Launch GraphOS Studio

The Apollo GraphOS platform

Bring your supergraph from prototype to production

Apollo GraphOS is the platform for building, managing, and scaling a supergraph: a unified network of your organization's data, services, and capabilities—all composed into a single distributed API.

With one query to your supergraph's router, an application client can fetch data from any combination of sources:

Your infrastructure

Clients query your supergraph with a powerful language called GraphQL, which enables them to retrieve exactly the data they need, with no overfetching. The architecture of your supergraph is not exposed, and clients query it via a single, GraphOS-managed endpoint.

The supergraph is not a replacement for your existing infrastructure! Instead, it's a methodology for interconnecting your existing infrastructure, to make it more accessible and useful for everyone who interacts with your data.

What's in GraphOS?

The GraphOS platform provides an ever-growing collection of tools and services to help you build your supergraph and scale it safely alongside your organization.

These features are core to GraphOS:

  • Cloud routing.
    • GraphOS automatically provisions and hosts a router for each of your supergraphs. Clients query your router instead of individual subgraphs, which enables the router to automatically collect operation metrics that you can then visualize in Apollo Studio.
  • The schema registry.
    • GraphOS tracks the GraphQL schemas for all of your individual subgraphs, and it also handles composing those subgraph schemas into one supergraph schema for your router.
  • Safe schema delivery.
    • The schema checks feature of GraphOS enables you to verify whether proposed changes to a subgraph will cause an issue with other subgraphs, or with any of your existing clients.
    • Whenever you update a subgraph schema, GraphOS composes a new supergraph schema for your router. If composition succeeds, your router automatically begins using its new schema.
    • You can view the results of each launch that takes place whenever you update a subgraph schema, helping you resolve any issues that might occur.
  • An interface for every use case.
    • Apollo Studio is the primary web interface for GraphOS. Among other capabilities, you use Studio to create your organization and its supergraphs, view schemas and metrics, and test out operations in the Explorer.
    • The Rover CLI is the primary command-line interface for GraphOS. Among other capabilities, you use Rover to publish subgraph schemas to the registry, run schema checks from CI, and test out your supergraph within your development environment.
    • If you want to automate your own workflows outside of Studio or Rover, you can use the official GraphOS Platform API to do so. We'll expose more GraphOS capabilities through the Platform API over time.

To learn more about these and many more GraphOS features, see the complete GraphOS documentation.

What's in a supergraph?

If GraphOS is the platform for building and managing supergraphs, it's important to understand what's in a supergraph!

Every supergraph uses an open architecture called Apollo Federation, which consists of the following parts:

Your infrastructure
  • The router
    • The router serves as the client-accessible entry point to your supergraph. It receives all incoming queries.
    • As its name suggests, the router "routes" each incoming query to the appropriate combination of subgraphs (see the next item). It's also responsible for combining multiple subgraph responses into a single response for the client.
    • GraphOS takes care of provisioning and hosting your supergraph's router for you!
  • One or more subgraphs
    • Each subgraph is itself a GraphQL API that's responsible for a different subset of your supergraph's available data. Clients don't query your subgraphs directly! Only the router does.
    • Usually, each of your existing backend services acts as a different subgraph.
  • Backing data sources (databases, REST APIs, etc.)
    • Your subgraphs use these to populate data for incoming queries.

The diagram above shows a basic supergraph with a GraphOS-managed router, two subgraphs, and two corresponding data sources.

The following video provides a helpful visualization of how the Apollo Federation architecture helps organizations scale with their data:

What are the benefits of a supergraph?

Adopting a supergraph significantly improves the developer experience for every team (both internal and external) that interacts with your organization's data. These improvements enable developers to ship products and features more quickly, with greater confidence in their reliability and performance.

How do I implement a supergraph?

To implement a supergraph, you set up its individual parts: the graph router and your subgraphs. Apollo provides libraries and tools for setting up each part. And more importantly, we provide tutorials to help you!


  • If you're new to GraphQL, we recommend starting your supergraph journey with the Lift-off tutorial series.
    • Familiarizing yourself with fundamental GraphQL concepts is an important prerequisite to getting the most out of your supergraph.
  • If you're already using GraphQL, we recommend jumping in with your first GraphOS cloud supergraph. See the quickstart!

Implementing the router

If you create a cloud supergraph with GraphOS, Apollo provisions and hosts your supergraph's router for you!

For enterprise organizations that need to run their router in their own infrastructure, Apollo provides two libraries that can act as a router:

  • The Apollo Router (strongly recommended)
    • This is a high-performance binary written in Rust that adds minimal latency to request processing, even with extremely high traffic.
    • Because the Apollo Router is a precompiled binary, you don't need to write any boilerplate code around it to deploy it to your backend. All it needs is a configuration file for any behavior you want to customize.
    • Cloud supergraph routers use the Apollo Router under the hood.
  • Apollo Server with @apollo/gateway
    • This is Apollo's open-source Node.js GraphQL server library, which you can configure to act as a supergraph gateway.

If you get started with one of these libraries and later decide to switch to the other, you can do so without making any changes to the rest of your supergraph.

Implementing subgraphs

Each subgraph is itself a GraphQL API. Therefore, it uses a GraphQL server library to handle queries forwarded along by your graph router.

To act as a subgraph, a GraphQL server library needs to support the Apollo Federation subgraph specification. Fortunately, many popular libraries do! See Federation-compatible subgraph implementations.

Feel free to use whichever server library best suits your organization. Different subgraphs can even use completely different libraries, which is helpful if your various backend services use different languages.

How do clients query my supergraph?

To client applications, your supergraph appears the same as any other GraphQL API. Therefore, they query it with the same client libraries!

Apollo provides GraphQL client libraries for the following platforms:

These are all customizable, open-source libraries with powerful caching and state management features. Client-side caching enables an application to locally replicate the parts of your supergraph that it cares about. The application can then query itself for data if it's already present, which dramatically improves performance by eliminating redundant network requests.
