packwiz

packwiz is a command line tool for creating Minecraft modpacks. Instead of managing JAR files directly, packwiz creates TOML metadata files which can be easily version-controlled and shared with git (see an example pack here). You can then export it to a CurseForge or Modrinth modpack, or use packwiz-installer for an auto-updating MultiMC instance.

packwiz is great for...

  • Distributing private modpacks for servers
  • Creating modpacks for CurseForge and Modrinth

packwiz is not so great for...

Features

  • Git-friendly TOML-based metadata format
  • MultiMC pack installer/updater, with support for optional mods and fast automatic updates - perfect for servers!
  • Pack distribution with HTTP servers, with a built in local server for testing
  • Easy installation and updating of multiple mods at once from CurseForge and Modrinth
  • Exporting to CurseForge and Modrinth packs
  • Importing from CurseForge packs
  • Server-only and Client-only mod handling
  • Creation of remote file metadata from JAR files for CurseForge mods

Installation

Prebuilt binaries are available from GitHub Actions - the UI is a bit terrible, but essentially select the top build, then download the artifact ZIP for your system at the bottom of the page.

Another option is to use nightly.link. Just go to the page, and download the artifact for your system.

To run the executable, first extract it, then add the folder where you extracted it to your PATH environment variable (see tutorial for Windows here) or move it to where you want to use it.

In future I will have a lot more installation options, but you can also compile from source:

  1. Install Go (1.24 or newer) from https://golang.org/dl/
  2. Run go install github.com/packwiz/packwiz@latest. Be patient, it has to download and compile dependencies as well!
