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 codeless 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 for spatially organizing your thoughts and making quick prototypes.

It's fun and look pretty. Exports to HTML and to a custom format.
