Questions buyers ask
What is the difference between React and Next.js?
React is a JavaScript library for building user interfaces with components. Next.js is a framework built on React that adds routing, server-side rendering, static generation, APIs, and tooling to ship full applications.
Do I need React before Next.js?
Yes, in practice. Next.js is React under the hood, so knowing React components, props, and state is the foundation. Next.js layers project structure and rendering on top.
Is Next.js better than plain React for SEO?
Usually. Next.js gives you server-side rendering and static generation out of the box, which makes pages easier for search engines and AI answer engines to crawl than a purely client-rendered React app.
When should I just use React instead of Next.js?
Choose plain React for highly interactive, client-heavy apps like dashboards and tools that don't need SEO, SSR, or file-based routing, and where a custom setup is fine.
Can Udaan build with React or Next.js?
Yes. We deliver both, and for marketing sites, eCommerce, and content products we typically recommend Next.js for its SEO, speed, and developer ergonomics.
How do I choose?
Pick Next.js for full apps that need SEO, routing, and server rendering. Pick React alone for client-heavy interactive interfaces where search visibility matters less.
