The short version

  • Only Bevy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Spine limited to 2048 pixel maximum atlas size on one dimension due to Apple device constraints; Bevy rust only, so it assumes a language most game teams do not already use
  • They diverge on capability: Spine covers Skeletal animation, Bevy covers Entity Component System.

Where each one falls short

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

Spine

  • Limited to 2048 pixel maximum atlas size on one dimension due to Apple device constraints
  • Can constrain only up to 2 bones at the same time; more requires creating hierarchy of constraints
  • PNG metadata can significantly increase file size and cause editor freezes
  • Export artifacts may include black outlines and white glows with translucent pixels

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
