An advantage of the client is the ability to stretch the window to insane resolutions such as 3840x1080.

The Minecraft stand alone client is a downloadable offline client that was released on June 30, 2010 for Windows, Mac OS X and other systems that support Java, such as Linux. It will run any version of Minecraft from Infdev and later. The client is able to connect to servers as well. Client mods only work with the stand-alone client as they directly modify minecraft.jar, the executable of Minecraft. Before Beta 1.3, a new version of the client was released with new features including a changelog and links to Mojang staff Twitter accounts.

Client version 1.2.2 does not accept the command line arguments that previous versions accepted.

Client versions up to 1.1 accepted command line arguments to automatically login and optionally join a server. Format to login without joining a server:

java -cp Minecraft.jar net.minecraft.LauncherFrame username password

Format to login and join multiplayer server:

java -cp minecraft.jar net.minecraft.LauncherFrame username password serveraddress:portnumber

The launcher was updated with the release of 1.3.2, adding the ability to download and play a demo version of Minecraft.

The stand-alone client only requires an internet connection for the first time run and for automatic updates. After that the game can be played offline.
