Gluon is a Java-focused company and platform that co-leads the OpenJFX project and provides a suite of commercial and open-source tools for building cross-platform JavaFX applications. Their flagship open-source product, Scene Builder, is a drag-and-drop visual designer for FXML-based JavaFX UIs, enabling rapid interface design with clear separation between design and application logic. GluonFX extends JavaFX with additional components including a Rich Text Area, interactive Maps, and Emoji support. For mobile development, Gluon Mobile leverages GraalVM native image to compile JavaFX apps for iOS and Android from a single codebase. Gluon also provides JavaFX Long Term Support (LTS) contracts, commercial support for enterprises running JavaFX 11+, IDE plugins for IntelliJ IDEA, Eclipse, and NetBeans, and the GluonFX Maven/Gradle plugins that streamline the build and deployment pipeline. Gluon's deep involvement in the JavaFX ecosystem—from tooling to core contributions—makes it the go-to commercial partner for JavaFX-based enterprise, desktop, and mobile development.
