The tiniest step towards a future where AI eats all apps. No persistent storage and other limitations make it just a toy for now but we can imagine how people will just create their own Todo apps, gym logging apps and whatever other simple thing. no external API access currently but when that's available or app users can communicate with other app users, some virality is possible for people who make the best tiny app…

#52Earlier quoted context omitted.
There is coming a very_soon_time whereby one will have to ensure all the routes and failure_modes for the AIs plumbing are functional. What if the outage is specifically that AI_agent cant reach [thing]?
> What if the outage is specifically that AI_agent cant reach [thing]? We already saw some examples of this in Anthropic's safety papers - the AI will reach out to the human to get help with that - essentially using a human as an API/tool.

#53Is this the end of - or at least a significant challenge to - SaaS? Why buy into saas tooling if you can just slap something together - that you fully own - with something like this?

#54>They authenticate with their existing Claude account Only works if both app producer and user are in the Claude ecosystem
Seems like it's essentially the same model as OpenAI's Custom GPTs [0], but now with the custom code in front of the AI rather than behind it. [0] https://openai.com/index/introducing-gpts/

#55More of my notes here: https://simonwillison.net/2025/Jun/25/ai-powered-apps-with-c...
I'm amused that Anthropic turned "we added a window.claude.complete() function to Artifacts" into what looks like a major new product launch, but I can't say it's bad marketing for them to do that!
Re: Build and Host AI-Powered Apps with Claude – No Deployment Needed
#56I 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…
This is seriously lacking but I think things like jailbreaks and malicious prompts make it a bit too brittle for now
Also I reckon the cost of running a text chatbot is basically peanuts now (that is, for a giant tech company with piles of hard cash to burn to keep the server farm warm)

#57Instead, I think this is going to open a new paradigm with an immense long-tail of hyper-niche fit-for-purpose business applications. There's so much small-scale work that happens in corporations that isn't common enough to be worth building a product to solve. But it's still a big time-saving to the departments/users if they can improve the process with a vibe-coded app!
Re: Build and Host AI-Powered Apps with Claude – No Deployment Needed
#58This 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…
With a mass market product leader you’re sacrificing a bit of customization for long-term stability.

#59Is this much different from the custom GPTs that OpenAI pushed a year or two ago?
Re: Build and Host AI-Powered Apps with Claude – No Deployment Needed
#60I was too lazy to build a whole frontend like Lovable.
