The short version

  • Only Stride 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; Stride free and open source under MIT license, editor and runtime fully open source with no commercial tier
  • They diverge on capability: Spine covers Mesh deformation, Stride covers 3D graphics rendering.
  • Prices and features above were last checked on 30 August 2026.

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

Stride

  • Free and open source under MIT license, editor and runtime fully open source with no commercial tier
