The Cosmo Router (which you can find in the Cosmo monorepo) is an open source (Apache 2.0 license) alternative to the Apollo Gateway or Router. It is a HTTP server written in Golang that is the central entry point for your federated GraphQL architectures, and is responsible for routing queries to the correct microservice/subgraph, aggregating their responses, and sending it back to the client in one cohesive format. You can even customize it with pure Go code of your own.
With Cosmo’s Router, you also get Prometheus metrics — the battle-tested, open-source (Apache License) service monitoring system — and R.E.D metrics, meaning you have a full metrics stack for fine-grained insights into router traffic, the error/success rates or the average request/response times/sizes of specific operations, and in general, everything you need to identify bottlenecks and optimize the performance of your system.
The Cosmo Router is powered by graphql-go-tools, a highly mature and optimized GraphQL engine (MIT License) that is the fastest and most reliable implementation for Federation V1. The Cosmo Router builds on it with its own optimizations.

This approach offers a level of customizability similar to what xcaddy does for the Caddy server, eliminating the complexities associated with writing Rhai scripts to customize a precompiled binary, as is the case with the Apollo Router.
