Changed-page screenshot preview in PR review
Attach screenshots and direct links to only the changed pages inside pull-request review so stakeholders can see what moved before they open the branch.
Why this can grow a startup
A lot of page review time is wasted on orientation. People first need to find the right URL, remember which screen changed, and build enough context to say something useful. Changed-page screenshots solve the first half of that immediately. They make the PR itself a growth review surface, which means copy, layout, and conversion issues get noticed earlier by people outside engineering.
Company example
Vercel's Deploy Summary analyzes pull requests, detects changed pages, and adds screenshots plus direct links to those pages next to the commit so teams can review faster.

When to use it
Use this when Website, Product Marketing, SEO is relevant to conversion, review velocity, landing pages and you can run a bounded test with a low budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
