KataBench compiles and runs untrusted .NET code on real servers. This is the architecture that keeps every submission isolated, observable, and ready to scale. I do a complete walkthrough of the architecture and tech stack powering my new learning platform for .NET developers. I explain how the Astro marketing site, React application, and .NET backend fit together. You’ll see how PostgreSQL, Redis, and NATS support the core platform, and why the API and database currently share the same Hetzner server. The most important part is the code execution pipeline. Every submission is processed by a worker and executed inside an isolated, disposable sandbox. I also show how Headscale protects the private network, how Dokploy manages deployments and scaling, and how OpenTelemetry sends logs, metrics, and traces into Grafana, Loki, Tempo, and Prometheus.
