The Supergraph Manifesto # Supergraph is an architecture framework that offers reference architectures, design guidelines/principles and an operating model to help multiple teams to collaborate on a self-serve platform for federated data access, API integration/composition or GraphQL APIs. An implementation artifact of the Supergraph architecture is called a supergraph (lowercase s). When a supergraph is built with a GraphQL federation stack, the engine is often called a gateway or a router and the subgraph connectors are often GraphQL services.
