For service-to-service APIs it's the de facto standard — contract-first schemas, generated clients/servers, streaming, deadlines, and interceptor-based middleware give polyglot fleets type safety and performance no JSON/HTTP framework matches; pairs naturally with grpc-gateway or ConnectRPC for external REST exposure.
Where gRPC-Go + Protocol Buffers falls short, per the models
- Claude Poor fit for public/browser-facing APIs without a gateway layer, and the protobuf toolchain plus codegen workflow adds friction small internal teams may not amortize.
