Chromatic
Visual testing & review tool for web UIs that catches bugs before they reach users
About Chromatic
Chromatic is a visual testing and review platform built by the Storybook team that automates UI quality assurance. It scans every possible UI state across multiple browsers to detect visual, functional, and accessibility bugs. The platform integrates with existing test frameworks like Storybook, Playwright, and Cypress to enhance them with visual regression detection, accessibility compliance checks, and interaction testing—without requiring additional test writing. Teams can assign reviewers, post feedback directly on components, and streamline sign-off processes through a centralized UI review interface.
