How to Evaluate a Next.js Template Before You Ship

List every route, navigation destination, form, modal, carousel, filter, and timed effect before judging the visuals. Mark which controls are local demonstrations and which connect to real product behavior. A polished frontend does not imply authentication, checkout, email delivery, analytics, or a CMS.

• Open every internal link and intentional external destination.
• Replay hover, focus, keyboard, touch, and reduced-motion states.
• Test direct navigation and refresh on each route.
• Record placeholder content and controls that need integration.

Review where client directives, animation libraries, and browser APIs enter the tree. Confirm template styles are scoped and do not depend on marketplace globals. Check the package manifest, lockfile, scripts, aliases, image configuration, and font loading before copying files.

Build the standalone package, not only the marketplace preview. The archive should render the same sections and should not require a parent application’s CSS or undocumented environment variables.

Compare the full page at narrow mobile, tablet, and desktop widths. Look for intentional rearrangement rather than simple shrinking. Then inspect heading order, landmarks, focus order, control names, contrast, text zoom, and error messaging with final content.

• Test long titles, translated copy, and realistic data.
• Confirm sticky and fixed layers do not obscure focused controls.
• Check media alternatives and decorative-image treatment.
• Verify reduced motion changes every continuous or spatial effect.

A template can provide useful semantics without guaranteeing that a customized product meets an accessibility standard. Validate the shipped product in its final context.

Read the software license and attribution requirements. Then audit photographs, videos, illustrations, fonts, logos, trademarks, and likenesses separately. A permissive code license does not establish redistribution rights for every bundled asset.

• Record the source and license evidence for every retained asset.
• Replace remote hotlinks with cleared local assets.
• Remove customer names and performance claims you cannot support.
• Do not enable sale or release when rights remain unknown.

1. Run formatting, typecheck, tests, and a clean production build.
2. Compare the standalone package and live preview at key widths.
3. Record browser behavior separately from build success.
4. Document asset and license status separately from source quality.
5. List remaining integration work and known discrepancies.
