Built for clean mod management
.quartz Packages
Quartz uses its own package format with manifest validation and support for multiple mod engines.
Install, Enable, Disable
Manage installed mods from one launcher with library, enabled, disabled, and runtime folders.
Geode Compatibility
Existing .geode mods can be wrapped into .quartz compatibility packages while Quartz-native grows.
Runtime Testing
Quartz can stage enabled mods and run runtime checks before public releases.
Quartz-native is the future
Quartz is being built as more than a frontend. The goal is a real standalone platform with Quartz-native mods, a runtime API, package validation, templates, and developer tools.
