AI-generated diff summaries

- Prioritizes by impact, so a shifted header outranks a new testimonial
- Skim the summary in seconds instead of opening every screenshot pair

Use cases
Diffy fits wherever visual accuracy matters.
Compare any environments
Catch regressions before they reach users by comparing production against staging, dev, or any other environment side by side.
Regular monitoring
Schedule automated screenshot comparisons on a cadence so unexpected changes — broken layouts, missing content, style drift — are flagged the moment they appear.
Screenshots vs. Figma designs
Verify that implemented pages match approved designs by comparing live screenshots directly against exported Figma frames.
Diffy supports your team with an extra set of eyes
So your colleagues do not need to check pages manually.
