Whether you’re launching a new SaaS platform, modernising an enterprise interface, or building a component-based design system, our team brings deep expertise in React and its surrounding ecosystem. We help you architect, develop, and optimise React applications that feel seamless, perform at scale, and stand the test of time.

Understanding React Development

React has become the framework of choice for modern web development — and for good reason. Developed and maintained by Meta, React allows for the creation of fast, dynamic interfaces through reusable components and a virtual DOM that improves rendering performance. It supports robust state management, easy integration with APIs, and compatibility with modern tooling — making it an ideal choice for building sophisticated frontend systems.

As a React development company, we use React to help organisations transform how users interact with their software. Whether you’re developing a customer-facing portal, an internal dashboard, or a full-scale single-page application, React provides the flexibility and power needed to deliver high-quality experiences across devices and platforms.

We build with React because it offers real development efficiency without compromising on maintainability or scalability. Its component-based structure makes it easy to expand applications over time, implement design systems, and manage complexity in large-scale projects. Combined with frameworks like Next.js, tools like Redux or Zustand, and integration with backend services, React offers an incredibly strong foundation for building modern digital products.

Our React Development Approach

At 6B, our React development process is tailored to your goals and technical environment. We begin by understanding your product vision, user needs, and the wider system landscape. This includes mapping out user journeys, defining technical requirements, and identifying opportunities to streamline interactions through smart, intuitive interfaces.

We take a component-first approach to frontend development, ensuring UI elements are consistent, accessible, and easy to maintain. Our team builds modular, testable codebases that support scalability from the very start — whether you’re launching a new MVP or evolving an enterprise system. We make use of leading tools and libraries in the React ecosystem to handle routing, state, forms, animations, and more, while ensuring clean integration with your APIs or backend services.

Throughout development, we work in agile sprints, delivering working interfaces early and often. We use code reviews, automated testing, and continuous integration to maintain quality and performance at every stage. We also collaborate closely with designers and backend developers to ensure the full product experience is cohesive, responsive, and optimised for real-world use.

Beyond the build, we provide ongoing support, performance tuning, and iterative enhancements — helping your React application stay fast, secure, and relevant as user needs evolve.

React Development FAQs

A React development company offers specialised expertise in building scalable, component-based applications. Unlike general frontend developers, a React-focused team can leverage advanced tools like Next.js, Redux, and Zustand to deliver faster, more maintainable, and high-performing web apps.

Yes. A React development company can integrate React frontends with a wide range of backends — from REST and GraphQL APIs to microservices and legacy systems — ensuring a seamless user experience without disrupting existing infrastructure.

React is ideal for SaaS platforms, single-page applications, internal dashboards, data visualisation tools, and customer portals. A React development company ensures these applications remain fast, responsive, and easy to scale as your user base grows.

React development companies follow WCAG accessibility standards, build reusable UI components, and conduct usability testing — ensuring your React app works for all users, including those with disabilities, across browsers and devices.

React is primarily used for building responsive web applications, while React Native allows for mobile app development on iOS and Android using the same JavaScript foundation. Many React development companies, including 6B, deliver both, enabling faster cross-platform product development.

Timelines depend on scope and complexity. A simple React MVP may be delivered in 6–10 weeks, while enterprise-grade platforms can take 4–9 months. A React development company provides a roadmap after discovery to ensure transparent planning.

React development companies optimise performance through techniques like code splitting, server-side rendering (with Next.js), caching, and virtual DOM efficiency — ensuring apps remain fast even with growing user traffic and complex data needs.
