Chromatic
Visual testing and review for UI components
Chromatic is profiled here as a Testing tool for engineering teams. Read about features, pricing, and how it compares to related options in the tools directory.
Description
Chromatic is a visual testing service built by the maintainers of Storybook. On every commit it renders components in cloud browsers, captures snapshots, and flags pixel-level changes for review before they merge, which catches regressions that unit tests never see. Teams also use it to publish Storybooks as living component documentation that designers and PMs can review. The company employs core Storybook maintainers and funds that open-source project, so new Storybook features land in Chromatic quickly. Snapshot allowances on the free plan cover small component libraries, with usage-based plans beyond that.
Key Capabilities:
Visual regression testing with cross-browser cloud snapshots
Storybook, Playwright, and Cypress integration
TurboSnap testing of only the components a commit changed
UI Review workflows with pull request status checks
Interaction tests for component behavior
Accessibility checks alongside visual diffs
