Where Next.js's own conventions help — and where accessibility is still entirely on you.
A few App Router conventions genuinely help by default. Route changes announce properly to screen readers because Next.js manages focus and page title updates during client-side navigation — something a naively built SPA router often gets wrong. next/image's required alt prop (which can deliberately be set to an empty string, but has to be set) at least forces a conscious decision about every image instead of silently letting one slip through unlabeled.
None of this replaces actually building accessible components. Semantic HTML, proper ARIA attributes where semantic HTML genuinely isn't enough, visible focus states, and full keyboard navigability remain entirely the developer's responsibility regardless of framework. One Next.js-specific pitfall worth knowing: heavy use of custom loading.tsx or Suspense boundaries can change what a screen reader announces during a loading transition if focus and live-region behavior aren't handled deliberately, since streaming in new content doesn't automatically come with the accessibility announcements a full page navigation would.
