  • Each has a real cost: Abstract the product appears to be gone. Its documentation path 404s, goabstract.com no longer resolves, and abstract.com now belongs to an unrelated venture capital firm; Principle macOS only with no Windows or Linux editor available
  • They diverge on capability: Abstract covers Version control, Principle covers Timeline-based animation.
  • 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.

Abstract

  • The product appears to be gone. Its documentation path 404s, goabstract.com no longer resolves, and abstract.com now belongs to an unrelated venture capital firm
  • Built around Sketch files, so it never covered teams that moved to Figma

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
