CraftTweaker is a Minecraft Java mod that lets modpacks and servers customize the game. You change recipes, script events, add commands and alter item properties. It ships for Fabric (1.17.1 to 1.21.1), NeoForge (1.20.2 to 1.21.1) and Forge (1.12.2 to 1.20.4).
Many modpacks lean on it to remove conflicting recipes or build a central theme. With addon mods it goes further, with new blocks, items and even custom trees in world generation. It is a tool for pack authors more than a feature players notice on their own.
Loaders and versions
- Fabric: 1.17.1 to 1.21.1, newest builds published in March 2026.
- NeoForge: 1.20.2 to 1.21.1, with the 1.21.1 build as the newest.
- Forge: 1.12.2 to 1.20.4. Builds differ by version, so match the file to your Minecraft version.
- Java Edition only. Bedrock cannot load it.
Dependencies
NeoForge builds need nothing else. On Fabric, the newest builds require Fabric API and Faux Custom Entity Data. Fabric builds for 1.18.2 to 1.19.2 also want Ingredient Extension API, and builds for 1.17.1 to 1.18.1 need Fabric API plus Ingredient Extension API but not Faux Custom Entity Data.
On Forge, builds for 1.14.4 to 1.18.2 require JEITweaker. Other Forge builds list no dependencies. Put every required .jar in the mods folder beside CraftTweaker, and follow the Forge and NeoForge install guide if you have not set up the loader yet.
Getting started
Documentation lives on the CraftTweaker wiki, and the creators run a Discord for questions. Bugs and feature requests go to the GitHub issue tracker. Expect a learning curve, since the mod does nothing until you write scripts.
