What QWERTZ Launcher is

QWERTZ Launcher is a free Minecraft launcher for Linux, macOS, and Windows. It supports Vanilla, Forge, and Fabric, with a Qt6 graphical interface. Users can create separate instances for launching modpacks, and the launcher supports multiple mod loaders and Java runtime management. Its account manager accepts an unlimited number of Microsoft accounts, and Microsoft login is available. Offline accounts can be created, although downloading the game still requires a premium account. Users can choose when sessions refresh automatically. Windows users are directed to download the latest release, while the README directs users on other operating systems to download the source, install requirements with pip, and run main.py. The releases page lists QWERTZ Launcher 2.0 as the latest release. The public repository uses the AGPL-3.0 license, and the project states that it does not support piracy.
