React (Client-Side)
Best for: SPAs, dashboards, internal tools, apps behind login. Pure client-side rendering. Maximum flexibility.
Next.js (Full-Stack)
Best for: Marketing sites, e-commerce, blogs, SEO-critical pages. Server-side rendering + static generation. Built-in routing, image optimization, API routes.
The Decision
Need SEO? Next.js. Building a dashboard? React. Want both? Next.js with client components where needed. At RioCloud, we build with both — choosing based on the project requirements, not framework hype.
