Next.js vs React: Which Should You Use for AI-Built Projects?

TL;DR: Use Next.js

When asking AI to build your project, Next.js almost always produces better results than vanilla React. Here's why.

Why Next.js Wins

1. Batteries Included Next.js comes with routing, image optimization, API routes, and server components out of the box. This means your prompt can focus on features rather than configuration.

2. AI Has More Training Data Claude, GPT-4, and other models have seen millions of Next.js projects. The quality of AI-generated Next.js code is consistently higher than less common frameworks.

3. App Router is Opinionated The file-based routing and layout system gives AI a clear mental model. The generated code tends to be well-structured.

4. Vercel Deployment One-click Vercel deployment means you can go from AI-generated code to live site in minutes.

When React Makes Sense

- You're building a SPA that needs to integrate into an existing non-Next.js project - You have specific hosting requirements that don't work well with Next.js - You're building an Electron or React Native app

The Verdict

For 90% of websites — landing pages, SaaS apps, portfolios, e-commerce — Next.js is the right choice. Specify it in your AI prompt and you'll get cleaner, more structured output every time.
