®React and Next.js are often mentioned as if they were rivals, but Next.js is built on top of React. The real question is whether your website or web app needs only React, or React plus the extra structure Next.js provides. The answer depends mostly on search visibility, how your pages are loaded and where you want to host.
How React and Next.js relate
React is a JavaScript library for building user interfaces. It handles components, state and updating the screen, but it leaves routing, data loading and page rendering to other tools. A typical React app today is set up with a build tool such as Vite and runs mainly in the browser.
Next.js is a framework built around React. It adds file-based routing, several ways to render pages on the server, image and font optimisation, and a way to write server-side code in the same project. When you use Next.js, you are still writing React components.
So the choice is not between two different technologies. It is between a lighter setup where you choose each piece yourself and a framework that makes many of those choices for you.
Server rendering and SEO
This is usually the deciding factor for public websites.
A plain React app normally sends the browser an almost empty page and then builds the content with JavaScript. Google can run JavaScript and index such pages, but rendering can be delayed, and other search engines, social media previews and some AI crawlers may handle it less well. Slow devices also take longer to show the first content.
Next.js can send fully formed HTML from the server. It supports several approaches:
- Static generation. Pages are built ahead of time and served as plain files. This suits marketing pages, blogs and documentation.
- Server rendering. Pages are built on each request. This suits content that changes often or depends on the user.
- Incremental updates. Static pages are rebuilt in the background after a set time or when content changes.
- Client rendering. Parts of a page still load in the browser where that makes sense.
Because the HTML arrives complete, search engines and link previews see the real content straight away. This also tends to help how quickly the main content appears, which feeds into Core Web Vitals. Our technical SEO checklist covers those signals in more detail.
Hosting and running costs
A plain React app compiles to static files. You can host it almost anywhere, including cheap static hosting and content delivery networks, with very little to maintain.
Next.js has more options. A fully static export can be hosted the same way, but you lose server features. Using server rendering means you need a platform that runs Node.js, such as Vercel, which develops Next.js, or other hosts and cloud services that support it. You can also run Next.js on your own server or in a Docker container.
Costs depend on traffic and on how much rendering happens on each request, so compare plans for your expected usage rather than assuming one option is always cheaper.
Side-by-side comparison
| Factor | React (with Vite) | Next.js |
|---|---|---|
| What it is | UI library plus a build tool | Full framework built on React |
| Default rendering | In the browser | Server or static, with browser rendering where needed |
| SEO for public pages | Workable, but needs extra effort | Strong by default |
| Routing | Add a library | Built in |
| Hosting | Any static host | Node.js host, or static export with limits |
| Learning curve | Lower | Higher, with more concepts |
| Best suited to | Dashboards, internal tools, apps behind a login | Marketing sites, blogs, shops, public web apps |
How to choose
Ask a few practical questions:
- Do strangers need to find these pages through search? If yes, lean towards Next.js or another server-rendering approach.
- Is the app mainly behind a login? Dashboards, admin panels and internal tools rarely need SEO, so plain React keeps things simpler.
- Is there an existing backend? If you already have an API in Laravel, Node.js or Python, a React front end can sit on top of it cleanly. Next.js also works with an existing API, but its server features may overlap with what you have.
- Who will maintain it? Next.js adds concepts such as server components and caching rules. A team new to React may find plain React easier to start with.
- Where must it be hosted? Company policy or existing infrastructure may favour static hosting or a particular cloud.
Many products use both. A Next.js site handles the public marketing pages and blog, while the product itself is a React app behind a login. That split keeps each part simple.
Common mistakes to avoid
- Choosing Next.js for an internal tool only because it is popular, then paying for complexity you do not use.
- Building a public content site as a plain React app, then trying to add SEO later.
- Ignoring caching settings in Next.js, which can lead to stale content or higher hosting bills.
- Mixing too much server and browser logic in one component, which makes the code harder to follow.
Frequently asked questions
Is Next.js better than React?
Not in general. Next.js is React with added features for routing and rendering. It is the better fit for public sites that need SEO, while plain React is often simpler for apps behind a login.
Can I move from React to Next.js later?
Yes. Your React components can usually be reused, but routing, data loading and some page structure will need rework. Planning the move early is cheaper than retrofitting a large app.
Does Google index React websites?
Google can render JavaScript and index React sites, but it may take longer and is less predictable than plain HTML. For pages where search traffic matters, server rendering or static generation is the safer choice.
