Apollo GraphQL Platform

Apollo GraphQL is an API orchestration platform that enables organizations to build, manage, and scale unified data graphs powering AI agents, web applications, and mobile experiences. The platform centers on a federated architecture that allows multiple backend teams to independently define and maintain subgraphs, which are composed into a single supergraph accessible through one endpoint. This eliminates the need for backend-for-frontend layers and experience APIs, reducing technical debt while enabling frontend teams to fetch exactly the data they need in a single request. The cloud-hosted GraphOS platform provides a schema registry, automated composition validation, deployment management, and observability tools including query metrics, error tracking, and performance analytics. Apollo Connectors enable teams to declaratively connect REST APIs to the graph without writing resolvers, accelerating integration of existing services. Client libraries for JavaScript, iOS, and Android provide intelligent caching, optimistic UI updates, pagination, and real-time subscription support. The server runtime handles query parsing, validation, execution, and response formatting with production-grade reliability. Trusted by enterprises including Netflix, Expedia, The New York Times, PayPal, and Booking, the platform powers critical data infrastructure at massive scale. Solutions span AI-driven experiences, developer efficiency, customer experience enhancement, monolith-to-microservices modernization, and post-merger system integration, with tooling for every stage of the API lifecycle.
