Where each one falls short

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

Principle

  • macOS only with no Windows or Linux editor available
  • No vector morphing capability for complex shape transformations
  • Limited asset creation tools; cannot create vectors or shapes directly within Principle
  • Sketch import flattens certain properties including paths, fills, borders, masks, blur effects, and text layers
  • Limited variable support, logical loops, and data input capabilities compared to tools like ProtoPie or Origami

RubyMine

  • No permanently free tier for commercial use; requires an ongoing subscription
  • More resource-intensive than lightweight editors such as Sublime Text
  • Focused primarily on Ruby, so polyglot teams may prefer IntelliJ IDEA Ultimate with plugins instead
  • Startup time can be slower than simpler text editors on older hardware
