War of the APIs - REST vs GraphQL vs gRPC by Memi Lavi

Memi Lavi

Compare the strengths and weaknesses of REST, GraphQL, and gRPC APIs, exploring their suitability for complex queries, scalability, performance, and real-time data streams.

Key takeaways
  • REST API is the most popular API, but it’s not suitable for complex queries and has performance issues.
  • GraphQL is schema-based, flexible, and scalable, making it suitable for complex queries and large datasets.
  • gRPC is a binary-based protocol that provides high-performance and low-latency communication, making it suitable for real-time data streams.
  • REST API is not entity-oriented, while GraphQL and gRPC are.
  • GraphQL provides schema-based reasoning, making it easier to reason about the data.
  • gRPC provides multiple communication styles, including unary, client-streaming, and server-streaming.
  • GraphQL provides a subscription-based API, making it suitable for real-time data streams.
  • REST API is not designed for real-time data streams, while GraphQL and gRPC are.
  • GraphQL and gRPC provide better performance and scalability than REST API.
  • REST API is easier to implement, but GraphQL and gRPC require more effort to set up.
  • GraphQL and gRPC provide more flexibility in querying data, while REST API is more rigid.
