How to Host a Create: Superflat Survival Server
Create: Superflat Survival drops players onto a completely flat Forge 1.20.1 world with no caves, no ores, and no natural terrain to mine — every single resource has to come from Create machines, villager trading, or alternative generation methods. That makes it the most mechanically demanding Create pack in the catalog, unlike terrain-based Create packs such as Above and Beyond, Astral, or Perfect World where you can still dig for raw materials. Hosting it well means getting the automation-heavy server environment right from the first boot.
Start your plan at CoalHost's own recommended floor of 6 GB RAM for Create: Superflat Survival — Create's contraption and mixer rendering plus constant automation activity add real memory load even though there's no cave terrain to generate.
Import the modpack directly from Modrinth or CurseForge through a clean import flow instead of guessing settings from a client export — Create: Superflat Survival's Forge 1.20.1 mod list needs to match exactly or recipes and machine behavior will desync.
Watch the server logs through the full first boot: confirm Forge loads every Create module cleanly and the superflat world generates its starter structures before anyone connects, since a broken load here usually means a stuck or crashed server later.
Only invite players after that first startup completes cleanly — a Create pack that boots halfway can corrupt the superflat world's starting resources, and there's no terrain to fall back on if that happens.
Back up before importing a world, updating the Forge loader, or changing configs — because there's no ore or cave generation to regenerate from, losing the world means losing every automation line the group has built from nothing.

CoalHost is built around modpack hosting, which makes Create: Superflat Survival much less annoying to launch correctly.
