Best When

You need a performant, self-hosted GraphQL federation gateway with extension-based customization and potentially MCP integration.

Avoid When

You require guaranteed, well-specified API contracts for programmatic gateway management via OpenAPI/REST/SDKs without relying on external documentation.

Use Cases

  • Unifying Apollo Federation v2 microservices into a single GraphQL API
  • Federating multiple upstream data sources (GraphQL subgraphs, REST, gRPC, databases, queues) behind one schema
  • Custom authentication/authorization and request lifecycle logic via WebAssembly extensions
  • Exposing the GraphQL API as an MCP server for model-context workflows
  • Self-hosted, high-scale GraphQL gateway deployments (including air-gapped setups)

Not For

  • Teams that only need a simple single-schema GraphQL server (no federation requirements)
  • Scenarios requiring a fully managed gateway with no self-hosting responsibility (gateway is self-hosted even in hybrid mode)
  • Use cases where the absence of publicly verifiable REST/OpenAPI/SDK contracts for the gateway itself is a blocker

Authentication

Methods: JWT authentication (gateway feature) Organization access token for Grafbase Cloud hybrid mode (GRAFBASE_ACCESS_TOKEN)
OAuth: No Scopes: No

Auth details for the self-hosted gateway are described at a feature level (JWT, federated authorization, rate limiting/trusted documents), but fine-grained scope/permissions model is not specified in the provided README.

Pricing

Free tier: No
Requires CC: No

README describes self-hosted gateway and an enterprise/managed cloud option, but no concrete pricing tiers or limits are provided in the supplied content.

Known Gotchas

  • The README describes functionality at a high level, but it does not provide machine-consumable API specifications (OpenAPI) or explicit gateway HTTP error/response contracts for automated agent integration.
  • Hybrid mode relies on an organization access token; ensure proper secret handling for GRAFBASE_ACCESS_TOKEN.
