Decker is a multimedia platform and sketchpad for creating and sharing interactive documents with sound, images, hypertext, and scripted behavior, inspired by HyperCard. It ships as a native C/SDL2 application, a single-file web app, and a standalone interpreter (Lilt) for its scripting language Lil.

Use cases

  • build interactive documents with images, sound, and hypertext
  • create HyperCard-style stacks and multimedia sketches
  • prototype small interactive apps or games with a simple scripting language
  • author and share self-contained HTML decks on the web
  • script general-purpose tasks with the Lil interpreter (Lilt)
  • learn programming through a retro creative computing environment

When to choose

  • you want a HyperCard-like multimedia authoring tool that runs natively or in a browser
  • you need shareable, self-contained interactive documents as a single HTML file
  • you want a small, approachable scripting language for creative projects
  • you enjoy retro/fantasy-console aesthetics like ditherpunk pixel art

When to avoid

  • you need production-grade app development with modern UI frameworks
  • you require high-performance multimedia or 3D graphics
  • you need deep OS integration or native platform APIs
  • you want a large ecosystem of libraries and package management
