Maybe because people focus on what's important rather than a fancy website? How many startups can't offer more than a fancy website. Warren Buffet, one of the greatest investors of all time has barely a website.

have you seen the website for the latest version of k? "barely a website" doesn't even begin to describe it https://k.nyc

do you mean a website for something that isn't even released yet? Ever heard of a placeholder?

Algol? Did you mean APL?

Yes, yes I did. As penance, I will post Whitney’s sudoku solver in k: x@&/x?/:/:(+;!9;/:x)

Why did I have to see this mysterious and intriguing code in the morning, now my brain won't rest until I learn what every symbol means and how it works. Thanks for sharing!

ah. cheeky.

Seems like the only point of comparison against a competitive k/q runtime is an MBP run? suggestive to be sure, but would be good to see some other machines, esp. an x86.

Seems wild that the much-lauded "reference engine" leaves ~2x perf improvements on the table.

yeah the site's clearly vibecoded and isn't opensource, but i also think this is a genuinely interesting design space and more people should be building in it. APL ( https://www.dyalog.com/ ), BQN ( https://mlochbaum.github.io/BQN/ ), J/Jd ( https://code.jsoftware.com/wiki/Jd/Overview ), Klong ( https://news.ycombinator.com/item?id=10586872 ), Kerf ( https://news.ycombinator.com/item?id=9782520 ), RayforceDB ( https:…

The bottom of the page states:

"Site by Claude. Runtime by hand"

I think that's completely acceptable.

I agree 100%! If anything, I would encourage the site owner to increase the font size on that message. There is no shame to be vibecoding simple websites in 2026. IMHO: It takes away nothing from project. Also, I really like the second part: "Runtime by hand." That's cool in 2026 in the era of AI slop.

First, this is an incredible achievement. I hope that the author(s) can monetize this project. I guess they can try to undercut kx.com's current insanely high subscription costs. Is that a goal? I ask because I cannot find the source code for the project, only downloadable compiled binaries. (No hate on that -- you are free to make lots of money from your hard work and apparent genius!)

Second, in my personal experience, most quants refer to the platform as "kdb+", which uses the languages q (directly), k (indirectly), and qSQL. Is there a reason why the website landing page does not mention kdb+? I assume this is intentional.

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 mistake…

    > 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 E.g. lots of small mistakes would have been missed by not having restrict/const in places.
This is very interesting. It would be worth a separate blog post. I'm sure it would trend well on HN!

I’d encourage running the master bench yourself! Super easy

Or on the database side of the house try the h2o.ai base that duckdb excels at

intentional. I consider kdb/kdb+ to be understood as the KX products - but L runs the same database style functionality (the qSQL is essentially just sugar atop the q/k code. Most of which is written in k [or C in L for a number of components])
