UI Testing for devs & agents

Every change, whether by a developer or an agent, gets tested in real browsers. Snapshots cover all UI states, themes, and viewports to detect regressions fast.

Visual

Find bugs in appearance, layout, fonts, and colors

Accessibility

Detect WCAG violations and compliance issues

Interaction

Verify click, type, hover, and drag interactions

“Chromatic is a valuable addition to our testing toolset. It helps us catch UI bugs a lot quicker and easier!”

Sr. Software engineer

Explicit sign-off enforces UI standards

Bring designers, PMs, and engineers together to share feedback and approve UI. Each decision updates the shared UI context that agents rely on.

Stay on top of feedback

Get notified of changes and discussion via email and pull request checks.

Keep track of every decision

Post comments and change requests right beside your live components, so that everyone can follow decision-making.

Syncs with Git and CI

UI Review status shows up in pull requests and CI so sign-off stays visible alongside your code changes.

Assign reviewers

Bring design, product, and engineering together to review UI changes.

Set default reviewers

Automatically assign specific stakeholders to review open pull requests to speed up sign-off.

UI context powers your entire team

All your components, stories, tests, and docs live in one shareable workspace. This defines the UI context your teammates and agents depend on.

Catalog all your components

Explore UI components from across your company without touching a repository.

Self-updating

Every code push auto-updates your component library and the UI context your agents use.

Searchable component libraries

Find out how and where UI components are used in your projects.

Component API, docs, and examples

Reference component metadata to build faster with fewer errors. When you connect an agent, this metadata is transformed for machine readability.

Coming Q1 2026

Invite teammates and agents

Invite stakeholders to reference your UI library. Connect agents via MCP to reuse validated components in UI generation.

History down to the commit

Compare components across branches & commits to review past versions.

“The more things we have in Storybook, the more coverage we get in Chromatic.”
