React Development Services

React development services cover the design and build of user interfaces and web applications with React, the component library that powers most modern web products. Webcapitan builds React front ends for marketing websites, customer portals, dashboards and SaaS products, usually together with Next.js for server rendering and a Node.js or PHP back end. Our own website runs on React through Next.js, so the stack we recommend is the one we live with.

React is the right choice when an interface has real interactivity: forms with many steps, filters and configurators, live data, user accounts or anything that behaves like an application rather than a page. For a plain brochure site it is only worth it through Next.js, which turns React into fast, indexable pages. We explain that choice honestly at the start of every project.

What our React development services include

React web applications. Dashboards, portals, admin panels, booking and ordering flows, internal tools: typed components, state management, routing, forms and authentication.
React front ends for websites with Next.js: server-rendered or static pages, optimised images and fonts, metadata and structured data for SEO.
Design systems and component libraries. A documented set of components built from your Figma design, so every new screen is assembled rather than coded from scratch.
API integration. Connecting React to REST or GraphQL APIs, headless CMSs (Sanity, Strapi, headless WordPress), payment and CRM tools.
Migration to React. Moving jQuery, Angular, Vue or template-based interfaces to React step by step, without stopping the product.
Performance and code audits. Fixing slow React apps: bundle size, rendering strategy, memoisation, data fetching, Core Web Vitals.
Dedicated React developers who join your team for three months or longer, working in your repository and process.

Our React stack

Area	What we use
Framework	React 19 with Next.js (App Router) for websites; Vite for pure single-page apps
Language	TypeScript across components, hooks and API clients
State and data	React Query or SWR for server data, Zustand or Context for UI state, React Hook Form for forms
Styling	CSS Modules, SCSS or Tailwind, matching your design system
Testing	Vitest and React Testing Library for components, Playwright for end-to-end flows
Back end	Node.js (Express or NestJS), PHP or a headless CMS, depending on the project

How a React project runs

Discovery. We review the design, the data sources and the interactions, then send a fixed estimate by screen and feature with a schedule.
Foundation. Repository, TypeScript setup, design tokens and the core components, deployed to a staging URL in the first week.
Screens and features. Built in priority order in weekly increments with demos, connected to real APIs as soon as they are available.
Quality pass. Performance on a mid-range phone, accessibility (keyboard, screen reader, contrast), cross-browser checks, automated tests for the critical flows.
Launch and handover. Deployment, documentation, a walkthrough for your developers and a warranty period.

What React development costs

A React front end for a marketing website costs $5,000–20,000 and takes three to eight weeks; the interface of a web application costs $20,000–80,000 over two to six months. Hourly work with our team is $30–60, and a dedicated React developer is available from $4,000 a month. Every estimate is fixed and broken down by screen, so you can prioritise before work starts. See what front-end development services include and cost for the full picture.

React or something else?

Choose React when the interface is the product: many states, real-time data, complex forms. Choose Next.js on top of React for any public website, so pages arrive as ready HTML and rank well. Choose WordPress when a marketing team must edit and rearrange pages weekly without a developer, and Vue with Nuxt when your team already works in Vue. We build on all of them and will say which fits; read WordPress vs a custom CMS for the trade-offs.

Fixed estimates and a staging URL from week one.

FAQ

A React front end for a marketing website costs $5,000–20,000 and takes three to eight weeks; a web application interface costs $20,000–80,000 over two to six months. Hourly work is $30–60 with our team, and a dedicated React developer starts at $4,000 a month. Every estimate is fixed and itemised by screen.

On its own a React single-page app shows a blank page until JavaScript loads, which delays indexing. That is why we build public websites with Next.js on top of React: pages are rendered on the server or at build time, so search engines receive complete HTML with metadata and structured data.

Yes. We audit the code first, agree on conventions and then extend or refactor it in your repository with your review process. Dedicated developers can join your team for three months or longer.

Both deliver equally fast, accessible interfaces. Choose React for the largest talent pool and the Next.js ecosystem, Vue when your team or a Laravel back end already uses it. We build on both and recommend before you commit.

You do. The repository, components, documentation and deployment are handed over to you at launch, and any React developer can continue the work.
