Next.js Questions

Frequently asked questions about working with a Next.js development agency.

What is the difference between Next.js and React?

+

React is a UI library. Next.js is a full framework built on top of React that adds SSR, SSG, file-based routing, API routes, image optimisation and much more. For most production web applications, Next.js is the right choice.

Should I use App Router or Pages Router?

+

For new projects we always recommend the App Router (introduced in Next.js 13+). It supports React Server Components, streaming and nested layouts — critical features for modern, scalable web apps.

Can you migrate our existing React app to Next.js?

+

Yes, and it is one of our most common engagements. We migrate projects from Create React App, Vite and Gatsby to Next.js with better SEO, performance and developer experience.

How long does a typical Next.js project take?

+

A standard web application takes between 6 and 10 weeks from architecture to launch. Complex platforms with custom backends or e-commerce integrations can take between 3 and 6 months.
