SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you correctly set up and operate a modded Minecraft server from a modpack/server pack zip, including the right Java version, launcher setup, core server.properties, performance tuning, firewall access, and safe automated backups.

Core Features & Use Cases

  • Modpack/server pack bootstrap: Downloads, inspects, and installs the pack using the included startup/install mechanisms.
