Where each one falls short

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

Origami Studio

  • It runs on macOS only, so a Windows or Linux designer cannot open a file at all and mixed teams cannot share source documents.
  • It is free because it is a by-product of Meta internal tooling, which means no support agreement, no service level and release gaps that have run for long periods without explanation.
  • The patch graph is real programming with a real learning curve, so the time from install to a useful prototype is measured in days rather than hours.
  • Handoff is weak; engineers get something to watch and imitate rather than a specification, so the effort is discarded once the design decision is made.
  • Documents are compatible with nothing else, so a prototype cannot be maintained alongside the design source and goes stale as soon as the design changes.

PaintTool SAI

  • Windows-only software with no native Mac or Linux version.
  • Only supports 32-bit operation, lacking modern 64-bit performance benefits.
  • Lacks the advanced brush engine customization and layer effects found in tools like Photoshop or Clip Studio Paint.
  • No cloud sync or mobile app, unlike many modern illustration tools.
