What is the modern-day equivalent to HyperCard?

HyperCard, for those unfamiliar, was an early Macintosh software offering that sought to make interactive application development accessible to non-technical users. It combined a flat-file database with a GUI. It used the skeuomorphic paradigm of "cards" in a stack to represent the visual state and the navigation flow within a user-defined app. Using the editor and Paint-like overlay tools, you could drag and drop different elements onto a card, and attach functionality to those by coding in HyperTalk with a "natural language"-like syntax.

Everything was live-edited. So when a user typed in a form that existed on a card, it was saved on the fly in the flat file representing that card or stack of cards. It can be considered an early hypermedia system, predating the web. You could also mix and match cards from different stacks to create new stacks, which seems like a powerful concept.

While I can kind of understand why HyperCard was phased out, I can't think of a modern equivalent that provides this similar, modular functionality. In fact, it seems like the web would be a natural home for such a concept, but I don't know of any mainstream examples. What do you think? What's the modern equivalent to HyperCard?
