The short version

  • Each has a real cost: Bevy rust only, so it assumes a language most game teams do not already use; Gravity Sketch free plan limited to 150MB cloud storage and 3 simultaneous users per room
  • They diverge on capability: Bevy covers Entity Component System, Gravity Sketch covers VR design.

Where each one falls short

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

Bevy

  • Rust only, so it assumes a language most game teams do not already use
  • No visual editor of the kind Unity or Godot provide, so scenes and logic are written in code
  • Built around ECS, which is a different mental model from the scene-graph engines most developers come from

Gravity Sketch

  • Free plan limited to 150MB cloud storage and 3 simultaneous users per room
  • File format support limited to OBJ and STL on free plan; other formats require paid plan
  • Evaluation tools (surface contours, viewpoints, section tool) not available on free tier
  • VR access requires Meta Quest, Steam, or web app; limited to specific platforms
  • Data localisation only available on Enterprise plan
