I built an open-source panel for self-hosting game servers

Why I built this

I wanted a self-hosted panel for managing Minecraft (and eventually other game) servers, with a modern stack — Node.js/TypeScript on the backend, React on the frontend, PostgreSQL + Prisma for storage. The panel and a lightweight node agent talk over WebSocket, so you can manage multiple machines from one place.

The result is Kretase — MIT licensed, fully open source.

What it does

• Web console, file manager, player/whitelist management


• Multi-node support (manage several machines from one panel)


• Live CPU/RAM/disk stats


• World manager: browse/install premade worlds via CurseForge, backup/download existing ones


• Plugin/mod manager built into the panel


• One-command install script for Ubuntu/Debian

Tech stack

• Backend: Node.js, TypeScript, Express, PostgreSQL, Prisma


• Frontend: React, Vite, Tailwind


• Node agent (wings): separate process per machine, communicates with the panel over WebSocket

Still actively developing this — feedback, issues, and contributions are all welcome. Happy to answer questions about the architecture in the comments.
