OpenJavaLauncher

Open-source java minecraft launcher (pro)

Launcher for (linuxoids) those who just want to run minecraft, and not download the launcher for 100 years

Help me with the GUI

I don't know how to make beautiful graphical interfaces. If you want to help, make a fork and pullrequest

NO PIRACY

The launcher does not have an online account login system, but this does not mean that you need to use it.

I FORBID YOU TO RUN MINECRAFT THROUGH IT UNLESS YOU HAVE PURCHASED AN OFFICIAL LICENSE FOR THE GAME!

My license - NameMC: FazziCLAY
