GraphOS Cloud is a cloud-hosted platform that offers instant-on access to blazing-fast graph routing for any GraphQL API, integrated tools for rapid query development, collaboration, and schema design. It enables faster, more reliable, and more intelligent query execution by layering in support for directives like `@defer` and entity types. GraphOS Cloud has built-in support for Apollo Federation, allowing easy scaling across teams with subgraphs, and integrates with a delivery pipeline to prevent breaking changes when collaborating on a graph with multiple subgraphs and client apps. The platform is available as a free Serverless plan with 10 million operations per month, and users can pay as they go for additional operations.
