Next.js vs React in 2026: Which Should You Build With?

People often frame this as "Next.js or React", but Next.js is React — with routing, rendering, and tooling built in. The real question is how much structure you need.

Choose plain React when

• You're building a widget or embedding into an existing app.
• You don't need SEO or server rendering.
• You already have your own routing and build setup.

Choose Next.js when

• SEO matters — server rendering and metadata are first-class.
• You want file-based routing, API routes, and image optimisation out of the box.
• You're building anything customer-facing that needs to load fast and rank.

For most marketing sites, e-commerce, and SaaS dashboards, Next.js is the default we reach for — it removes a week of setup and ships faster pages.
