How to Host a SkyFactory 3 Server

Hosting SkyFactory 3 cleanly is less about some hidden command and more about doing the obvious things in the right order: enough RAM for the automation systems that grow over time, a proper modpack flow, a clean first boot and backups before anything risky.

1

Start with 6 GB unless this is a very small server — enough breathing room for the garbage collector once islands fill with Ender IO machines and Refined Storage.

2

Use a proper modpack import flow instead of guessing from a client export.

3

Watch the first boot logs until the server finishes loading and the skyblock starter island generates.

4

Invite players only after the first clean startup.

5

Take a backup before world imports, Forge updates or config changes — skyblock progression is slow to rebuild from scratch.

CoalHost is built around modpack hosting, which makes SkyFactory 3 much less annoying to launch correctly.
