Create native Java(FX) apps for desktop, mobile and embedded

Gluon Substrate

Gluon Substrate is a tool that converts Java(FX) Client applications into native executables for desktop, mobile and embedded devices. It uses the GraalVM GraalVM native-image tool to compile the required Java bytecode into code that can be executed on the target system (e.g. your desktop, on iOS, on a Raspberry Pi).

Gluon Substrate deals with JavaFX resources (e.g. FXML, shader code,...) and with platform-specific Java and native code that is part of the JavaFX platform.

While Gluon Substrate has an API that allows direct access to it, it is recommended to use the Maven plugin which simply requires some configuration in the pom.xml file of your project. The plugin will then invoke the Substrate API which in turn will use GraalVM native-image to compile the Java code, and it will link the result with the required libraries and configuration into a native executable.

There are a number of samples available that show you how to get started with Gluon Substrate. We recommend using your favourite IDE to run those samples.
