Chromatic catches visual and functional bugs in your stories automatically. It runs UI tests across browsers, viewports, and themes to speed up frontend teams. Made by Storybook.
UI developers are responsible for component development, test, review, and documentation. This is often done manually. Chromatic automates these jobs and integrates them into your existing Git and CI tooling. That means you avoid tedious manual work while also saving time.
Sure, it’s possible to cobble together libraries to build some of Chromatic’s features – we’ve even published free guides and articles that share how. But then you’d have to invest time and effort into maintaining your DIY service instead of building valuable features for your customers.
Chromatic is a managed service that runs your tests in the cloud with a dedicated web UI for reviewing and approving changes. It’s much faster and more reliable than running tests locally because we maintain a fleet of standardized cloud browsers on your behalf. You get deterministic test results and fast test runs.
Our infrastructure is effectively capable of running all your tests in parallel, no matter how many builds you run, or stories you write. Customers can test 2000+ stories in less than a minute.
Since we maintain the infrastructure, we also take care of reliability, migrations, and security so you don’t have to. This means fewer questions from your teammates like “why did these tests fail on my machine?”.
