Automatic UI Tests that catch bugs instantly

Run visual and interaction tests across browsers, themes, and viewports at the same time. Maximum coverage. Zero extra effort.

Test in a real browser
Chromatic takes pixel-perfect snapshots of real code, styling, and assets. Your tests reflect what your users actually experience.
Low maintenance - high coverage
Chromatic creates tests from the Storybook stories already created during the development process. No need to write the same tests twice.
No test flake
Our custom detection algorithm eliminates flakiness from latency, animations, resource loading, and browser state.
Playwright and Cypress logos
Not using Storybook? Chromatic integrates with Playwright and Cypress to provide comprehensive visual coverage for your E2E tests.

Scan all possible UI states to pinpoint regressions

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