Q1. What is the difference between Server Components and Client Components in Next.js?

Next.js is the leading React framework for building production-grade web applications, combining server-side rendering, static site generation, and client-side interactivity in a single unified model. With the App Router and Server Components, it gives teams a fast path from prototype to a fully production-ready, SEO-friendly application.

If SEO, page load speed, and server-rendered content matter for your product — a marketing site, a content platform, an eCommerce store, or a SaaS app that needs shareable, indexable pages — a dedicated Next.js developer is the right fit. They bring expertise in rendering strategy, Server Components, and the App Router that a plain React setup doesn't offer out of the box.
A plain React developer (with a tool like Vite) makes more sense for internal tools, admin dashboards, or authenticated-only applications where SEO is irrelevant and a simpler client-side-only setup is faster to build and reason about.
Use these questions when evaluating Next.js developers — or let us handle the vetting.
Tests currency of knowledge — should explain where each runs and when to use "use client"
Should compare trade-offs for freshness, build time, and traffic patterns
Should describe mutations without a separate API route and their security considerations
Look for image optimization, font loading strategy, and minimizing client JS
Should reference middleware, session handling, and libraries like NextAuth/Auth.js
Should mention fetching in Server Components and caching behavior
Look for a phased routing and rendering migration plan, not a risky full rewrite
