By Mrmayman

A simple, fast and powerful Minecraft launcher.

Incredibly lightweight.

QuantumLauncher uses very little CPU and RAM.
It's designed to be fast and responsive so you can focus on what you love!

In fact, sometimes it's lighter than Task Manager itself!

Get. Set. Go!

A few clicks. That's all it takes to set up your ideal Minecraft install
Just create a new instance and hit play!

And if you want to make your experience unique, adding mods is a breeze!

Who said modding is hard?

From managing mod loaders,
to downloading mods from the built-in store,
to even packaging and sending mods to your friends...

...It's all here!

And so much more!

(It's open source too!)
