Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior. It draws strong influence from HyperCard, as well as more modern "no-code" or "low-code" creative tools like Twine and Bitsy. If Jupyter Notebooks are a digital lab notebook, think of Decker as a stack of sticky notes.

You can try Decker in your browser right now!

Decker can be used for making:

  • Presentations
  • E-Zines
  • Choose-your-own adventures
  • Visual novels
  • Calculators
  • Personal databases
  • Sound boards
  • Prototypes
  • Point-and-click games
  • And much more!

Decks are made up of a series of "cards" that you can draw on:

You can add buttons and other widgets to cards to make them interactive:

Or even build entire applications:

Decker provides a scripting language called Lil, which is easy to learn but highly expressive. Simple things are easy, and complex things are possible.

Decker understands tabular data. You can use  Lil to perform SQL-like queries on tables and import or export CSV files:

Source code for Decker is available on GitHub, and the latest documentation is available here. Decker will always be free and open-source. If you enjoy using Decker, please tell other people about it!
