Startup configuration

Most users never need to touch startup config. The panel runs the right command for your selected game automatically.

What we run

For vanilla Minecraft, the startup command is approximately:

java <generated-flags> -jar server.jar nogui

For modded servers (Forge, Fabric, NeoForge), we use the loader's recommended startup script.

For Satisfactory, the startup command runs /opt/gameserver/start.sh, which launches FactoryServer.sh on the assigned game port.

For Valheim, Factorio, Palworld, Terraria, Project Zomboid, and 7 Days To Die, the startup command runs /opt/gameserver/start.sh, which launches the dedicated server with the assigned public game port.

For Discord bot workloads, the startup command runs /opt/gameserver/start.sh. The starter script installs Node dependencies if needed, loads .env when present, and runs npm start unless you set BOT_COMMAND.

Changing Minecraft version

Version and loader selection happens when the server is created. Self-serve version switching is not exposed yet. If you need to move an existing world to a different Minecraft version or loader, open a support ticket so we can help you back up the server and avoid corrupting the world.

Advanced

If you need custom startup flags (heavy modded environments, profiling), open a support ticket. We don't expose raw startup-flag editing in the UI during beta — it's a footgun and we'd rather walk you through it.
