Software architecture as a city-building game. Every building is a real infrastructure concept, every glowing packet is a user request, and each placement moves capacity, latency, availability, operating cost and user satisfaction.

Traffic arrives in waves and the city either holds or it doesn't — add a cache and latency and database pressure visibly fall, skip a load balancer and the queue backs up in front of you. Missions set concrete targets, like sustaining a request rate under an error budget. An optional six-step guided first run explains telemetry, construction, routing and bottlenecks before the opening wave.

There are no accounts, API keys, ads or paid services: state is local-first, so the game opens and plays immediately. Built with Codex.
