Thinking of visual testing using Chromatic or one of the other Percy competitors?
It can be time-consuming to scan each feature of every tool, so we gathered some handy info that’ll make it easier to decide which visual regression testing tool is right for you.
Read on for an overview of Chromatic and Percy, including features, workflows, and pricing. We hope this helps you figure out the best testing solution for your project.
Modern view layers like React, Angular, and Vue help you divide complex UIs into simple components. Visual testing at the level of components makes it easier to scope tests and identify regressions. Chromatic is centered around organizing, managing, and visually testing components.
In comparison, Percy and its competitors were originally built to visually test pages. Testing at the page-level in a componentized app results in a flood of false positives and painfully sorting through the test failures.
Chromatic was built from the ground up to work best with components. With Chromatic, every UI component in your app is tracked separately each commit so you can see how a component changes whenever you push code. Chromatic is in tune with how frontend developers build modular UIs.
It takes a team to build a full-featured app. Like you, we understand that complexity grows and communication muddies the larger the team and project. That’s why Chromatic was built for collaboration from the start.
App teams can review UI changes together in one place. Engineers, designers, and product managers can browse the component library online without needing to pull code, migrate, or maintain a dev environment. No more “this doesn’t work on my machine”.
Storybook helps frontend teams ship components. Chromatic automates visual testing those components.
As maintainers and sponsors of Storybook, we understand how integral Storybook is to app teams. That’s why we’re dead set on building a tool to improve your Storybook workflow without adding extra work.
Chromatic tests map 1-to-1 with your stories. Whenever you update a story your tests are synced. This means visual tests are painless to keep up to date.
Every time you push code, the components in your Storybook are uploaded to Chromatic. This means everyone on your team can participate in reviewing. No pulling code required.
Work on features together or separately. With branching and merging, you can make as many feature-branches as you need and seamlessly merge them back into production. It all happens behind the scenes, and just works. No configuration needed.
Chromatic doesn’t just capture an image of each component, it’s a living re-creation of component’s DOM, styling, and assets. Whenever you’re reviewing changes, you see high-fidelity components that are fully inspectable. This makes it painless to reproduce and confirm component changes because you see exactly what your users see.
Everyone wins when you test UIs. Developers spend less effort fixing cryptic bugs. Users get pixel-perfect experiences. Designers and product people can ensure UI consistency without extra work. QA people don’t have to sink time into manual tests.
We believe UI testing should be ubiquitous and accessible. Chromatic’s pricing plans reflect that:
|Concurrency||✅ Max ¹||"Dynamic"|
|Inspectable code||✅ Yes||No|
|Component history||✅ Yes||No|
You save $360 a year for equivalent snapshot usage. What's more, Chromatic is made for components and component libraries. You get the work-saving benefits of faster testing, intuitive review flows, fully inspectable components indexed online, and individual component history. It's ideal for modern web app and frontend infrastructure developers.
