Building a VR game that runs in the browser is more accessible than ever. The WebXR Device API gives developers a standardized way to create immersive experiences that work across headsets — no app store approval required. Here are the best tools to get started.
A-Frame
A-Frame is the most beginner-friendly WebXR framework available. Built on top of HTML and Three.js, it lets you describe 3D scenes using familiar markup — if you know HTML, you can build in A-Frame. It has a large community, hundreds of components, and excellent documentation.
Best for: rapid prototyping, beginners, and projects where development speed matters more than peak performance. Check out aframe.io to get started in minutes.
Three.js
Three.js is the most widely used 3D library for the web. It gives you fine-grained control over every aspect of your scene and is the engine underneath A-Frame. If you need custom shaders, advanced rendering, or full control over the render loop, Three.js is the right call.
It has built-in WebXR support via its XRManager. Best for: developers comfortable with JavaScript who want power and flexibility. Docs at threejs.org.
Unity WebXR
Unity is the most popular game engine in the world, and thanks to De-Panther's WebXR Export package, you can build a full Unity game and deploy it as a WebXR experience in the browser.
This path gives you access to Unity's entire ecosystem — physics, animation, the Asset Store — while targeting the web. Best for: teams already familiar with Unity, or projects requiring complex game logic and assets.
Wonderland Engine
Wonderland Engine is built specifically for high-performance WebXR. Its WebAssembly-based runtime makes it significantly faster than JavaScript-based alternatives, and it comes with a desktop editor for visual scene building.
Best for: performance-critical games, teams that want a purpose-built WebXR editor, and projects targeting mobile VR where frame rate matters most.
Which Should You Choose?
Start with A-Frame if you're new to 3D or WebXR — you'll have something running in an hour. Move to Three.js when you need more control. Use Unity or Wonderland Engine when you're ready to build something production-grade.
Once you've built something you're proud of, submit it to VrWebGames and we'll feature it for thousands of players to discover.
