Origami Studio

Origami Studio, developed by Facebook, is a free Mac-based tool for high-fidelity interactive UI designs and prototypes. It uses a patch-based system reminiscent of node programming, letting designers define animations, gestures, and logic. A live preview on iOS or Android devices helps validate user flows. Integration with Sketch or Figma allows easy import of design assets. Origami includes advanced features like physics-based transitions and real-time camera or sensor inputs. Though it targets experienced UX designers, it excels at producing fluid, code-like prototypes for mobile apps or AR experiences.
