Easy integration

Integrate Happo with Cypress in minutes. Use your existing tests and inject Happo screenshots for key UI states.

View setup instructions

Stable & cross-browser

Happo captures screenshots in real browsers — Chrome, Firefox, Safari, Edge and iOS Safari. We parallize test runs across our large fleet of browsers to give you fast results.

Responsive testing

Tell Happo to take screenshots in different viewport sizes. This will ensure your UI looks good no matter what device they are rendered on.

Configure viewport sizes

CI integration

With minimal setup, Happo will run with your Cypress tests in your CI/CD pipeline. We support GitHub, Bitbucket, Azure, CircleCI, and more.

Less flake

Happo will automatically silence animations, wait for asynchronous assets, fonts, and more. And you can specify a color-delta tolerance for visual changes so that you don't have to worry about minor differences.

Happo allows us to make changes to components used on hundreds of screens and upgrade core UI dependencies with confidence. It has been a big productivity boost over our previous workflow.

Happo is a straight up life-saver. How many times did you think your change was contained only to discover that ten other teams started using what you built, and your change breaks three of the ten? Without Happo, you might not know.

Happo supports the latest versions of most browsers and emulators. Their speed of image comparison is impressive. They also have Github and CI integration and plugins to support Storybook and Cypress directly.

Spot differences with ease

Happo's set of tools make it easy to spot differences between screenshots. When side by side isn't enough, the Diff view will highlight exactly where the change is located, and the swipe view allows you to quickly switch between the before and after.

To reduce noise, you can set a color-delta tolerance for visual changes. Happo will then treat changes below this threshold as noise and ignore them. This is great for image compression noise, anti-aliasing, and other minor differences.
