I miss HyperCard and I love projects like this at a nostalgia level - but if you're going to have aspirations that this is useful today (2026) with a real project then its a complete waste of time.
I want HyperCard where I can build out a stack or whatever and actually present it to people as a real and tangible thing. I love living in the past as much as anyone else, but this is a little disappointing.
If you want the "agentic future" version of this (sorry), tldraw just relased "tldraw offline"[1] which in some ways has a lot of overlap with HyperCard as well.
awesome, already love the detailed feature set. one thing I'd love is the option to change themes. for eg. i'd like a more modern theme if i want to create a presentation and send it across. retro is a bit of a cognitive overload on users who are now habitual of navigating a different type of UI.
Decker is neat. I was in the process of using it the other day, but discovered it did not have much by way of font size adjustment in text fields. You could make a heading, but I didn't see a way to make it bigger or larger than simply being a heading.
Decker fonts are composed of fixed-size bitmaps. The included example "fonts.deck" has a variety of additional fonts to choose from in various sizes, and an editor:
Decker prefers integral upscaling. On most browsers, "Decker -> Fullscreen" in the menu (or "app.fullscreen:1" from a script) will enable "stretching", but this feature is not supported by Safari on iPhones last time I tested.

We also recently gained a library for working with vector-based text:
