Instantly get UI tests across your React components
How Screener works
Document the different states of your UI components using Storybook.
Get Automated UI Tests
Screener will use each component state as a visual test case for automated testing.
Review Visual Changes
Screener will automatically detect and report on visual regressions.
Dramatically reduce the time it takes to setup and maintain automated UI tests, so that you can focus on your project code, not test code, and deliver faster.
Less Code, More Coverage
A single visual snapshot with Screener can replace hundreds of coded expectations, while testing both functional and visual aspects of your UIs.
Release with Confidence
Be confident moving quickly and making code changes, knowing that if there are any visual or functional issues, we’ve got you covered.
See what sets Screener apart
Screener's Smart Diff algorithm understands your UI, automatically deciphering structure, layout, content and styling, allowing it to know and control what is being compared. Unlike pixel-to-pixel image diffs which have high false positives.
