Platform Support

Four platforms and fifteen game versions, 1.21 through 26.2.

1.21   1.21.1   1.21.3   1.21.4   1.21.5   1.21.6   1.21.7   1.21.8
1.21.9   1.21.10   1.21.11   26.1   26.1.1   26.1.2   26.2

1.21.2 is deliberately absent. It was superseded within days of release and is not worth carrying.

Platform File pattern Coverage Dependency
Paper and Paper forks chunkcarts-<version>+bukkit.jar One jar covers all 15 versions none
Fabric chunkcarts-<version>+<mcver>-fabric.jar One jar per game version Fabric API, required
NeoForge chunkcarts-<version>+<mcver>-neoforge.jar One jar per game version none
Forge chunkcarts-<version>+<mcver>-forge.jar One jar per game version none

A full release is 46 jars: 45 loader jars (three loaders across fifteen versions) plus the single Paper jar.

Pick the jar for your exact game version

Every uploaded file supports exactly one game version, with the Paper jar as the only exception. Do not use a loader jar on a version it was not built for. The 1.21 jar calls APIs that no longer exist in 26.2 and would crash a 26.2 server.

Fabric API is a hard dependency

On Fabric, Fabric API is required, and Fabric Loader refuses the mod without it. On NeoForge, Forge and Paper there are no dependencies at all.

Paper, not Spigot

The Paper jar is for Paper and Paper forks such as Purpur. It is not a Spigot plugin.

It relies on Paper's asynchronous chunk loading, which Spigot does not have. On Spigot, every chunk boundary a cart crossed would stall the main thread. The mod refuses to run on Spigot rather than degrade silently, because a server that quietly stutters whenever a cart moves is worse than one that tells you the plugin will not load.

Java

  • Java 21 for the 1.21.x builds.
  • Java 25 for the 26.x builds. 26.1 and later require it.

Clients

Server side only. Clients do not need it, do not benefit from it, and can join a server running it without having it installed. See the FAQ.
