The short version

  • Each has a real cost: A-Frame requires WebXR-capable browser; not supported on older browsers or devices without WebXR implementation; Horizon Worlds free to download but its full multiplayer VR experience requires Meta Quest headset hardware; the iOS/mobile app is a companion rather than a substitute for the headset
  • They diverge on capability: A-Frame covers Declarative HTML, Horizon Worlds covers World building.
