Sculk
Sculk is a Fabric technology mod that brings a programming language for Minecraft datapacks into the game, aimed at players who want to write logic without leaving the world.
What it does
The mod adds a programming language for writing Minecraft datapacks inside the game. Its code is written in a text form and compiled into the commands and functions that datapacks run, so logic can be built and reused across a world. Sculk requires Fabric API, which must be installed next to it on every side that runs the mod.
Installation covers client and server, so the server and every player need the mod. Its files target 1.20.4 only, with the latest Fabric build 0.0.5 released on 2024-03-08 on the beta channel. The mod is open source under the Apache License 2.0 and has public source code, an issue tracker and a wiki.
Sculk is listed alongside related projects such as Code Copper, Lua Datapack and Computer Craft Tweaked, which take a similar approach to scripting. The Technology category includes 747 mods with Fabric files for 1.20.4, so Sculk sits within a large group of game-logic tools.

How it compares
Yet Another Cobblestone Generator is a Fabric mod for 1.18.2 – 1.21.1 that is open source under the MIT License and runs on client and server, so it covers a different task than Sculk. ClusterComputers is open source under the GNU Lesser General Public License v3.0 only, with Fabric and Forge files for 1.20.1, and it adds in-game computers, so it targets a different kind of programming. Vanillaplus Ultimate is server-side only and open source under the MIT License for 1.20.1 – 1.20.4, so players can join without installing it.
