Closed source (and vibe-coded) software, especially for a language runtime, is a non-starter for many people including myself. But proprietary license is actually common in the APL and K family of languages. They are fascinating though, and plenty of free/open implemenations exist, for example: https://ktye.github.io/

the author of the site makes no secret that the website is vibecoded. You're unfairly extrapolating that the product itself is vibe-coded (hard to do unless he is a time-traveller). And you're missing the point of the unique advantages that L offers wrt computation on compressed data.
yup website is Claude Design for prototype. For the core ... AI has been less helpful than I hoped - I believe largely because array style languages have so little source in training? But where Claude was especially helpful (other than the web design w/ Claude Design for the prototype) was analyzing ASM output of functions and optimizing those (although it was hard to go ASM>C or ASM>rust). E.g. lots of small mistakes would have been missed by not having restrict/const in places. Claude was great at compile all functions, analyze ASM, suggest optimized ASM (and ASM2vec was helpful as well for finding any "similar" code paths that could be combined (e.g. var/dev/cov are just moments)

Fair enough. Without seeing the code itself, one can only judge the book by its cover. I'm interested, but maybe not quite the target audience.
give it a spin! download is ~500kb for mac. It is however targeting folks who come from that world - but K/Q are absolutely worth exploring!
Unfortunately the code itself is in a style of C many find difficult to read. I blame my upbringing. ATW open sourced examples and it was not really helpful. More recently others are doing a step by step in more standard C https://github.com/ardentsia-cgs/kparser/

Isn't that "more standard C" because it's written by Claude?

Arthur Whitney's C is everything but standard

Not sure how you're replying to me without looking at the link.

talking about the linked parser which is clearly claude's not arthur's
this page/site seems fascinated with Claude, to the point where it is an unnecessary distraction.
