Visual diffs without the flake tax

Pixel-perfect compares are only useful if they fail for the right reasons. Font hinting, sub-pixel antialiasing, and lazy-loaded heroes will light up a 0.0 threshold every time — and trains the team to ignore the alert.

ShipCheck’s visual diff lets you raise tolerance just enough to absorb noise while still catching real layout shifts. Prefer comparing stable viewports, hide known dynamic regions when you can, and treat diffs as evidence — not the only gate.

For “is the checkout path still clickable?”, start with browser smoke tests instead of screenshots alone.
