React
A UI library used in client-rendered apps and full-stack frameworks. In a custom setup, you select the surrounding tools.

React vs Next.js: library and framework.
A clear, non-technical React vs Next.js comparison for teams choosing a web stack for marketing sites, apps, and eCommerce products.
( summary )
Choose how much tooling to assemble.
A framework provides integrated choices for routing and data loading. A custom setup lets you select those tools, with responsibility for keeping them working together.
Next.js
A React framework with integrated routing, server and client rendering, data loading and deployment conventions.

Scroll across to see all columns.
| Factor | Client-rendered React setup | Next.js |
|---|---|---|
| Foundation | React plus selected libraries and build tools | Integrated React framework |
| Routing | Manual or third-party | File-based, built in |
| Public content | Check that crawlers can access rendered content | HTML rendering and metadata tools available |
| Rendering | Browser rendering in this setup | Build-time, server and client rendering options |
| Server code | Usually a separate backend | Route Handlers and server functions on supported deployments |
| Useful when | Existing client and backend tooling fits the task | Integrated routing and rendering fit the architecture |

Common questions
What is the difference between React and Next.js?
React is a library for building interfaces. Next.js is one framework built around React, with routing, rendering and server features integrated. React can also be used with other frameworks or with tools you select yourself.
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?
Next.js provides rendering and metadata tools that help make content available to crawlers. Other React setups can also render HTML on the server or at build time. Search visibility depends on the implementation and content, not the framework name.
When should I just use React instead of Next.js?
A client-rendered React app can suit an interface with a separate backend when your team already has suitable routing and data tools. React can also use other full-stack frameworks. Choose based on deployment constraints, rendering needs and existing architecture.
Can Udaan build with React or Next.js?
Yes. We build React interfaces and Next.js applications, choosing the setup after reviewing the content, interactions, backend and deployment requirements.
How do I choose?
First decide what belongs in the browser, what needs server rendering and how the app will be hosted. Then compare Next.js with another React framework or your existing tooling, including maintenance and team experience.
