Composal vs Chromatic

Chromatic derives coverage from Storybook stories and reviews whether component rendering changed.

Two workflows, side by side

Composal

Composal sends AI browser agents to use your running web app and check the outcomes you care about. Define journeys as plain-English Scenarios, map existing flows with Discovery, or explore for bugs with Deep Scan. Runs keep recordings and reproduction steps so your team or coding agent can investigate a Finding.

Chromatic

Storybook visual testing and UI review

Chromatic turns Storybook stories into visual tests, rendering component states in cloud browsers and comparing snapshots with accepted baselines.

Where each fits

Choose Chromatic when Storybook is central to your design-system workflow and you want visual and UI checks tied to stories and pull requests.

Try this evaluation

Select a shared component with several Storybook states and one user journey that combines it with navigation and form behavior. Introduce a subtle visual change in one story and a separate interaction regression in the full application.

Coverage: Which user outcomes must this release prove, and which specialist checks must stay in your existing stack?
Setup: Who prepares accounts, test data, permissions and access to the deployment being tested?
Evidence: Can the engineer reproduce a reported failure from the recording and steps, without asking the tester to investigate again?
Ownership: Who updates the checks when the product changes, and can the team review what a passing result actually proves?
