AR/VR development has moved far beyond simple virtual reality demos. Today, developers are building VR games, mixed-reality applications, industrial training systems, healthcare simulations, education platforms, virtual collaboration tools, product visualization, and immersive marketing experiences.
Because of this, choosing an AR/VR development platform is an important architectural decision. The best platform depends on the target device, graphics requirements, programming skills, performance requirements, and whether the project needs AR, VR, or mixed reality.
Some of the strongest options today include Unity, Unreal Engine, Godot, WebXR, and native platform SDKs such as Meta's development ecosystem.
1. Unity
Unity is one of the most popular choices for AR/VR development, particularly when developers want cross-platform support and a large ecosystem.
Unity is commonly used for:
- VR games
- AR mobile applications
- Training simulations
- Educational applications
- Industrial visualization
- Mixed-reality experiences
- Mobile XR applications
One of Unity's biggest advantages is its development ecosystem. Developers can work primarily with C#, while using a large collection of packages, assets, plugins, and XR tools.
Unity is also a strong choice for Meta Quest development. Meta currently describes Unity as its most popular engine for Quest development and supports immersive VR and mixed-reality applications through its Unity ecosystem.
Best for: Cross-platform AR/VR, mobile XR, indie development, and teams that prefer C#.
2. Unreal Engine
If visual quality and advanced 3D rendering are major priorities, Unreal Engine is one of the strongest options.
Unreal supports AR, VR, and mixed-reality development and provides tools for head-mounted devices as well as handheld AR. It also supports OpenXR, which helps developers target compatible XR platforms using a common standard.
Unreal is particularly attractive for:
- High-end VR games
- Architectural visualization
- Automotive visualization
- Simulation
- Cinematic experiences
- Large 3D environments
- Enterprise training
Another advantage is that developers can use both C++ and Blueprints. This gives technical teams detailed programming control while allowing designers to build functionality visually.
Unreal also provides a dedicated VR Template containing common VR functionality such as teleport locomotion and interaction logic, which can significantly speed up prototyping.
Best for: High-quality 3D VR/MR, simulation, visualization, and demanding graphics.
3. Godot
Godot is an interesting choice for developers who prefer an open-source game engine.
Godot supports XR through OpenXR, providing a standardized approach for communicating with compatible XR platforms. Its documentation recommends the Mobile renderer for desktop VR and standalone headsets such as Meta Quest 3 because it is better optimized for those XR workloads than Forward+.
Godot can be attractive for:
- Indie developers
- Open-source projects
- Educational projects
- Smaller VR games
- Experimental XR applications
The main advantage is flexibility and the fact that developers can work with an open-source engine rather than depending entirely on a proprietary ecosystem.
Best for: Indie developers, open-source projects, and lightweight XR applications.
4. WebXR
Not every AR/VR application needs a traditional game engine.
WebXR allows developers to create immersive experiences that run through compatible web browsers. This can be particularly interesting for applications where users should be able to access an experience without installing a traditional native application.
For example:

WebXR

Compatible Browser

VR / AR Device
Developers can use web technologies and frameworks such as JavaScript, Three.js, A-Frame, or Babylon.js.
Meta's current developer documentation specifically supports WebXR for immersive experiences on Meta Quest Browser and describes Three.js, A-Frame, and Babylon.js as options for building immersive web experiences.
Best for: Browser-based XR, demonstrations, education, lightweight experiences, and applications that benefit from easy distribution.
5. Meta Horizon OS Development Platform
For developers specifically targeting Meta Quest and Horizon OS, Meta provides several development paths rather than forcing developers into a single engine.
Developers can use:
- Unity
- Unreal Engine
- Native C/C++ with OpenXR
- Meta Spatial SDK
- Android/Kotlin
- WebXR
Meta's current platform documentation explicitly lists these different paths depending on the type of application being built.
This is important because a VR game and a productivity application may have very different technical requirements.
For example, Meta's Meta XR SDKs for Unity provide functionality for interaction, locomotion, grabbing, hand interactions, and other XR capabilities.
Best for: Developers specifically targeting Meta Quest/Horizon OS.
6. OpenXR
OpenXR is slightly different from Unity or Unreal because it is not a complete game engine. It is an open standard for XR development.
Its importance is that developers can build against standardized XR interfaces rather than writing completely different implementations for every headset.
Unreal's current documentation describes OpenXR as a royalty-free, cross-platform standard for accessing XR platforms and devices. Meta has also recommended the OpenXR path for developers using Unity, Unreal, and Godot.
In practical terms:
XR Application

OpenXR

Headset A Headset B Headset C
This does not eliminate every platform-specific difference, but it can significantly reduce fragmentation.
Best for: Cross-platform XR development and teams that want to minimize platform-specific dependencies.
What Should You Consider Before Choosing?
Target Hardware
First decide whether you are targeting Meta Quest, Apple Vision Pro, Android AR, iOS AR, PC VR, or multiple platforms.
Performance
XR applications are particularly sensitive to performance. Low frame rates and poor latency can seriously affect the user experience and comfort.
Development Skills
If your team already knows C#, Unity may provide a faster development path. If the team is experienced with C++ and high-end 3D rendering, Unreal may be a better fit.
Device-Specific Features
Cross-platform standards are useful, but sometimes you need platform-specific capabilities such as advanced hand tracking, passthrough, spatial anchors, or scene understanding.
Distribution
A native application, browser-based WebXR experience, and enterprise application may require completely different deployment strategies.
Final Thoughts
For most teams, Unity and Unreal Engine are the two major starting points for serious AR/VR development. Unity is particularly attractive for cross-platform development, mobile XR, and teams comfortable with C#. Unreal is a strong choice when advanced graphics, realistic environments, and high-end 3D simulation are priorities.
Godot is worth considering for developers who value open-source technology, while WebXR is an excellent option when browser-based distribution is important. For Meta Quest-focused projects, developers can choose among Unity, Unreal, native OpenXR, Meta Spatial SDK, Android, and WebXR depending on the application.
The most important lesson is that choosing an AR/VR platform should not be based only on which engine has the most features. Consider the complete lifecycle:
Prototype → Device Testing → Interaction Design → Performance Optimization → Platform Integration → User Testing → Deployment.
In XR development, comfort and performance are just as important as visual quality. A technically impressive application that causes latency, poor tracking, or uncomfortable movement will still provide a poor user experience. That is why the best AR/VR platform is ultimately the one that allows your team to build the required experience reliably, efficiently, and at the performance level expected by the target device.
