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.

See UI Tests in action

Max coverage, min maintenance

Storybook, Playwright, and Cypress already define tests. Chromatic enhances them with visual, accessibility, and functional checks — no extra test writing required.

Test in real browsers

Chromatic captures snapshots of real code, styling, and assets exactly as users experience them. These snapshots are compared over time to find regressions.

No test flake

Our custom detection algorithm eliminates flakiness from latency, animations, resource loading, and minor DOM structure changes.

Scan all possible UI states to pinpoint regressions

Run three types of tests across four browsers for continuous coverage. Your tests run in parallel by default to deliver results in the least time possible.

Explicit sign-off enforces UI standards

Get designers, PMs, and engineers in one place to share feedback and approve UI. Each decision updates the shared UI context that agents rely on.

Discover UI Review

Stay on top of feedback

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

Every decision in one place

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

Integrates with Git and CI

UI Review status syncs with your version control & CI to keep teams in the loop.

Assign reviewers

Request review from design, product, and engineering in a shared workspace online.

Set default reviewers

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

Connects to your workflows

Keep everyone in the loop with Slack, Figma, and custom webhooks.

“We are using Storybook in every UI layer in all of our organization. Chromatic keeps us safe and helps us ship quality & performant UI.”
