The handoff is where design quality leaks
A design gets approved, built, and shipped — and nobody compares the two again. Spacing drifts, the wrong grey lands in production, a font weight is off by 100. None of it breaks a test, so none of it gets caught.
How it works
Add your design
Paste a Figma URL or upload a PNG or JPG. No plugin install, no setup.
Point at the live page
Enter the URL you want checked. QA Proof renders it in a real browser at the right viewport.
Get a scored report
Five category scores, visual markers on every difference, and copy-paste CSS fixes.
What you get in every report
Five scoring categories
Layout, colors, typography, spacing and components are scored separately, so you can see exactly where the build drifted.
Visual difference markers
Every finding is pinned to the exact element on the page — no hunting through a diff image.
CSS fix suggestions
Each difference comes with the specific property and value to change, ready to paste into your stylesheet.
Severity ratings
Findings are ranked so a broken layout doesn't sit in the same list as a 1px border radius.
Figma or image input
Connect Figma to keep designs in sync, or upload a static export when that's simpler.
API access
Run fidelity checks from your CI pipeline and gate merges on the score.
