What it does

Kyoyu is a utility mod that lets schematic files in the .litematic format be shared between players who connect to the same server. It is inspired by Syncmatica and works with the Forgematica port of Litematica on Forge and NeoForge, along with legacy Litematica and Ornithe setups. Builds exist for Fabric, Forge and NeoForge, and a version is also offered for Paper server platforms.

Installation means placing the Kyoyu file in the mods folder next to its dependencies. Kyoyu depends on Architectury, Loom and Litematica support mods, and the schematic sharing features only work when the relevant client mods are present. Either side can run it, and neither needs it: a player can join a server that runs Kyoyu without having it installed, and a vanilla client can join a server with Kyoyu, though it then cannot use the mod's features. Released under the GNU Lesser General Public License v3.0 only, the code is open source and public links exist for the source and the issue tracker. Files target 1.14 – 1.21.4 across 36 release versions.

Key features

Schematic sharing on servers
Players on the same server can share .litematic schematics with each other through the server.
Litematica addon compatibility
Schematics can be shared when Litematica runs through its Forgematica port, and legacy setups can take part as well.
Syncmatica-style sharing
The sharing approach follows the idea behind Syncmatica, so players exchange schematics without separate file transfers.

How it compares

Full comparison

Syncmatica is a Fabric and Quilt mod with a client and server environment, under the CC0 1.0 Universal license, covering 1.16 – 26.3. Forgematica is a client-side only mod for Forge and NeoForge, released under the GNU Lesser General Public License v3.0 only, for 1.16.4 – 26.2. Kyoyu is open source like both, but it works on either side and neither side needs it, and it targets Fabric, Forge and NeoForge.

Questions

Does Kyoyu need to be installed on every player's client?

No. Either side can run it, and neither needs it, so a player can join a server that runs Kyoyu without installing it, but the sharing features then stay unavailable on that client.

Which dependencies does Kyoyu require?

Kyoyu depends on Architectury and Loom, and it needs the Litematica support mods, such as malilib and Litematica, in the Mods folder for the sharing features to work.
