave comments, and approve pull requests within a dedicated workspace, bridging the gap between engineering, design, and product management.

Beyond basic image comparison, Chromatic leverages proprietary features like TurboSnap, which intelligently tracks file changes to determine precisely which tests are affected. This drastically reduces test execution time and prevents compounding costs by reusing unaffected snapshots, making it highly scalable for enterprise environments.

Key Features

• Visual Tests: Automatically captures and compares snapshots of your UI components across Chrome, Firefox, Safari, and Edge to catch visual regressions.
• TurboSnap: Intelligently tracks Git file changes to run tests only on affected components, reducing snapshot usage and saving time.
• UI Review: Provides a collaborative workspace for teams to discuss, review, and approve UI changes alongside code reviews.
• Interaction Tests: Simulates user behaviors like clicks and inputs to verify that complex component states render correctly.
• Accessibility Tests: Integrated a11y reporting to help teams catch accessibility violations simultaneously with visual tests.
• Figma Plugin: Connects your code implementation directly with design specs by embedding Figma designs next to Storybook stories.
