| Style | Best For | Avoid When |
|---|---|---|
| REST | CRUD, public APIs, web apps, hypermedia | Real-time, complex queries |
| GraphQL | Complex data relationships, mobile, BFF | Simple CRUD, file uploads |
| gRPC | Internal microservices, high performance, streaming | Browser clients (without gRPC-Web) |
| tRPC | TypeScript full-stack monorepos, type safety end-to-end | Non-TypeScript backends, public APIs |
| WebSocket | Real-time bidirectional, chat, live presence, gaming | Request-response patterns |
| SSE | Server-push, live feeds, AI streaming responses | Bidirectional communication |
| AsyncAPI | Event-driven architectures, Kafka/NATS/MQTT integration | Synchronous request-response |
