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.

Relay-runtime is a more popular choice for managing GraphQL data in the React ecosystem. It has been widely adopted and is actively maintained by the Facebook team. Ember-apollo-client, on the other hand, is specifically designed for use with the Ember framework and may have a smaller community and user base.

Integration with Frameworks

Ember-apollo-client is designed to seamlessly integrate with the Ember framework. It provides a set of convenient abstractions and utilities for working with Apollo GraphQL in an Ember application. Relay-runtime, on the other hand, is primarily built for React applications and integrates well with the React ecosystem.

Developer Experience

Both packages provide a good developer experience. Ember-apollo-client offers a high-level API that simplifies working with Apollo in Ember applications. It leverages the conventions of the Ember framework. Relay-runtime provides a comprehensive and efficient data management solution but may require a steeper learning curve due to its advanced features and concepts.


Relay-runtime is known for its advanced optimizer and compiler, which can significantly improve the performance of GraphQL queries. It performs static analysis at build time to create an optimized execution plan. Ember-apollo-client also provides performance optimizations but may not have the same level of optimization and tooling as Relay-runtime.

Community and Support

Relay-runtime benefits from strong community support and has been widely adopted by large-scale applications. It has extensive documentation and resources available for developers. Ember-apollo-client may have a smaller community and resources specifically tailored for Ember developers.

Flexibility and Customization

Relay-runtime provides a powerful and opinionated approach to managing GraphQL data. It offers advanced features like automatic persisted queries and batching. Ember-apollo-client, being built for the Ember framework, provides a more tailored and Ember-specific integration. It allows developers to take advantage of Ember's conventions and features for building GraphQL-powered applications.
