Apollo GraphOS is now generally available, enabling centralized authorization enforcement across any number of connected services in the graph. This eliminates the trade-off between flexibility and scalability in GraphQL APIs, allowing for durable, graph-native access control using directives such as `@requiresScopes` and `@authenticated`. With GraphOS, authz enforcement can be defined declaratively, optimizing query execution and improving defense-in-depth, while also eliminating unauthorized subqueries and deduplicating simultaneous subqueries. The feature is now available in preview for all customers on the GraphOS Enterprise plan running self-hosted instances of Apollo Router, and can be tried out for free for 28 days by non-enterprise customers.
