React vs Next.js: What We Recommend to Clients in Kathmandu, Nepal

React and Next.js come up in nearly every technical conversation we have with clients in Kathmandu, Nepal, often used interchangeably even though they solve different problems. React is a JavaScript library for building user interfaces. Next.js is a framework built on top of React that adds routing, server-side rendering, and a structured way to organize a full application. The two are not competitors; Next.js exists because plain React needs a lot of additional tooling to become a production-ready website.

For a marketing website or e-commerce store where search engine visibility matters, we default to Next.js because it renders pages on the server, which search engines can index far more reliably than a client-only React app. It also gives us built-in image optimization and routing conventions that speed up development.

Plain React still has its place for internal tools, admin dashboards, or single-page applications where SEO is irrelevant and the priority is a fast, interactive interface behind a login. Choosing between them comes down to one question: does this application need to be found on Google, or does it live behind authentication?
