2026-05-22 · 7 min read

SEO and performance

Marketing pages and documentation benefit from server rendering and metadata APIs in Next.js.

Authenticated app shells can still be mostly client-rendered while keeping marketing routes fast and crawlable.

Team velocity

If your team already ships React, Next.js adds routing, data fetching patterns, and deployment ergonomics on Vercel.

Choose based on hiring pool and hosting, not hype.
