React

Great framework, works super well with zustand.

React offers a component-based approach that allows for reusable code, making development faster and more maintainable. Compared to alternatives like Angular, React’s flexibility and ease of integration with other technologies make it a preferred choice for building scalable user interfaces.

I love React for its declarative, functional approach to building UIs. It makes complex interfaces predictable, easy to reason about and to test, letting me focus on what the UI should do, not how to manage it.

Used React for its flexibility, huge ecosystem and the fast developer experience. It lets me build new features quickly and scale as TrailersHub grows.

Fast, flexible, and widely supported for building interactive interfaces; easier than alternatives like Vue or Angular for our team.

React's component architecture is the irreplaceable foundation of our real-time UI—and it had to be React. Designing a tool streaming AI code analysis required a framework handling complex state, frequent re-renders, and seamless interactions without performance degradation. React emerged as the only mature choice. Virtual DOM ensures streaming responses render smoothly token-by-token without janky updates—critical for the conversational feel. Hooks revolutionized WebSocket handling via ActionCable, managing real-time streaming with clean code avoiding callback hell. Declarative components made complex UI states explicit and predictable, while unidirectional data flow eliminated state bugs. What sealed React's necessity: the ecosystem. @auth0/auth0-react provided authentication, @stripe/react-stripe-js handled payments, react-router-dom enabled navigation. Strong TypeScript support caught type errors at compile time—essential for paid SaaS where reliability is non-negotiable. React's community meant every challenge had documented solutions accelerating development. Alternatives lacked performance for real-time streaming (Vue's reactivity couldn't match React's virtual DOM for high-frequency updates), required TypeScript rewrites (Angular), or had immature ecosystems (Svelte, Solid). React 18's concurrent rendering future-proofs our application. Component reusability transformed workflow—shared components maintain consistency while remaining customizable. We needed React because building modern, real-time, TypeScript tools demands proven performance at scale, an ecosystem accelerating development, and patterns keeping complex state manageable. React made our real-time AI interface delightful to build and maintain.

Anything you need—maps, charts, tables, virtualization, auth—already has mature React libs and talent. Reusable UI blocks for cards, filters, comparators, map pins, etc. ship faster and stay consistent.

Shout-out to React: We built elevaitr on React, and the ecosystem is honestly unmatched. We needed state management, authentication context, PDF generation, theming—all the stuff. Instead of building from scratch, the library ecosystem meant we could integrate what we needed quickly without reinventing the wheel. Performance has been solid too—the component reusability meant we could build the landing page, dashboard, and application logger without duplicating code. But the real win for us? React plays incredibly well with Firebase. Our auth flow, real-time data syncing from Firestore, and state management just work together seamlessly. We didn't have to fight the framework to make it play nice with our backend. If you're building a SaaS and want something that's fast, has a mature ecosystem, and doesn't fight you on integrations, React is the move.

React gives Guide.MD the flexibility and speed needed to render 6.5M+ provider profiles smoothly. It keeps the UI fast, modular, and scalable for future features.

React allows us to build a fast, modular dashboard with reusable components and clean state management. Perfect for developer tools.

Why do you like this better than the alternatives? React’s component-based architecture makes it easy to build reusable and maintainable UI elements. Its virtual DOM ensures efficient rendering, and the vast ecosystem of libraries and tools simplifies development. Plus, React’s flexibility works great for both web and native apps through React Native.

React offers a vast ecosystem with countless libraries and tools that make building modern web applications faster and easier. Its vibrant community provides continuous support, innovation, and resources — ensuring developers are never alone on their journey.

A flexible and mature UI library with a huge ecosystem and community — ideal for building dynamic, reusable interface components.
