- AZ Launcher, - Pactify Launcher, - Badlion Client, - FTB Launcher, - MultiMC - T-Launcher... Go to their forums and tell them "It's not legal !".

Hmm. Thanks, but I make my own launcher if I want.

Hey ! I don't know if my post is in the right topic theme, but I really need your help... I've made a custom MC Launcher, and when I'm trying to launch the game, I've an error.
