About:
Decker is an interactive multimedia sketchpad inspired by HyperCard. It provides a cross-platform environment for creating expressive interfaces, prototypes, and small applications using a stack of cards. The tool features a built-in scripting language called Lil for adding logic and interactivity.
Key Features:
  • HyperCard-inspired stack and card model
  • Integrated Lil scripting language
  • Cross-platform (macOS, Windows, Linux)
  • Supports drawing, widgets, and sound
Use Cases:
  • Rapid prototyping of user interfaces
  • Creating interactive multimedia art and demos
