Next.js accessibility checker

Next.js blends static and dynamic rendering. Accessibility depends on final HTML, hydration behavior, and client components that manage focus.

Run a free scan

Scan production or preview deployments. Test both marketing pages and authenticated flows if you expose safe staging URLs.

What to scan

Prioritize templates with interactive components: navigation, search, carts, and account settings. Marketing pages often fail on contrast and headings.

Images and LCP

Use next/image with meaningful alt text. Decorative images should carry empty alt. Large hero media can shift layout; accessibility and performance overlap.

Internationalization

Set correct lang attributes per locale. Mixed-language pages confuse screen readers when language is not announced.

Deployment checks

Scan after major refactors. Compare public report URLs to track regressions across releases.
