Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
A-Frame
- No commercial support or SLA agreements documented
- No enterprise licensing options available
- Documentation and community support are primary resources
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
