Implementation reviews usually rely on good eyesight and patience. Pixelay automates them. Load your Figma frame, overlay it on the build, and switch to diff mode to see exactly where pixels deviate. It’s like git diff, but for UI.

Beyond simple overlays

Pixelay offers heatmaps, split views, and tolerance controls. You can set an acceptable threshold (e.g., 2px) and quickly find sections that exceed it. This is perfect for teams with strict design systems.

Integrate with your sprint

Add Pixelay checks to your definition of done. Before shipping, engineers or designers run through the key flows, capture any differences, and fix them before QA signs off.

Implementation loop

1. Publish the final Figma frames to Pixelay.
2. Compare them to staging or local builds.
3. Log discrepancies with annotated screenshots and assign them to the right owner.

It’s unbelievably satisfying to sign off knowing the shipped UI matches what was approved.

Make it part of Definition of Done

Add a Pixelay comparison step to every story. Designers or QA can upload annotated diffs into your ticketing system, making acceptance criteria clear. Engineers quickly learn that builds won’t ship until the overlay looks perfect.
