"Vibe coding" is the name that stuck for a very real thing: building software fast by feel, with an AI assistant, without sweating the details — you describe what you want, accept what comes back, run it, and keep going on momentum. I do it. It's genuinely powerful. It's also quietly dangerous in ways that don't show up until later. The skill isn't doing it or avoiding it — it's knowing exactly when it helps and when it hurts.
The story
I first felt the pull of vibe coding on a weekend prototype. I had an idea, opened an AI assistant, and just... talked to it. Describe a feature, get code, paste it, see it work, describe the next thing. Two hours later I had a working prototype that would normally have taken me a day. It felt like flying. No friction, no docs, no boilerplate — just idea to working software at the speed of conversation.
So naturally I tried bringing that same energy into a production codebase. That's where it bit me.
In the prototype, "looks like it works" was good enough — nobody depended on it, the data was fake, the blast radius was zero. In production, I accepted an AI-generated change that looked right, ran fine in my quick test, and shipped it. It had a subtle flaw in how it handled a concurrent update — the kind of thing that works perfectly with one user and corrupts data with a thousand. I hadn't read it carefully because I was in "vibe" mode, riding momentum. The bug took far longer to find and fix than the time vibe coding had saved me. The speed was an illusion; I'd just moved the cost downstream and added interest.
That's the whole lesson in one experience. Vibe coding doesn't remove the work of understanding your system. It just lets you skip it temporarily — and you always pay it back, with the worst timing.
When it helps
Prototypes and throwaway code. When the goal is to learn fast and the code won't survive, vibe coding is perfect. Speed is the only thing that matters, and correctness barely does.
Exploring the unknown. Trying a new library, a new API, a "would this even work" idea. Vibe coding lowers the cost of exploration to almost nothing, so you explore more.
The boring, well-understood parts. Boilerplate, scaffolding, a standard form, a config file. Low risk, well-trodden ground — let the momentum carry you.
Getting unstuck. Sometimes a flawed first draft is exactly what you need to break a blank-page freeze. Generate something, react to it, refine.
When it hurts
Production systems people depend on. The moment real users and real data are involved, "looks right" is not good enough, and the cost of a subtle bug dwarfs the time you saved.
Complex or novel logic. Concurrency, money, security, anything with sharp edges. AI is confidently wrong here often enough that accepting code you don't fully understand is reckless.
Anything you'll have to maintain. Vibe-coded code you don't understand becomes a liability the day something breaks and you have to debug code you never really read.
When you don't understand the output. This is the real line. If you can read the generated code, judge it, and would have approved it from a teammate — great, the AI just typed faster than you. If you're accepting it because you don't understand it, you've stopped engineering and started gambling.
Vibe coding is fine until the moment "I'll just trust it" replaces "I understand it." That sentence is the boundary between a productivity tool and a future incident.
Key lessons
Match the method to the stakes. Throwaway prototype? Vibe away. Production payment flow? Slow down and read every line.
Speed that creates debt isn't speed. If you're moving the cost downstream, you haven't saved time — you've borrowed it at a bad rate.
Understanding is non-negotiable for code that lasts. AI can write it; you still have to own it.
Use vibe coding to start, not to ship. It's a fantastic first draft and a terrible final answer for anything important.
Action steps
- Ask "what's the blast radius?" before you vibe. Throwaway and low-risk → go fast. Production and high-risk → engineer carefully.
- Set a rule: read everything that reaches production. No AI code merges that you couldn't have written and defended yourself.
- Vibe the prototype, then rewrite the parts that survive with full understanding before they go live.
- Notice your own mode. If you catch yourself accepting code because you don't understand it, stop — that's the danger signal.
- Save the energy you bank. Use the time vibe coding saves on the boring parts to think harder about the parts that actually matter.
Final thoughts
Vibe coding is one of the most fun and useful shifts AI brought to building software, and I'd never give it up. But it's a sharp tool. Used on the right surface — prototypes, exploration, the boring 80% — it's a superpower. Used on production systems you don't understand, it's a way to ship bugs faster than you can find them.
The engineers who'll thrive aren't the ones who refuse to vibe code, or the ones who only vibe code. They're the ones who know exactly which situation they're in — and switch deliberately.
