Get Sea Craft

Pick the modpack for the easiest install, or the standalone mod if you build your own setup. Either way you need Minecraft Java Edition .

VERSION MINECRAFT NEOFORGE JAVA CLIENT + SERVER

Early access, version . Dawn Island, the first island, is playable from start to finish, but this is an early build: expect bugs and unfinished parts, which will be fixed in later versions. Back up your worlds. Singleplayer is the supported way to play; multiplayer has not been tested.

The download is not up yet. The first build is packed and goes up shortly. Join the Discord server to hear the moment it lands.

Mod	Version	What it does	Download

Install the modpack

Install a launcher: CurseForge, Modrinth App or Prism Launcher.
Open the Sea Craft modpack page from the buttons above and press Install. With the .zip, use the launcher's Import.
Give the game at least 4 GB of memory in the profile settings.
Press Play, then Singleplayer → Create New World. Sea Craft: East Blue is already selected.

Install by hand

Install Java if your launcher does not bring it.
Run the NeoForge installer and pick Install client.
Put the Sea Craft jar and the five library jars from the table into .minecraft/mods.
Start the launcher, choose the NeoForge profile and play.

Running a server

Same mods on both

Every player and the server need Sea Craft and the same five library mods, at the same versions.

East Blue world

A fresh server makes an East Blue world by default. To set it yourself use level-type=seacraft:east_blue in server.properties.

Chart it first

Operators can run /seacraft chart status and /seacraft chart verify to check that every island was generated and repaired.

Common questions

Can I use Sea Craft in my own modpack or on my server?

Does it work with Forge or Fabric?

No. Sea Craft runs on NeoForge for Minecraft only.

Can I add it to an existing world?

You can, but the islands only exist in a world made with the Sea Craft: East Blue world type. A new world is the way to play.

The game crashes on start. What now?

Check that every dependency matches the version in the table exactly, then share your logs/latest.log in the Discord's help channel.
