Chromatic is a cloud visual testing and UI review platform built by the maintainers of Storybook. It captures snapshots of components and pages across cloud browsers, then compares each new snapshot to a stored baseline to catch visual regressions in appearance, layout, fonts, and color. Chromatic runs visual tests, interaction tests, and accessibility (axe) tests against Storybook, Playwright, and Cypress, with UI Review, TurboSnap change detection, and Git/CI integration. Its primary developer surface is the Chromatic CLI, which uploads builds and drives testing over a documented public GraphQL API at index.chromatic.com used by the CLI and the Storybook Visual Tests addon.
