Apollo GraphOS

Apollo GraphOS is the commercial platform from Apollo GraphQL for working with GraphQL at scale. The vendor presents it as an orchestration layer for the APIs used by AI agents, web apps and mobile apps, connecting GraphQL and REST APIs so many applications can draw on one shared graph.

Its core idea is federation: backend teams contribute to a unified, composable graph with a single definition of core entities and business logic, rather than creating a separate backend-for-frontend or experience API for every client. Apollo Connectors bring REST APIs into the graph declaratively, and the platform is also pitched for giving AI applications secured, dynamic access to data. The site includes interactive tutorials and customer stories. GraphOS is proprietary and vendor-hosted, with a free start, a contact-sales option and a pricing page. Apollo also publishes open-source GraphQL libraries separately.
