The short version

  • Each has a real cost: libGDX libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain; Unity AR Foundation requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • They diverge on capability: libGDX covers Java language support, Unity AR Foundation covers Plane detection.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

libGDX

  • libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain
  • Publishing targets are limited to Windows, macOS, Linux including Raspberry Pi, Android, iOS and HTML5
  • libGDX is a community-maintained Apache 2.0 project with no vendor and no paid support tier
  • libGDX ships as a framework rather than an editor, so there is no visual scene editor included

Unity AR Foundation

  • Requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • Performance varies significantly by device, with battery drain and heat generation on mobile
  • Emulators cannot accurately test AR experiences due to missing camera and sensor data
  • No WebXR support for browser-based AR experiences
  • Occlusion features show lower performance at 25-40 FPS compared to other features at 40-60 FPS
  • Limited access to latest platform-specific features compared to native ARKit or ARCore

Unity AR Foundation: What platforms does AR Foundation support?

AR Foundation supports iOS (via ARKit), Android (via ARCore), visionOS, HoloLens 2 (via OpenXR), and Meta Quest (via OpenXR). Testing in the Unity Editor is available through XR Simulation.

Source
Unity AR Foundation: Do I need additional plugins to use AR Foundation?

Yes. AR Foundation is an abstraction layer and requires platform-specific plugins: ARCore XR Plugin for Android and ARKit XR Plugin for iOS. These plugins implement actual AR features using native SDKs.

Source
Unity AR Foundation: Can I test AR experiences in the Unity Editor?

AR Foundation supports XR Simulation in the Editor for early testing, but accurate AR testing requires real devices because emulators cannot replicate camera and sensor data accurately.

Source
Unity AR Foundation: Does AR Foundation support web-based AR?

No, AR Foundation does not support WebXR. Unity has stated there are no current plans to add WebXR support to AR Foundation. Web AR requires alternative solutions like 8th Wall.
