Start on one tree in the void — modded skyblock's most polished progression.
Installs automatically · Live in under 30 seconds · No port forwarding
SkyFactory 4 is modded skyblock perfected: you start on a single tree over the void and bootstrap to automated everything, guided by one of the best achievement trees ever built. The constraint is the genius — every resource chain has to be earned from leaves and saplings.
It's an ideal server pack because progress is legible: anyone can look at the island and see exactly how far the group has climbed since last week.
One click — SkyFactory 4 installs itself from CurseForge with the right Forge build.
Everyone grabs SkyFactory 4 via the CurseForge app at the matching version.
Join, break leaves, hope for saplings. The achievement book is your roadmap from there.
6 GB is our honest sizing for SkyFactory 4. Start here — upgrading later is one click and your world comes with you.
6 GB is comfortable — skyblock worlds are tiny, but late-game automation (mob farms, item networks) carries a real tick cost.
Both work: the default map is a shared island, which is where the co-op magic is. Island-per-team is configurable through the pack's world settings if your group prefers competition.
As safe as any world, and cheaper to back up — our automatic daily backups plus one-click manual snapshots mean a griefed or glitched island rolls back in minutes.
Name it, pick a plan, and SkyFactory 4 installs itself. That is the whole setup.
