JavaFX LTS
JavaFX: Built by Gluon, Powered by You.
JavaFX is the backbone of modern, cross-platform Java UI development. As the leads of the OpenJFX project, we ensure the technology remains cutting-edge, secure, and available to everyone.
Philosophy
Open Source Sustainability.
Open Source Foundation. Enterprise-Grade Lifecycle.
OpenJFX is a robust, community-driven open-source project, and the latest mainline builds are always accessible to developers. However, mainline open-source development moves fast, focusing on the next upcoming release.
For enterprise production environments that require long-term stability, security compliance, and backported fixes on specific versions (such as JavaFX 17, 21 or 25) without the disruption of forced upgrades, Gluon provides commercial Long-Term Support (LTS) subscriptions. We bridge the gap between open-source innovation and corporate risk management.
Why subscribing matters.
Maintaining a world-class UI framework requires significant resources. When you subscribe to a Gluon LTS plan, you aren't just buying a support contract — you are ensuring that Gluon can continue to maintain JavaFX for the entire world.
Your subscription empowers us to:
- Perform the heavy lifting of framework engineering — security research, platform porting, and renderer optimization.
- Backport essential security fixes across all LTS versions and supported platforms.
- Ensure community users get JavaFX for free while subscribers get an enterprise-hardened, mission-ready platform.
