Next.js

What Is Next.js?

Next.js is a React framework maintained by Vercel that provides file-based routing, multiple rendering strategies (SSG, SSR, ISR), API routes, and an opinionated project structure. It is the most widely adopted React framework in production and has the largest ecosystem of tutorials, plugins, and hiring pool of any modern framework.

The App Router (introduced in Next.js 13, stable in 14+) brought React Server Components to production, a fundamental shift that moves data fetching and rendering to the server by default, reducing client-side JavaScript and enabling streaming UI patterns.

Key Features

• App Router - file-based routing with React Server Components and streaming
• React Server Components - server-rendered components with zero client bundle contribution
• Multiple rendering modes - SSG, SSR, ISR (incremental static regeneration) per route
• Server Actions - colocated server mutations without separate API routes
• Image component - automatic optimization, resizing, and lazy loading
• Font optimization - automatic font subsetting and self-hosting
• Middleware - edge-based request processing for auth, redirects, A/B testing
• API routes - serverless API endpoints alongside frontend pages

Pricing

Next.js is open source and free. It runs on any Node.js host, Vercel (the creators), AWS, Railway, Fly.io, or self-managed servers. Vercel's platform is the most seamless deployment target and has a generous free tier, with team plans starting at $20/month.

For enterprises, Vercel Enterprise offers SLA, SSO, and dedicated support. Self-hosting on AWS or GCP is practical but requires more configuration for features like ISR and edge middleware.

Our Experience

Next.js is our primary framework for complex web applications, e-commerce platforms, SaaS dashboards, and applications that combine content delivery with authenticated user experiences. The App Router's React Server Components model is a meaningful improvement over the Pages Router for data-heavy applications: streaming, partial prerendering, and server actions reduce both bundle sizes and waterfall fetching patterns.

The TypeScript integration is excellent. Ecosystem depth is unmatched, virtually every library, authentication provider, and third-party integration publishes a Next.js guide or first-class SDK. For teams hiring React developers, Next.js is the safe choice because it's what most React developers already know.

The tradeoff: for purely content-driven sites without complex interactivity, Next.js carries more complexity than necessary. Astro will outperform it on Core Web Vitals for content pages. And the App Router, while powerful, has a steeper learning curve that can slow teams down initially.

When Lucky Media Recommends Next.js

We reach for Next.js when:

• The project is a complex web application, SaaS, e-commerce, authenticated dashboard
• The team is React-proficient and needs a full-stack framework
• The product mixes content pages with dynamic, authenticated sections
• Enterprise reliability, ecosystem depth, and hiring pool are considerations
• The project needs fine-grained rendering control per route (static some pages, SSR others)

We'd suggest alternatives when:

• The project is a marketing site or content-only property (use Astro for better performance)
• The team is Vue-based (use Nuxt)
• The project needs a simpler mental model for data loading (consider Remix)

faq

Is Next.js frontend or backend?

Both. Next.js is a full-stack framework: it handles the React frontend and server-side logic in a single codebase. API routes run on the server, Server Components fetch data server-side, and Client Components handle interactivity in the browser. You can build a complete application, frontend, API, and data fetching, without a separate backend service.

Why are people leaving Next.js?

The two most common reasons are Vercel pricing concerns at scale, and the App Router's learning curve and complexity. The App Router introduced a fundamentally new mental model (Server Components, async components, server actions) that is powerful but requires significant rethinking for teams accustomed to the Pages Router. For projects where these concerns are real, Astro, Remix, Tanstack Start are the most common alternatives.

Is Next.js basically React?

Next.js is React, plus routing, rendering, server-side data fetching, and deployment tooling built on top of it. React is a UI library, it renders components. Next.js is a framework that adds the structure needed to build a complete production application. Every Next.js app uses React; not every React app uses Next.js.

Do I need Vercel to run Next.js?

No. Next.js is open source and runs on any Node.js hosting environment like Render, Railway, AWS, Google Cloud, or a self-managed server. Some features (ISR, Edge Middleware, partial prerendering) work best or are optimized on Vercel, but the core framework is fully portable. Lucky Media deploys Next.js projects to Vercel, Render, and AWS depending on the project requirements.

Next.js vs Astro: which should I choose?

Choose Astro for marketing sites, content properties, and documentation where performance and SEO are the primary criteria, it ships less JavaScript and produces faster-loading pages by default. Choose Next.js for complex web applications, SaaS products, e-commerce, or anything with significant interactivity and full-stack data requirements. Lucky Media uses both in production.
