REST vs gRPC

  • Lesson 3 of 6
  • Mid-level
On This Lesson 4 topics

This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.

In this lesson

pick between them using four criteria.

Planned topics

  • Contract: REST commonly uses OpenAPI (optional); gRPC requires a .proto file and generates code.
  • Performance: gRPC uses binary Protocol Buffers over HTTP/2, usually smaller and faster; REST commonly sends JSON over HTTP/1.1 or HTTP/2.
  • Tooling: REST is easy to test with curl and browsers; gRPC needs special clients (grpcurl).
  • Browsers cannot call gRPC directly; they need gRPC-Web or a gateway.
  • Typical split: REST for public APIs, gRPC for internal service-to-service calls with strict contracts.
