Our review
Pros
  • Bones, IK, meshes, skins, and constraints support detailed 2D rigs
  • Runtime libraries and integrations cover engines, frameworks, and web
  • Command-line export, atlases, and reusable skins support production workflows
  • Bone rigs, inverse kinematics, constraints, and mesh deformation
  • PSD rig importing, skins, spritesheet export, and video export
  • Web and portable editors with runtime APIs for game integration
Cons
  • There is no free plan
  • Essential excludes meshes and other advanced features
  • Enterprise uses annual billing with a base license plus per-user fees
  • The project and documentation are works in progress
  • Its ecosystem fit lacks verified integrations
  • Its focus is narrower than a full production pipeline
