The Apollo Optics for Rails agent is now ready for production workloads, thanks to help from core members of the GraphQL and Ruby communities. This agent enables any app built with graphql-ruby to understand the behavior and performance of GraphQL queries, providing insights into data usage at the field level. By analyzing these insights, developers can optimize their API's performance and identify areas that are underutilized, ultimately improving their application's overall efficiency. The agent is available for free, and users can create an account on apollodata.com/optics to get started with instrumenting their app.
