Relay Runtime is a JavaScript framework for building data-driven React applications. It provides a declarative and efficient way to fetch and manage data from a GraphQL server. Relay Runtime optimizes data fetching by batching and caching requests, reducing the number of network round trips and improving performance. It also offers features like pagination, optimistic updates, and error handling out of the box.
Urql is a lightweight and versatile GraphQL client for React applications. It offers a simple and intuitive API for fetching and managing GraphQL data, with built-in caching and support for server-side rendering. Urql focuses on performance and efficiency, providing features like automatic cache updates, query deduplication, and subscription support.

Fight!
Popularity
Both Relay Runtime and Urql are popular choices for managing GraphQL in React applications. Relay Runtime is developed by Facebook and has gained popularity within the React community. Urql, on the other hand, is a lightweight and flexible alternative that has also gained a significant following.
Architecture
Relay Runtime is a comprehensive GraphQL client that provides a full-featured solution for managing GraphQL data in React applications. It has a more opinionated architecture and enforces certain conventions. Urql, on the other hand, is a more lightweight and flexible GraphQL client that allows developers to have more control over the implementation details.
Developer Experience
Relay Runtime provides a powerful developer experience with features like automatic data fetching, caching, and optimizations. It has a strong focus on performance and provides tools for code generation. Urql also offers a good developer experience with a simpler API and flexible configuration options.
Integration
Relay Runtime is tightly integrated with the React ecosystem and provides seamless integration with React components. It has built-in support for features like pagination, mutations, and subscriptions. Urql, on the other hand, is more agnostic and can be used with any JavaScript framework, not just React.
Community and Support
Both Relay Runtime and Urql have active communities and provide good documentation. Relay Runtime benefits from being developed by Facebook and has a larger community and more resources available. Urql, although smaller in terms of community size, has an active and supportive community.
Learning Curve
Relay Runtime has a steeper learning curve due to its more opinionated architecture and additional concepts to learn. It requires understanding Relay-specific concepts like queries, fragments, and mutations. Urql, on the other hand, has a simpler API and a lower learning curve, making it easier to get started with.
