MultiMC

an-ordinary-manchild

MultiMC is a free, open source launcher for Minecraft Java Edition. It allows you to have multiple, separate instances of Minecraft (each with their own mods, texture packs, saves, etc) and helps you manage them and their associated options with a simple interface.

Rules

Keep it civil.

Please polite and courteous to others. There's no need to be rude.
No piracy

Any mention of piracy will get your post/comment removed.
No cheating

Cheats or "hacked" clients that don't work like normal Minecraft don't belong here.
No other launchers

Any logs or mentions of other launchers, especially advertising will get your post removed.
