React

React is the most widely used library for building web interfaces, and the ecosystem around it — TanStack Start, Next.js, TanStack Query, Tailwind — makes it a complete platform for products that need to feel fast and behave predictably. We build React applications with server-side rendering for SEO, careful state management, accessible components and a design system rather than a pile of one-off styles. And we are just as comfortable taking over an existing React code base as starting a new one.
