Power of NestJS, More Throughput

Recommended reading: Moost without the ceremony — the framework architecture being benchmarked here. Performance claims from framework authors usually mean a hello-world endpoint. One route, no auth, no cookies — nothing like a real app. This benchmark tests the full HTTP lifecycle: 21 routes, cookie parsing (~20 cookies per request), auth guards, body parsing, error responses — all through each framework's DI layer. Traffic is weighted to match real SaaS patterns. Full source: prostojs/router-benchmark .
