React development for fast, maintainable interfaces
React is a JavaScript library for building user interfaces from reusable components. It is a strong choice for interactive applications such as dashboards, portals and SaaS products, where the interface changes constantly in response to data.
React has the largest ecosystem of any frontend library, so almost every problem already has a well-tested package, and hiring developers who know it is comparatively easy. It is only a view layer, though: routing, data fetching and rendering strategy are left to you or to a framework such as Next.js. For a mostly static, content-led website we would usually recommend Astro instead, and for teams that want strong conventions out of the box, Angular can be a better fit.
What we build with React

React questions
Is React good for SEO?
A React app rendered only in the browser can be harder for search engines to index. For search-sensitive pages we pair React with Next.js for server rendering or static generation.
Can React code be shared with a mobile app?
Business logic, types and some patterns can be shared with a React Native app, though interface components usually differ between web and mobile.
How do you keep a large React application fast?
We split code by route so users only download what they need, memoise expensive components carefully and keep state as close as possible to where it is used. We profile real interactions before optimising, so effort goes where users actually feel slowness.
Do you write React in TypeScript?
Yes, by default. Typed props and API responses catch a whole class of bugs before release and make the codebase far easier for another developer to pick up later.
How do you manage state in a React app?
We use server-state tools for data fetched from APIs and keep global client state small and deliberate. Heavy state libraries are only introduced when the application genuinely needs them.
How is a React application tested?
We write component tests that exercise behaviour the way a user would, plus end-to-end tests for critical journeys such as sign-up, checkout or data entry. Tests run automatically on every change in your repository.
Can React be added to an existing website gradually?
Yes. React can be mounted into individual parts of an existing page, so a legacy site can adopt it screen by screen rather than through a risky full rewrite.
Will other developers be able to maintain our React code?
React has one of the largest developer communities, which makes hiring straightforward. We follow common conventions, document architectural decisions and keep the code in your own repository so any competent React developer can continue the work.
How do you handle accessibility in React?
We use semantic HTML, proper labels and keyboard-friendly components, and check focus handling in modals, menus and forms. Automated accessibility checks run alongside manual testing with a keyboard and screen reader.
What drives the cost of a React project?
The number of distinct screens, the complexity of the data and business rules, integrations with other systems and the level of testing required matter most. A written requirements document lets us scope these properly before work starts.
