One of the most frequent technical questions from clients and developers is: 'Should I build my product with standalone React (Create React App/Vite) or Next.js?' While both use React components under the hood, their architectural capabilities, rendering strategies, and SEO implications differ significantly.
Pure React uses Client-Side Rendering (CSR). Next.js offers Server-Side Rendering (SSR), Static Site Generation (SSG), Incremental Static Regeneration (ISR), Server Actions, and automatic image optimization.
Choose pure client-side React if you are building an internal admin dashboard behind an authentication wall where SEO is irrelevant, or an offline-first PWA where all logic runs entirely in the user's browser.
Choose Next.js for any public-facing product, SaaS landing page, portfolio, e-commerce store, or content platform. Server-Side Rendering and Static Site Generation ensure search engines index full HTML content while giving users instant page loads.
In LookADev, Next.js App Router powers the entire portfolio platform, achieving high Core Web Vitals scores and pre-rendering its project case studies as static HTML.
