React is the most widely used frontend framework in professional development today. The 2025 Stack Overflow Developer Survey found that 44.7% of professional developers use React, more than Angular, Vue, and Svelte combined. Over 53 million live websites run React on their frontend, and 80% of Fortune 500 companies use it in production. React Native, its mobile counterpart, powers more than 12% of the top 500 US mobile apps and is the second most widely used cross-platform framework globally. When you hire React developers from KiwiCommerce, you get UK-based specialists across both React.js web development and React Native mobile app development, on current versions, built properly.
React.js and React Native serve different purposes and attract different buyer profiles. Some businesses need web application development. Others need a cross-platform mobile app. Some need both. Our React.js development team and React Native app development specialists work with businesses at each of those points.
Get In TouchYou are building a single-page application, a SaaS product frontend, a customer-facing dashboard, or an eCommerce storefront using Next.js with React. These projects need dedicated React.js developers who understand component architecture, state management, server-side rendering, and how to build UIs that stay performant as they grow in complexity.
You need a mobile app for iOS and Android without building and maintaining two separate native codebases. React Native lets your developers share a significant portion of code across both platforms while producing a genuine native mobile experience. Our dedicated React Native developers build mobile commerce apps, delivery services, dashboards, fintech applications, and other business-critical mobile products.
Headless commerce architectures use React.js or Next.js as the frontend layer, decoupled from the commerce backend. Whether you are running a headless Shopify, headless Magento, or a custom backend, a React.js development team builds the storefront. Our developers understand eCommerce in depth alongside React, which makes a genuine difference to how product pages, checkout flows, and performance are handled.
You are a digital or development agency with React or React Native work on a client account, and you need a dedicated React developer or a React.js development team to deliver it under your brand. We provide React developers and React Native app developers as a white-label resource, operating under your agency name with no reference to KiwiCommerce.
React.js and React Native share a creator (Meta), a language (JavaScript and JSX), and a component-based architecture. Beyond that, they are built for different platforms and serve different purposes. Knowing which one your project actually needs avoids hiring the wrong developer for the job.
React.js is a JavaScript library for building web user interfaces. It renders to the browser's DOM and produces the HTML, CSS, and JavaScript that web browsers deliver to users. React 19, released in December 2024 and now the widely-adopted stable version, brought significant changes to how React handles data fetching and rendering with React Server Components, the new Actions API, and a React Compiler that reduces unnecessary re-renders. Next.js 16, the leading React framework, used by 68% of React developers, enables server-side rendering, static generation, and full-stack application development on top of React.
React Native is a framework for building cross-platform mobile applications for iOS and Android using JavaScript and React's component model. Instead of rendering to the DOM, React Native translates components into native UI elements on each platform. A React Native app installs on a device like a native app. It is not a web app wrapped in a browser view. The Hermes JavaScript engine and the Fabric rendering architecture have significantly narrowed the performance gap with fully native apps for most real-world use cases: eCommerce apps, delivery platforms, dashboards, fintech tools, and productivity applications.
Our React.js and React Native developers build across the full range:
2+ Experience Years
Builds React components to a defined spec with senior oversight. Understands JSX, props, state, and basic hooks (useState, useEffect). Can implement UI screens from a Figma design within an existing codebase and component library. Not suited for architecture decisions, state management design, or performance optimisation without guidance.
5+ Experience Years
Owns complete React features end-to-end. Comfortable with TypeScript, advanced hooks, state management libraries (Redux, Zustand, React Query), RESTful, and GraphQL API integration and responsive UI implementation. Writes code that other developers can read and maintain. Works independently on mid-complexity React web applications and Next.js projects.
7+ Experience Years
Designs React application architecture from the ground up. Deep understanding of React 19 patterns, including Server Components, the Actions API, and the React Compiler. Experienced with Next.js full-stack patterns, performance profiling, bundle optimisation, accessibility, and the long-term maintainability of large React codebases. Makes the architectural decisions that determine whether a React application scales cleanly or becomes a rewrite project two years later.
5+ Experience Years
Specialist in building and maintaining cross-platform mobile applications using React Native. Understands the differences between React Native components and their web equivalents, navigation libraries (React Navigation), native module integration, platform-specific styling, Expo vs bare React Native build workflows, and App Store and Google Play submission processes. For businesses building or maintaining mobile apps rather than web applications.
5+ Experience Years
Senior React Native developers and leads for businesses needing a full React Native app development agency arrangement rather than a single developer. These are experienced mobile engineers who lead React Native builds from architecture through to release: state management, push notifications, device API integration, in-app payments, performance profiling, and app store compliance. Best suited for commercially critical mobile products.
4+ Mixed levels
Combines strong React.js frontend skills with backend proficiency in Node.js, PHP, or Python. Builds complete web applications where frontend and backend are developed by the same person or under tight technical leadership. Experienced with Next.js as a full-stack framework, REST and GraphQL API design, database integration, and deployment pipelines. Reduces the coordination overhead between separate frontend and backend teams on smaller builds.
Most React agencies focus on either web or mobile. KiwiCommerce provides both React.js web developers and dedicated React Native app developers, which matters when a project involves both platforms, or when a business wants a single development partner rather than separate agencies managing web and mobile. We understand how the two ecosystems relate to and where they differ, and we build each one correctly.
Every React developer is based in the UK. Communication happens within working hours. For projects with daily standup calls, regular design reviews, or fast-moving development cycles, that timezone alignment is a delivery requirement rather than a nice-to-have. You do not lose a working day between every question and answer.
KiwiCommerce's background is in eCommerce development across Shopify, Magento, and WooCommerce. When our React.js developers build eCommerce frontends, headless storefronts, or product page components, they bring genuine eCommerce knowledge alongside React expertise. They understand how product listings should render for performance, how checkout flows affect conversion, and what Core Web Vitals mean in a retail context.
React 19 (stable, released December 2024) is the current version. Next.js 16 is the current full-stack React framework. Our developers work on current, supported versions and apply modern patterns, including React Server Components and the React Compiler. Older React patterns and deprecated approaches produce technical debt. Hiring developers who work on current versions from the start avoids expensive refactoring later.
Your codebase, product logic, and commercial plans stay private. Non-disclosure agreements are signed as standard on every React project, dedicated retainer, and React Native app development agency engagement. For agencies placing our developers on client accounts, we operate fully under your brand with no reference to KiwiCommerce in any deliverable.
Some React projects need a single dedicated React.js developer on a monthly retainer. Others need a React.js development team for a defined build phase. Some need React Native app developers for a mobile product alongside a separate web team. We structure the engagement around what the project actually requires and agree the arrangement clearly before development begins.
From first contact to a React developer working on your project, the process is direct and starts with understanding exactly what you are building.
Tell us whether you need React.js web development, React Native mobile development, or both. Share what you are building, the current state of any existing codebase, the frameworks in use, and the timeline. The distinction between React.js and React Native matters upfront because they require different developers with different specialisms. We respond within one business day with an honest assessment.
For projects involving an existing React.js or React Native application, our developer reviews the current codebase before agreeing a final scope. This covers the React version, state management approach, test coverage, component architecture, and any existing technical debt. For React Native mobile apps, we also assess the Expo or bare React Native setup, navigation structure, and native module dependencies. This review prevents surprises during development.
Based on your project React.js web app, Next.js full-stack build, React Native mobile app, headless eCommerce frontend, or dedicated retainer we identify the most suitable developer or team configuration from our team. You find out who will be working on the project before work begins. If you want to speak with the developer first, we can arrange that conversation.
Development proceeds in clear, documented stages with a staging environment for review before anything goes to production. For dedicated React developer retainers, the developer works from a maintained backlog with regular progress updates. For project-based React work, each milestone is reviewed and approved before the next begins. Code is committed to version control throughout and documentation is maintained.
At the conclusion of a project phase, we produce technical documentation covering component architecture, state management decisions, API integrations, and what a future developer needs to know to work on the codebase productively. For ongoing engagements, the same dedicated React developer continues as the technical lead. We also provide React and React Native support retainers for applications needing consistent, knowledgeable ongoing development.

React.js (also written as React or ReactJS) is a JavaScript library for building web user interfaces. It runs in the browser, renders to the DOM, and produces the HTML, CSS, and JavaScript that users interact with on websites and web applications. React.js is the right choice for web applications, SaaS products, dashboards, headless eCommerce frontends, and any UI that lives in a browser.
React Native is a framework for building cross-platform mobile applications for iOS and Android. It uses JavaScript and JSX like React.js, but instead of rendering to the DOM, it translates components into native UI elements on each mobile platform. A React Native app installs on a device from the App Store or Google Play and behaves like a native application, not a web app running in a browser view. React Native is the right choice for mobile apps where performance, device API access, and a native feel matter.
They share the component-based approach and JavaScript language, which means developers with strong React.js skills can transition to React Native, but they are not interchangeable. A React.js developer who has never worked on React Native will need time and experience to produce production-quality mobile apps. When hiring, specify clearly which platform your project targets.
React 19, released in December 2024, is the current stable version and now the standard for new React projects. It introduced the React Compiler (which handles performance optimisations automatically without manual memoisation), React Server Components at stable production quality, the Actions API for handling server-side data mutations, and native document metadata support. For projects using React 18 or earlier, upgrading to React 19 is straightforward for most applications and brings meaningful performance and developer experience improvements. Developers who are not working with React 19 patterns are already working with an outdated mental model.
Next.js is the most widely used React framework for production web applications, used by 68% of React developers. It builds on top of React and adds server-side rendering, static site generation, API routes, edge functions, and full-stack application patterns. Next.js 16 (released October 2025, with 16.1 as the latest stable version) is the current version. React Server Components, which are a core feature of React 19, are enabled by default in Next.js and are the standard architecture for new Next.js applications. For most web application projects requiring performance, SEO, and full-stack capability, Next.js is the correct React framework to use rather than a client-only React setup.
Yes to both. For businesses with an ongoing React.js web development need, we provide a dedicated React.js developer on a monthly retainer. For businesses maintaining or continuing to develop a React Native mobile app, we provide a dedicated React Native developer on the same basis. The dedicated model means the same developer works consistently on your codebase, building knowledge of the architecture and business logic over time. For larger projects needing a React.js development team or a full React Native app development agency arrangement, we provide and coordinate that team.
Yes. React Native’s core purpose is cross-platform development โ one codebase that runs on both iOS and Android. Our dedicated React Native app developers build apps that target both platforms, handling platform-specific styling where needed, testing on both operating systems, and managing the submission process for both the Apple App Store and Google Play. Where a feature requires access to a device-specific native API not covered by React Native’s core or existing community packages, our developers integrate custom native modules.
Yes, and this is an area where our background in eCommerce gives us a real advantage over a general React agency. Headless commerce architectures use React.js or Next.js as the frontend layer connected to a commerce backend through APIs. Our React.js developers have built headless storefronts for Shopify (using the Storefront API), headless Magento (Adobe Commerce), and custom commerce backends. They understand the eCommerce-specific challenges: how product pages should be structured for performance, how checkout flows affect conversion, how to handle inventory states in real time, and what Core Web Vitals mean in a retail context.
A freelance marketplace gives you access to individual developers of varying quality with no continuity, no account management, and no quality guarantee. You assess each candidate, manage the relationship, handle the handover when they move on, and carry the risk of inconsistent code quality across different hires. KiwiCommerce provides pre-assessed React.js and React Native developers with verified experience, managed as an engagement with a single point of contact. All code goes into version control. NDAs are signed as standard. If a developer changes, we manage the transition and knowledge handover. For dedicated React developer arrangements and React.js development team work, that structure matters.
Our UK-based React.js and React Native development team is ready to look at your project. Whether you need a dedicated React developer on a monthly retainer, a React Native app development agency for a mobile product, a React.js development team for a web build, or expert React developers for a headless eCommerce frontend, get in touch today. We respond within one business day.
