I'm not sure many people use K to write crud applications in the way you're thinking.
Kdb+ is fully integrated K and a K-like query language running on an SSD array database built for array languages and stock/banking usage. Can you write a web app in it? Sure, but I doubt very many do and those that do probably just use K as the numerical engine and JS for everything else.
