gRPC vs. tRPC
Cross-Language Contracts vs. TypeScript End-to-End
Both eliminate the agony of out-of-sync REST clients. gRPC uses Protocol Buffers for cross-language compatibility. tRPC uses TypeScript inference for zero-compile synchronization.
📊 Scoring Matrix
Binary (Protobuf)
JSON
Excellent (Generates all langs)
None (TypeScript only)
Slow (Compile step required)
Instant (Inferred types)
Requires grpc-web proxy
Native via HTTP
High (HTTP/2 + Binary)
Standard HTTP/JSON
Steep
Non-existent (if you know TS)
📋 Executive Summary
tRPC is a superpower for full-stack TypeScript teams. gRPC is an absolute necessity for polyglot microservice architectures.
tRPC accelerates full-stack feature delivery by 20-30% by eliminating context switching and payload compilation steps.
