AI visual regression testing

Problem

Functional tests pass but the UI looks broken. CSS changes cascade unpredictably. Manual visual QA doesn't scale across browsers, devices, and screen sizes.

Solution

The AI agent captures screenshots across key pages, viewports, and browsers before and after each deployment. It compares images intelligently—ignoring dynamic content like timestamps while flagging genuine visual regressions.

Benefits

• Catch visual regressions before users do
• Cross-browser and cross-device coverage
• Intelligent comparison ignoring dynamic content
• Visual diff reports for easy review

How to get started

1. 1

   Define critical pages and viewports

   Select which pages, breakpoints, and browsers to monitor for visual changes.

2. 2

   Capture baselines

   The agent takes reference screenshots of your current production state.

3. 3

   Compare on each deploy

   On every deployment, the agent compares new screenshots to baselines and flags regressions with visual diffs.
