We replaced REST endpoints with gRPC in a latency-sensitive service.
Metrics: - Median latency: 45ms → 20ms - Payload size dropped by ~70% - Auto-generated client libraries boosted DX
But: - gRPC-web still lacks maturity - Debugging gRPC isn’t as easy as curl-ing a REST endpoint
Tradeoffs, always. But the gains were measurable.
