GraphQL and REST API gateways both serve as intermediaries between clients and backend services, but they differ significantly in their approach and capabilities. REST gateways handle HTTP requests with fixed endpoints, leading to potential data over-fetching or under-fetching. In contrast, GraphQL gateways process complex queries through a single endpoint, facilitating efficient data aggregation and specific data requests. While REST gateways use straightforward caching mechanisms and basic security, GraphQL gateways require sophisticated caching, offer granular security controls, and support schema management directly in code. GraphQL gateways also unify multiple protocols and enhance developer experience, making them a future-proof choice for modern applications.
