I’ve been seeing a lot of people proudly shipping “vibe-coded” websites lately…

And honestly, I get the appeal.

You describe what you want, AI generates the code, things go live fast. No deep engineering, no long dev cycles.

But the more I look at these projects, the more a pattern shows up:

They work… until they don’t.

Some common issues I keep noticing:

• Code that looks fine but breaks when traffic increases.

• No real structure for scaling or future updates.

• Security gaps no one thought about.

• Performance that drops the moment real users show up.

• And the biggest one → no one fully understands the codebase.

It feels like we’ve optimized for speed of creation, but ignored stability and ownership.

I’m not against AI-generated code. But I do think most people underestimate what happens after the first version goes live.

Curious how others here are thinking about this: Have you shipped something using vibe coding? How did it hold up later?
