React Query is a powerful and flexible data fetching library for React applications. It simplifies the management of remote data by providing hooks for fetching, caching, synchronizing, and updating data from various sources like REST APIs, GraphQL endpoints, and more. React Query offers features like automatic caching, background data fetching, pagination support, and query invalidation, making it easy to handle complex data requirements in a declarative way.
SWR is a lightweight React Hooks library for data fetching. It provides a simple and efficient way to fetch data, revalidate it, and cache the results in a smart way. SWR focuses on improving the user experience by automatically revalidating data when the component is re-rendered or when a specified interval has passed. It also offers built-in support for error handling, loading states, and deduplication of requests.

Popularity
Both React Query and SWR are popular libraries for data fetching and state management in React applications. React Query has gained significant popularity more recently and has a larger user base, while SWR has been around for longer and is also widely used.
Features
React Query provides a rich set of features out-of-the-box, including automatic retries, request caching, pagination, optimistic updates, and more. SWR, on the other hand, focuses on providing a simple and lightweight API, with features like caching, revalidation, and deduplication.
Performance
Both libraries aim to optimize performance for data fetching. React Query uses a modern approach by leveraging React's Suspense and concurrent mode, making it efficient in handling asynchronous operations and reducing unnecessary re-renders. SWR takes a lightweight approach and focuses on minimizing network requests and maximizing cache efficiency.
Integration
React Query seamlessly integrates with other data management libraries like Redux and MobX, providing flexibility and compatibility with existing codebases. SWR has a similar philosophy and can be used with other state management libraries but is designed to work particularly well with React's built-in Hooks API.
Developer Experience
React Query provides a comprehensive and well-documented API with great TypeScript support. It also offers a UI-agnostic approach, meaning it can be used with any UI library or framework. SWR has a simple and intuitive API that is easy to use and understand, but its TypeScript support is not as robust.
Community and Support
Both React Query and SWR have active communities and receive regular updates and improvements. React Query has a larger community and thus more extensive community support, while SWR has been around longer and has a more mature ecosystem with additional plugins and extensions.
