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.
Chromatic publishes 4 APIs on the APIs.io network, including Builds API, Tests and Review API, Projects and Accounts API, and 1 more. Tagged areas include Visual Testing, Visual Regression, Storybook, UI Testing, and Snapshot Testing.
Chromatic’s developer surface includes documentation, engineering blog, and 6 more developer resources.

description: Query builds produced by the Chromatic CLI - the `build(id)` and `project.lastBuild(...)` GraphQL fields expose
build number, status (IN_PROGRESS, PASSED, PENDING, ACCEPTED, DENIED, BROKEN, FAILED), result, browsers, Git commit/branch/slug,
component and story counts, published Storybook URLs, and snapshot capture timings. This is the surface the CLI and Storybook
Visual Tests addon use to initialize and poll visual-testing builds.

description: Inspect and act on individual visual tests. A Test carries its status, result, baseline, and per-browser snapshot
comparisons (TestComparison with base/head captures and pixel diffs). The `reviewTest` mutation accepts, denies, or resets
visual changes, optionally batched across a story, component, or the whole build - the same accept/deny workflow exposed
in the Chromatic UI.

uiTests), branch names, project token, and manage/web URLs; `account(id)` and `viewer` expose account name, subscription
status, and project lists. The `createCLIToken` mutation mints a short-lived CLI token from a project ID for authenticating
build uploads.
