Well this is a good start, I tried searching for “Anti-inflammatory” and the app crashed. Likely that scaling is way out of proportion considering it’s here on HN , but do you have any load balancing or caching setup? Debouncing on the inputs?

Weird - sorry to hear that. It's working fine for me.

I get this search result https://www.recipeninja.ai/search?name=Anti-inflammatory

What browser are you using? Voice mode or typing?

I type "lasagne", hit enter, some things pop up and disappear before I can read them, and then I get a solid white screen. (in Firefox)

Hmm it seems like recipe generation might be broken on Firefox. I'll look into it - thanks! It's working in Chrome

Search is working fine, I just tried https://www.recipeninja.ai/search?name=lasagne

Impressive!

35 kLOC is quite a bit. I wonder how straightforward and maintainable this app ended up to be. This would require taking a look at the sources. While good Rails code tends to be very terse, frontend may be quite voluminous.

> I believe within a couple of months, when things like log tailing and automated testing and native version control get implemented

This sounds a bit too optimistic, especially around automated testing, but yes, eventually this all will be there.

> an extremely powerful tool for even non-technical people to write production-quality apps

But why would non-technical people would even think in terms of log tailing and version control, any more than they think about the gauge of wiring in their walls, or the kind of modulation their Wi-Fi device use? For really non-technical audience to make a good use of such tools, it won't just take the AI to be a competent coder. The AI should become a competent architect and a competent senior SWE to translate from the product management language to the software development language, without even surfacing it when not explicitly asked. It's going to be quite a bit of a challenge to make it work, and work about as reliably as with a human team.

Since I wrote the blog post, I actually added automated tests which Windsurf / Claude Code runs before committing any change. It saved me a lot of headaches when the LLM decided to make random logic changes for no reason.

(1) It's incorrect to assume that the content published on HN benefits only the VCs, and none of the other participants.

(2) This particular post is an interesting data point in the research of what the current crop of LLM-based tools is capable of. It reads a bit like a Windsurf ad; I would like more details on how the technical side of the development panned out, what were the problems and where, how were they overcome, etc.

(3) The parent comment reads as a somehow funny mix of socialist "anti-greed" agenda and frowning upon the fact of sharing knowledge and experience freely.
