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

WebStorm

  • JetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal
  • If the subscription lapses, use of new versions stops; JetBrains grants a fallback license only for the last version used while the subscription was active, per its published buy page
