React and Next.js for business websites: why speed is a feature

We build business websites in React and Next.js when speed, custom functionality or a headless CMS really matter. Next.js can pre-render pages and serve them from the edge, which makes them load very quickly, and it handles app-like features (logins, calculators, dashboards, integrations) without bolting plugins onto a theme. If you just need a brochure site that marketers can edit visually, WordPress or Webflow is usually the more practical choice.

Why speed is a feature, not a nice-to-have

Visitors notice slow pages, and search engines measure them. Google's Core Web Vitals look at how fast the main content appears (Largest Contentful Paint), how quickly the page responds to taps and clicks (Interaction to Next Paint, which replaced First Input Delay in 2024), and whether the layout jumps around while loading (Cumulative Layout Shift).

Speed affects more than rankings. A slow mobile page makes a paid ad click more expensive, makes a lead form feel unreliable and makes a brand look careless. When a site is the main way a business wins customers, performance is part of the product.

You can build fast sites on many platforms. Next.js makes it the default rather than something you fight for.

React and Next.js, briefly

React is a JavaScript library for building interfaces out of components: a header, a pricing card, a testimonial slider. Each component is reusable and testable.

Next.js is a framework built on React. It adds what a real website needs:

• File-based routing. Pages and URLs map cleanly to the project structure.
• Rendering choices per page. Static generation, server rendering or a mix, decided page by page.
• Image optimization. Images are resized, compressed and served in modern formats automatically.
• Metadata and SEO tools. Titles, descriptions, Open Graph tags and sitemaps are built into the framework.
• Server-side code. Form handlers, API routes and integrations live in the same project.

The current App Router and React Server Components let much of the work happen on the server, so less JavaScript is sent to the browser.

How Next.js makes pages fast

Most business sites we build are mostly static, with a few dynamic pieces. Visitors get pre-built HTML from a server near them, which is about as fast as the web gets.

What Next.js is great at

Custom functionality

Quote calculators, booking flows, member portals, product configurators and CRM integrations are ordinary React and server code. You are not stitching together plugins that were never designed to work together. Our web app and integrations work usually starts here.

Headless CMS front ends

Next.js is the most common front end for a headless CMS. Content lives in Contentful, Sanity or headless WordPress, and Next.js renders it into fast pages. If you are new to the idea, read what is a headless CMS, and do you need one?.

Headless commerce

Shopify and BigCommerce both support headless builds, where the platform runs products, cart and checkout while Next.js runs the storefront. It is a strong option for established brands that want a fully custom experience. Our ecommerce platform comparison covers the commerce side.

Security surface

A mostly static Next.js site has no public admin login and no plugin stack on the same server. That removes common attack paths, though dependencies still need updating like any software.

Where Next.js is overkill

Next.js is not the right answer for every project:

• Content-heavy blogs where editors want everything in one place. WordPress still wins here for most teams, for the reasons in why we still choose WordPress for blogs and content sites.
• Design-led marketing sites that marketers want to control visually. Webflow gives designers and marketers direct control with clean output. See when Webflow is the right call.
• Small budgets and simple needs. A five-page site does not need a custom codebase.
• No one to maintain it. A Next.js site is software. It needs a developer or care plan to update dependencies and make changes.

Next.js vs WordPress vs Webflow

We do not sell one tool. We pick per project, and plenty of clients use more than one: a Next.js marketing site with a WordPress-powered blog, for example.

What a Next.js project involves

A typical build includes:

1. Content modeling. Defining the content types and reusable blocks marketers will use.
2. Design system. Components built once in React, styled consistently.
3. CMS integration and preview. Editors see drafts before they publish.
4. SEO foundations. Metadata, structured data, sitemaps, redirects and analytics.
5. Hosting and deployment. Usually on a platform built for Next.js, with preview deployments for every change.
6. Ongoing care. Dependency updates, monitoring and small improvements.

Because more of the work is custom, Next.js projects usually start higher than a theme-based build. Our website cost guide explains the range.

How we'd decide

Choose Next.js when speed is part of your competitive edge, when the site needs real application features, or when content must flow from a headless CMS into a custom front end. Choose WordPress or Webflow when editors need to own most of the site and the functionality is standard. If you are unsure, start by listing the features the site must have in two years; the right platform usually becomes obvious.
