Yep, no one builds anything in the kingdom of AWS

AWS is more like a commodity service, relatively easily swapped for something else.

… if you only run a few (micro)services on a few dozen machines.

Whole enterprises run everything in the cloud. 1000s of vms. From active directory, dns, virtual desktops until “lift and shift” legacy apps. And also a lot of networking to make the company networkwork with aws…

And that is only the technical aspect of it.

Migrations take years.

The result was created with just 4 conversations. I can't help but say it's amazing. https://claude.ai/public/artifacts/3cebb65f-a869-4dd8-9a89-6...

Is it? It just seems like a really small frontend to chat directly with Claude with limited yes/no/maybe options. And in true non-determinstic fashion, it will even ask you questions that can't be answered with yes or no, which completely ruins the game. Likely because it's just Claude with a couple sentences of a system prompt.

We were saturated with low effort wrappers like this years ago, I don't see how this is a game changer. Akinator worked better than this in 2008.

here we have a glowing example of humans not injecting their baggage into every conversation

Not supporting White Supremacy and Holocaust denial is "baggage"? I'd hate to know what kind of baggage you're carrying around.

There are loads of things I don't support, mostly I don't bring them up in unrelated conversations.

This is starting to encroach on Lovable, right? I do suspect the effect of these "vibe coded" apps on the SaaS market will be smaller than expected. Heavier-featured apps will have all sorts of functionality and polish a user won't even think to ask Claude to build. And the amount of effort to describe everything you need an app to do is higher than it seems. Instead, I think this is going to open a new paradigm with…

Yes and it may open the door for new platforms with pure backend (BaaS) focus. With AI hallucinations, letting AI write backend code is not feasible due to security implications. Access controls still require a control panel which can be easily audited. The frontend, however, is a completely different story. It reminds me of a saying from one of my ex-colleagues "Frontend development is like building a house of cards…

i think it is the opposite. Users don't care about the backend, so as long as security is fine and DB queries are not too bad, it will be okay. You still need somebody oversee it, but the endpoints can be generated easily.

Any UI client, though, needs to look authentic or people will hate it. Maybe generic stuff like dashboards or internal tools is fine, but any premium product needs to have good looking front, and that is really tricky.

if you hire someone are they going to always be right the first time you give them directions?

I used to love to make silly websites or apps with new technologies. Been doing it since flash. I have a pretty decent hit rate! It’s not unusually to get half a million or so people try one of them. But with AI that model is just totally broken because the running cost is so high. If I have half a million people come play my silly AI game that I have no wish to monetise - I am gonna be POOR very fast. Log in with [i…

>> If I have half a million people come play my silly AI game that I have no wish to monetise - I am gonna be POOR very fast. But the article says: When someone uses your Claude-powered app: They authenticate with their existing Claude account Their API usage counts against their subscription, not yours You pay nothing for their usage No one needs to manage API keys So how would that impact you?

That’s exactly my point, like now it wouldn’t, previously it would.

Actually implementing persistent storage for simple apps isn't that hard, especially for a big corp. Personally, I was using LLMs coding capabilities to create custom single-file HTML apps, that would work offline with localStorage. It's not that there aren't good options out there, but you can't really customize them to work exactly how you want. Also it takes like half an hours to get what you want. The only downsi…

Which tools did you make?

At first, I created a simple API via Python that was basically mimicking the localStorage API. It would accept getItem and setItem requests and write it to a file. In the HTML file I was replacing localstorage calls to calls to the API automatically, via a script that was doing a simple search-and-replace on the file. I was also assigning a custom subdomains via nginx to each html file, so that it could have the max 10MB storage that localstorage can have.

After a while it became clunky doing things with separate scripts, so I ended up creating - htmlsync.io. It's still pre-alpha, but registrations for the free tier are open.

Not if you use the managed services which is a very alluring proposition for most businesses.

We've learned this the hard way working with AI models, yelling at the models just doesn't work:) I would think someone working for Anthropic would be quite aware of this too. Either fix the prompt until it behaves consistently, or add conventional logic to ensure desired orchestration.

Totally agree. We’ve seen similar weirdness when trying to build deterministic behaviors around LLMs. It’s fun at first…. Until you’re debugging something that just needed a if/else. We’re now mixing prompts with conventional logic exactly for that reason, LLMs are powerful, but not magical.

If you're building full blown chat apps where that length limit matters using Claude Artifacts you should graduate to something less restrictive.
