(I make WorldEdit, WorldGuard, and some other mods for Minecraft.)
What am I looking at?
This is a custom Minecraft launcher that allows you to one-click install mods, letting you enable and re-order them at any time. It is small and just as easy to use as the official launcher, and it's really clean.
So what's this about mods?
- Install both ModLoader and non-ModLoader mods easily, both the same way, by clicking "Install" and choosing the file.
- Never touch META-INF or minecraft.jar. Just click, select the mod .zip, and then install.
- You don't need a custom mod made for the launcher. The launcher tries to be smart and figures how the .zip is organized on its own.
Wait! There's more to it:
- Easily change Java RAM usage options and other game-related settings.
- Switch between multiple Minecraft accounts and remember their passwords.
- Switch between different configurations, each with different settings.
- Switch between different .jar files to run, each with different lists of mods.
- Quick to load, clean news display. Can be disabled anyway.
- Quickly connect to servers you use by right clicking the Play button*.
- Supports updating Minecraft, downloading only files that were updated.
- Having problems? Open the console and view error messages. It won't close if Minecraft dies.
- Supports digital signature verification for everything, making sure all the files you download with the launcher were not tampered with.
- More options to be found in the options dialog.
- Open source! Don't trust some Internet person giving you a launcher? Compile it yourself.
- FOR THE TIME BEING, please get "developer versions" from
- v3.1.5 - .EXE for
- v3.1.5 - .JAR for
- v3.1.5 - .APP coming soon for

NOTE: If the .exe gives you a virus warning, use the .jar. The .exe simply wraps around the .jar and that is considered suspicious by some particularly trigger happy anti-virus programs.
How do I install a mod?
Open the "Addons" window, click "Install...", and select the .zip or .jar that you have downloaded.
- This works for most mods, but if a mod doesn't work, please post about it here.
- You may need to still extract files to your Minecraft folder for some mods.
- Be sure to put mods that are depended on by others (like ModLoader) near the top of the list.
- If a mod uses an installer, try the version without an uninstaller.
- Mods are loaded on the classpath directly from the original .jar or .zip. All mod archive files are placed in addons/<jar name>/ within the Minecraft folder.
- For .zips where the .class files are placed in some sub-directory of the .zip, the files will be moved up (including any resources in adjacent folders) to be at root.
- Package sealing and package certificate checks have all been disabled.
- The launcher primarily works through a custom classloader that disables various class loading mechanics and uses some compatibility code to get ModLoader mods to load. This means that minecraft.jar is never modified.
- v3.1.1: Fixed some mod installation issues.
