Purpose: QuantumLauncher is an open-source Minecraft launcher with instance management and modding features.
Mod store: Its built-in store lets users browse and install mods, mod loaders, resource packs, shaders, and modpacks.
Instances: Instances isolate game versions so they do not clash.
Older versions: It supports older Minecraft versions through Omniarchive, including skin and sound fixes and rare versions.
Integrations: The mod store offers CurseForge and Modrinth backends.
Mod management: Users can manage mods and mod loaders in one place and package and share mod collections with friends.
Performance: The maker describes the launcher as using minimal CPU and RAM and being lighter than the vanilla launcher and common alternatives.
Offline mode: The launcher supports offline mode, which the maker says is at the user's own risk.
License: The launcher is licensed under GNU GPL v3, with some assets under additional licensing.
Support: The maker directs users with issues or complaints to open an issue in the GitHub repository.
Downloads: Stable downloads are offered for Windows, macOS, and Linux, including platform-specific builds and Linux package options.
macOS limitation: The FAQ says macOS may block the app because the maker cannot afford Apple's Developer ID fee and documents a terminal workaround.
