A release checklist for comparing responsive screenshots and catching layout regressions across breakpoints.

6 min read - Updated 2026-05-13

Use this guide as a compact release reference, then validate the same breakpoints in Sizzy with synchronized devices and screenshot evidence.

Freeze the comparison state

Visual regression review needs matching conditions. Make sure baseline and candidate captures use the same route, viewport, account state, data state, and loaded assets.

Wait for fonts and images before capturing

Use the same logged-in or logged-out state

Disable or document dynamic banners

Keep full-page and above-fold captures separate

Prioritize release blockers

Small spacing changes can wait when conversion-critical UI is broken. Review navigation, CTAs, forms, dialogs, and sticky elements before polishing visual differences.

Primary CTA is visible and tappable

No text overlaps or clips

No unexpected horizontal scroll appears

Dialogs and menus fit at mobile widths

Release checklist

Use the same viewport matrix for every release comparison.

Label intentional design changes before review.

Separate blocking regressions from cosmetic differences.

Attach approved screenshots to the launch evidence packet.
