Why teams switch to OverlayQA
Six QA workflows vs. bug reporting
Marker.io pairs bug reports with scheduled scans for accessibility, content quality and broken links. OverlayQA runs six workflows, including Visual Comparison against design specs, Auto Review for UI problems, and Accessibility Audit for WCAG compliance.
Design comparison, not just screenshots
OverlayQA compares the original design against the live page so you see exactly where the implementation deviates. Marker.io captures what the page looks like; its reviewed sources do not document design comparison.
AI-drafted issues with CSS context
Pin any element to capture its CSS values and screenshot. AI drafts a structured issue with the exact values developers need and exports to your project tracker in one click.
OverlayQA is the right pick when
Design-to-code verification teams
When your goal is verifying that builds match design specs, not just logging bugs with console output.
Faster, more precise issues
Pin an element, describe what's wrong, and AI drafts a complete issue with CSS context, instead of manually annotating screenshots.
Checks beyond accessibility and content
OverlayQA's Auto Review checks rendered UI, forms, responsive gaps and dead controls, and Visual Comparison checks the design. Marker.io's scans cover accessibility, content quality and broken links on your monitored pages.
