What problem does it solve?

It prevents costly UI surprises by providing visual proof that HTML/CSS (and related rendered output) matches intended layout and behavior before you deliver changes to users.

Core Features & Use Cases

  • Screenshot-Based Visual Verification: Render pages in a headless browser and capture PNG screenshots for review or comparison.
  • Responsive Multi-Viewport Checks: Validate the same endpoint across multiple viewport sizes to catch breakpoint-specific regressions.
  • Interaction-Driven Evidence: Capture screenshots after user-like actions (click, scroll, hover, form interaction) to verify dynamic UI states.
  • Visual Regression Detection: Compare baseline and current PNGs using perceptual hashing to flag meaningful differences.
  • CI/CD Integration: Automate screenshot capture and upload artifacts in build pipelines for repeatable QA.

Quick Start

Use headless-browser-verification to capture PNG screenshots of the page in your local server and compare them against a baseline after your UI changes.
