EraMC is a high-performance Minecraft network with a fully custom backend written in Kotlin. All game logic and database access runs directly on the server — kept fast and non-blocking through coroutines across the entire stack. gRPC and Ktor handle specific inter-service and API communication where needed. ClickHouse stores analytical event data, Grafana provides real-time infrastructure visibility, and the whole stack runs in Docker containers tied together via a private Tailscale mesh. All web-based frontend components are built with Next.js. We use GitHub Actions for CI/CD, with automated testing and deployment pipelines that keep our development process smooth and efficient. The result is a responsive, scalable Minecraft network that delivers a seamless gaming experience to players around the world.
