  • They diverge on capability: Apollo GraphQL covers Apollo Connectors, Swagger/OpenAPI covers OpenAPI Specification.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Apollo GraphQL

  • Pricing beyond the Developer tier requires contacting sales, making cost comparison harder for mid-size teams.
  • Adopting GraphOS effectively requires buy-in to the GraphQL paradigm, which is a larger architectural shift than adding a REST gateway.
  • The free plan's 1-day data retention and 60 req/min self-hosted router limit make it unsuitable for production use.
  • Volume-based per-request pricing can become expensive at very high request volumes compared to flat-rate API gateways.

Swagger/OpenAPI

  • The OpenAPI Specification itself is licensed under Apache License 2.0 and free to use; SwaggerHub is a separate paid tool built on top of it
