Automate visual QA for UI screenshots by comparing a generated screenshot against reference images to produce a deterministic JSON verdict. This structured output includes a numeric score, pass/revise/fail decision, mismatch differences, and suggestions to guide your next editing iteration.

Screenshot comparison for UI regression testing validates layout, spacing, typography, and component styling against a target appearance. It analyzes a generated UI screenshot alongside one or more reference images and returns a structured JSON verdict detailing category match and specific visual differences.

Yes, you can get a structured JSON verdict from a screenshot versus reference image comparison. The process returns deterministic JSON containing a numeric score, pass/revise/fail verdict, category match status, concrete differences, targeted suggestions, and a brief reasoning summary.

Validate layout and typography spacing by supplying your reference images and generated screenshot for comparison. The visual validation process checks these specific component styling attributes against the target appearance and highlights concrete mismatches in the returned JSON differences array.

Visual regression testing supports one or more reference images to accurately detect a UI layout diff. Supplying multiple reference images allows the comparison to validate the generated screenshot against various target appearances and return a comprehensive pass or fail verdict.

When UI redesign styling does not match the reference image target appearance, use the returned JSON suggestions and differences array. These targeted outputs identify specific layout, spacing, and typography mismatches to guide the precise component styling edits needed for your next iteration.
