The Short Answer
If you're building a public-facing website that needs SEO, use Next.js. If you're building an internal dashboard where SEO doesn't matter, plain React is fine.
What is React?
React is a UI library for building component-based interfaces. It runs entirely in the browser (client-side rendering).
- Good for: SPAs, admin dashboards, internal tools
- Not great for: Public websites where SEO and initial load time matter
What is Next.js?
Next.js adds SSR, SSG, ISR, and the App Router on top of React, giving you the component model plus full SEO support and built-in image optimisation.
- Good for: Marketing sites, e-commerce, blogs, portfolios
Key Differences
- Rendering: React = CSR only. Next.js = SSR, SSG, ISR, CSR — you choose per page.
- SEO: React needs extra setup. Next.js has a built-in metadata API.
- Images: Next.js has automatic optimisation, WebP conversion, and lazy loading.
- Performance: Next.js wins out of the box with automatic code splitting.
