It's an easy to use mod launcher that handles mods for lots of other games, so you may already be using it. If you just want to play some of the best modpacks on this list, or quickly join a server that's using one, the CurseForge launcher will let you do so.

It's also an umbrella launcher that gives you easy access to installing modpacks from CurseForge, Feed The Beast, Technic, and more. You can keep different groups of mods separate from one another, for instance, if you have a few different configurations you enjoy playing. For the best level of control over your Minecraft mods and instances, MultiMC is the way to go.
