Bootique has very low startup time / memory use. Assembled apps are small. Only the dependencies you need are included.
Apps are made of explicit modules, managed at build time. App features don't activate on their own, you are always in control.
Bootique helps to integrate any third-party library or framework ... for any kind of apps: web, RESTful services, jobs, CLI tools, JavaFX GUI, etc.
Bootique brings POSIX CLI to Java. You'd link CLI switches with Bootique command objects. There's built in CLI help in every app.
