Visual QA for Web & Apps

Match Every UI to Design
Deliver Pixel Perfect.

Q: What can I compare with Pixel Perfect UI?

You can compare a Figma frame or uploaded design image against a website URL, uploaded website screenshot, live mobile app capture, or uploaded app screenshot.

Q: What image formats are supported?

Design and implementation uploads support PNG, JPG, JPEG, and SVG files. A raster screenshot is best when you need a direct pixel-by-pixel comparison.

Q: How does the Figma integration work?

Connect with Figma OAuth or provide a Personal Access Token. Pixel Perfect UI extracts the file and frame identifiers from the Figma URL and fetches the selected design for comparison.

Q: Can I compare a mobile app with a Figma design?

Yes. Use a connected Android or iOS device to capture the running app, or upload an app screenshot, then compare it with a Figma frame or uploaded reference image.

Q: Can I compare private or staging websites?

Yes. Public URLs work directly, while supported login configuration can prepare authenticated website sessions before capture. You can also upload a screenshot when direct capture is not suitable.

Q: How accurate is the visual comparison?

The accuracy score reflects matched pixels across the compared images. Configurable tolerance, viewport, crop, and device controls help reduce false differences caused by sizing, system bars, anti-aliasing, or font rendering.

Compare Figma or image designs with websites and mobile apps.
Spot visual differences with heatmaps, scores, and reports.

The Problem

Design drift is invisible until it ships.

Spacing moves. Colors shift. Typography drifts. By the time a mismatch reaches production, trust between design, development, and QA is already eroded across web and mobile releases.

Manual QA Takes Forever

Teams lose hours per sprint comparing screenshots pixel by pixel.

Time wasted

Mismatches Go Unnoticed

Subtle drift compounds until the final UI feels inconsistent.

Quality suffers

Endless Back-and-Forth

Design, dev, and QA loops repeat without a single visual source of truth.

Trust erodes
