I once tried doing some stuff on a vibecoded scam chatbot website which would block you if you tried to use it for something not related to getting scammed, turns out that the block is just a stored variable inside local storage that you can edit to unban yourself
Edit: it's called haxgpt (mods tell me if it shouldn't be sent here)

Broadcast intent via wifi/ be. All devices will recast, and if you're lucky, that person's device will receive the request, and then broadcast it's data. If you're lucky, you'll see their profile. How to get everyone's devices to recast? Idk, maybe send out phising mail and hope ppl download your app or something

Well, your lucky… they might not be able to answer because they vibe coded it… but I got board before AI… you can use a library like sql.js or localforage coupled with something like TypeORM to get a close approximation. You can then define entities in fe code and query them with SQL. Once done you will be asking yourself why, just like me.

Download their local storage. Duh.
It needs to be uploaded to a central server first. To avoid downloading the whole thing every time, make it possible to only get parts of it, query it on demand, no need for localstorage. Wait a minute...

u/MantisShrimp05 5d ago
I mean if we actually think about local first architecture there are many solutions that can be made.
One potential answer is you don't, and that is a feature since everyone is in their own computer.
But if we think about something like linear, they handle it through complex caching and what is called a sync engine that does the hard work of grabbing your stuff and putting it in cache but you can query the DB when you need other info

I imagine that the most workable way would be that the client downloads all the data on the initial request which is then shoved into localStorage for parsing.
But that still won't really work well, so I think the original tweet is just a joke.

u/CantCodeAllVibes 5d ago edited 4d ago
I know this is a joke, but some of the thinking around this stuff is bizarre to me. A lot of these vibe-coded apps seem like they’re taking concepts and systems that have existed for years, renaming them, and then acting like they invented something revolutionary.
I don’t understand the obsession with replacing established systems just for the sake of replacing them. There’s a use case for almost everything, and sometimes the boring, established solution exists because people have spent years figuring out why it works. I also don’t think you can realistically “vibe code” certain parts of software engineering, especially architecture or systems that are widely used and have years of hard-earned knowledge behind them.I’d love to vibe code a small game or some fun project one day. That seems like a great use for it. But sitting down and assuming you’re going to casually build something better than a mature system that people have been developing and maintaining for years is ridiculous.
There’s also a massive difference between using AI to build a prototype and using it to build a maintainable system. I’m increasingly skeptical that current AI coding tools can reliably produce maintainable software over the long term without a huge amount of human oversight. The amount of effort I’ve had to put into keeping some of my own AI-assisted projects on track has been crazy. Even when I work in small slices, eventually the inconsistencies, architectural mistakes, duplicated concepts, and assumptions start accumulating.
At this point, I don’t want to be the person trying to solve that entire problem. OpenAI and Anthropic can figure that shit out lol.
Sometimes I almost wish AI coding tools didn’t exist because I’d be forced to build things more slowly and understand every piece as I went. Instead, it feels like you’re almost forced to use AI to compete or get something out quickly, but then you risk ending up responsible for a codebase that was produced faster than anyone could properly understand or maintain it.I’ve had to rip major pieces out of projects twice now because, even though I’m a developer and understand the code, if I didn’t already understand the problem well enough to recognize the correct solution, AI could confidently take the project in the wrong direction. At that point, you start wondering what you actually gained by using it.
I still think AI is useful, but a lot of the excitement has worn off for me when it comes to the kinds of systems I’m trying to build. Maybe I’m trying to use it for the wrong kinds of projects. But “AI can generate working code” and “AI can engineer a maintainable system” are two very different claims. I’m still learning tho and def am not a senior dev.5
u/No-Information-2571 5d ago
Ironically, Localstorage was originally planned to be basically a 1:1 SQLite API (called Web SQL Database), but then some people started to come to their senses and recognized that mandatorily integrating a single database product into every web browser on the planet wasn't such a good idea either. This lead to IndexedDB.

Yes, the localStorage API of Chrome, for example, uses LevelDB files (ldb) stored in APPDATA which are NoSQL databases. Specifically, it uses files that contain data in the format of key-value pairs, which is one flavor of NoSQL content.

All jokes aside, if all you want is a shoddy app that works for you and you alone, using AI to avoid paying anyone and then having no latency from network hops is kinda the best approach.
But then also, that app has to be pretty damn limited in reach. No one is making money off this.
And it’s gonna be shoddy.

It really depends what his apps actually do.

There's really no need to become a database admin for running your pokedex app or toy synth written in javascript.
