> You buy SaaS and you have to then login, share credit card info, and have your data stored in the cloud somewhere with godknows what security practices

I'm speaking more about fake SaaS "we have an app and we charge monthly for it and license it." Obviously, a tool with cloud-based storage and sharing will be a different beast.

But do you trust a vibe coded app to do cloud-based storage and sharing better than a company or an indie developer? If you need these functions (like sharing a todo list between two users), you have a lot more concerns than "does it boot".

To my mind, this is the huge bit that should not be overlooked.

So much infrastructure is there to support doing "it" in the Cloud, for all definitions of "it." If we can vibe-code bespoke one-offs to solve our problems, a lot of that Cloud interaction goes away... And that stuff is expensive and complicated.

Hypothetically, open source app stores (I'm counting apt here) address this, but then it's someone else's solution to my problem, which doesn't quite fit my problem perfectly.

This approach to software engineering could be what 3D printing is to tangible artifacts (and I mean that including the limits of 3D printing regarding tangible artifacts, but even still.)

Another way to look at this is that you're giving away all of your source code as context, and probably a lot of things you don't necessarily want to share, if you aren't using self-hosted models.

Especially with agents that slurp up files, have access to databases, etc. You're literally giving access to your computer, your network and your data to third parties and letting them run code.

Data privacy is a real concern, but any SaaS provider worth their salt is using Stripe or similar for payments, not rolling their own. That's not as good as not providing the info in the first place but that makes it much less likely that your CC info is going to turn up in an S3 bucket with bad permissions or something.

It also means your data is one unfortunate coffee spill on the laptop keyboard from being gone forever. Unless you are doing your own cloud backups of your data and syncing it somehow. Which now the vibe coded app is really starting to grow in requirements then. Most people want that just handled for them.

> That means my data never leaves my device

I mean, if you vibecoded it you don't actually know that, do you?
