alt Hacker NewsThis reminds me of LiveCode[1] (aka Revolution and MetaCard) which I’ve used quite a bit about a decade ago. Was also inspired by HyperCard. Just checked their site again and it seems they’ve discontinued the open source version and have pivoted to an AI-assisted drag and drop UI builder.
I'm using LiveCode for a dozen personal applications (and for just the fun of coding; I'm a retired s/w engineer). It's no longer free, but I started with HyperCard and LiveCode is an excellent replacement, at least for me.
