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...
