Relay-runtime is a JavaScript library that provides a runtime for executing GraphQL queries. It is commonly used in combination with the Relay framework for building React applications. Relay-runtime allows developers to write GraphQL queries in a type-safe and efficient way, and handles the complexity of managing data fetching and caching. It includes features like automatic queries and mutations batching, data normalization, and persisted queries for optimizing network performance.

Both Apollo Angular and Relay Runtime are popular choices for GraphQL clients in the Angular ecosystem. Apollo Angular has a larger user base and is widely adopted in the community. However, Relay Runtime is gaining popularity and has a growing developer community.

Integration with Angular

Apollo Angular is specifically designed to integrate seamlessly with Angular applications and provides helpful features like Angular DI integration and built-in Angular directives. Relay Runtime, on the other hand, requires additional setup and configuration to work with Angular applications and may not have the same level of integration as Apollo Angular.

Client Features

Apollo Angular provides a comprehensive set of client-side features, including caching, client-side schema stitching, and seamless integration with state management libraries like NgRx. Relay Runtime focuses more on performance optimizations and GraphQL-specific features like batching and automatic persisted queries. The choice depends on the specific needs of your project.

Developer Experience

Both libraries provide solid developer experiences, but Apollo Angular has a more mature ecosystem and extensive documentation, making it easier for developers to get started and find resources. Relay Runtime, while growing, may have a smaller community and fewer resources available for troubleshooting and learning.

Community Support

Apollo Angular benefits from being part of the larger Apollo GraphQL ecosystem, which has a strong community and ongoing development. This ensures regular updates, bug fixes, and new features. Relay Runtime also has an active community, but it may have fewer resources and plugins available compared to Apollo Angular.


Relay Runtime has a reputation for its excellent performance optimizations, including advanced features like automatic persisted queries and fine-grained control over network requests. Apollo Angular also provides good performance, but Relay Runtime may provide better optimizations for larger-scale applications with complex data fetching requirements.
