The WunderGraph team is announcing Open Federation, an open-source specification for building federated GraphQL APIs without relying on proprietary technology. This initiative aims to enable the GraphQL ecosystem to build federated APIs in a more accessible and attractive way, leading to increased adoption of GraphQL and innovation in the industry. Open Federation builds upon Apollo Federation's directives, providing a more detailed and specific specification for composing subgraphs and resolving federated GraphQL queries. The project is a collaboration between multiple vendors, including WunderGraph, Grafbase, Escape Tech, Neo4j, TailorTech, Sibipro, Soundtrack Your Brand, Travelpasses, and others. Open Federation has the potential to replace Apollo Federation as the de facto standard for federated GraphQL APIs, offering a more open and flexible approach to API composition.
