Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
ARKit
- iOS-only platform, not available for Android or other operating systems
- Location-based AR accuracy limited to 3-5 meters, insufficient for precise applications
- Cannot handle very fast motion capture
- Accuracy varies with lighting conditions and surface characteristics
- Requires iOS 11 or later and specific device hardware

Answered from the vendors’ own pages
Unity AR Foundation: Is Unity AR Foundation free?
Yes, AR Foundation is free and included with Unity. It is a package within the Unity engine, though you need a Unity license (available free for personal use with under $200K revenue).
SourceARKit: Is ARKit free to use?
Yes, ARKit is free to use. It is included in Apple's iOS SDK and requires only Xcode and a Mac to start building AR apps. There are no licensing fees or subscription costs.
SourceUnity 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.
SourceARKit: What iOS devices support ARKit?
ARKit is supported on iPhone 6s and later, iPad Pro models, and the latest iPad models. It requires iOS 11 or later. Apple Vision Pro also supports ARKit with enhanced capabilities through visionOS.
SourceUnity 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.
SourceARKit: Can ARKit work offline?
ARKit can function offline for tracking and scene understanding since these operations run locally on the device. However, multiplayer AR features and cloud-based object detection require internet connectivity.
SourceUnity 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.
SourceARKit: Does ARKit integrate with game engines?
Yes, ARKit integrates with Unity through the Unity ARKit Plugin and with Unreal Engine. Developers can also use it with Metal, SceneKit, and Apple's RealityKit framework.
SourceUnity 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.
SourceARKit: What are ARKit's limitations with location-based AR?
ARKit's location-based positioning has accuracy limitations. Image-based positioning is primarily useful in urban areas, and beacon-based navigation provides accuracy of 3-5 meters, which is insufficient for precise AR applications requiring 1-meter accuracy or better.
