apollographql/router

Apollo Router is a configurable, high-performance routing runtime for Apollo Federation that serves as a gateway for federated GraphQL graphs.

Apollo Router solves the problem of efficiently routing requests across a federated GraphQL architecture where multiple subgraphs are composed into a single graph. It acts as the entry point that receives client queries, routes them to the appropriate subgraphs, and assembles the results. The tool is built in Rust to prioritize performance and handles the complexity of query planning and execution across distributed subgraph services.

Teams building federated GraphQL architectures should consider Apollo Router if they need a production-grade gateway with strong performance characteristics. It suits organizations that have already adopted Apollo Federation and want a dedicated routing layer rather than embedding federation logic in their application code. The tool is particularly relevant for teams operating multiple GraphQL subgraphs that need centralized request handling, composition, and execution.

The project shows active development with regular updates to core functionality and configuration options. Work spans both foundational improvements to the routing runtime and expansion of features for federation scenarios. The maintainers respond to issues and incorporate feedback from users operating federated graphs in production environments.
