Astropolis Server Hosting

Astropolis is a questing space modpack for Minecraft 1.19.2, with over 180,000 downloads on CurseForge. You start stranded on a single asteroid with nothing, and the entire pack is a progression outward: technology first, then planets, then eventually a route back down to Earth.

It is the most current pack of the space-skyblock family. Where the older asteroid packs sit on 1.12.2, Astropolis was built on 1.19.2 Forge and uses a modern mod stack — Mekanism, Compact Machines, Cosmopolis, Essence and Geodeopolis among others — which makes it a noticeably smoother play than its ancestors.

The quest book is the pack. On an asteroid with no terrain to explore, quests are what tell you which machine to build next and what it unlocks, and the chain runs from bootstrapping raw materials out of nothing all the way to interplanetary travel.

Compact Machines is the mod that quietly defines the mid game. Space is the resource you never have enough of on an asteroid, and being able to push an entire factory inside a single block changes how a group builds. Expect most late-game infrastructure on a busy server to live inside compact machines rather than out on the rock.

Astropolis runs on Minecraft 1.19.2 with Forge. The latest release is Astropolis 2.2 from April 2024, and the pack has been stable since. Client and server must run the same pack version — a mismatch on a void-world pack tends to produce broken world generation rather than a clean rejection, so it is worth checking before anyone builds.

Astropolis is a modern Forge pack with heavy tech mods, so it needs more than the old 1.12.2 skyblocks. For two to four players, 6 GB is a sensible starting point. For a group of five or more with separate bases and Mekanism running around the clock, 8 GB is the number to plan for.

Compact Machines is worth calling out here: each one is its own loaded space, so a server with a dozen active compact machines is doing more work than the player count suggests. If tick times climb, the culprit is usually how many of those are running rather than the size of the heap.

• Create a Minecraft server on your plan and choose a location near your players.
• Open the mod installer, select Astropolis, and let it install the pack with its matching Forge build.
• Wait for the first start to finish so the void world and starting asteroid generate properly.
• Send everyone the same pack version from CurseForge before they join.
• Take a backup once the group has a working base — asteroid packs give you nothing to fall back on if something goes wrong.

Mekanism is the backbone of Astropolis' ore processing, and it behaves differently here than in an open-world pack: with no mining to fall back on, its multiplier chain is not a convenience, it is how you get enough material to progress at all. Building the ore-processing line properly early pays for itself several times over.

Reaching a new planet is a large shared investment. Servers work best when the group decides together which body to target and splits the work — one player on power, one on the ship, one on supplies — rather than everyone quietly building their own rocket to the same place.
