React SPA vs. Next.js
Client-Side vs. Server-Side Rendering
React SPAs are simpler to build. Next.js adds SSR, SSG, and API routes. The tradeoff is complexity vs. SEO and performance.
📊 Scoring Matrix
Poor (client-rendered)
Excellent (server-rendered)
Slow initial load (JS bundle)
Fast (server-streamed HTML)
Simple mental model

Any static host (cheap)
Needs Node server (Vercel)
Separate backend needed
Built-in API routes
Client downloads everything
Progressive loading
📋 Executive Summary
Next.js for content, marketing, and SEO-critical apps. React SPA for internal tools and dashboards.
Wrong rendering strategy costs 20-40% in SEO traffic or 30-50% in unnecessary hosting costs.
