Automated Visual Testing for React & Vue

Instantly get UI tests across your React & Vue components

How Screener works


Write Docs

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.

Instant Tests

Dramatically reduce the time it takes to write 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 assertions, while testing both functional and visual aspects of your UIs.

Natural Workflow

Simply develop your components in Storybook, and automatically get living documentation and automated UI tests at the same time.

Smart Diff

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.
