You have probably seen the term vibe coding floating around Twitter, Hacker News, and every startup newsletter this year. Developers are talking about it. VCs are asking about it. And if you are a founder trying to build a product, you are wondering whether it is something you should actually care about.
Let's break it down simply.
What Does Vibe Coding Actually Mean?
Vibe coding is a style of software development where you describe what you want in plain language and let an AI tool like Claude, Cursor, or Copilot write most of the code for you. Instead of thinking through every function and file structure manually, you describe the vibe of what you are trying to build and the AI fills in the blanks.
The term was popularized by Andrej Karpathy in early 2025. He described a workflow where he would tell the AI what he wanted, accept whatever it generated, and keep iterating until it worked. No deep code review. No line-by-line debugging. Just describe, generate, test, repeat.
Why Founders Are Excited About It
For non-technical founders, this sounds like a dream. You have a clear idea in your head. You just want someone, or something, to build it. Vibe coding promises exactly that.
And for small features, quick prototypes, or internal tools, it actually delivers. You can spin up a working UI, wire up a basic API, or build a landing page in hours instead of days. That kind of speed matters when you are trying to validate an idea without burning through your runway.
Where Vibe Coding Falls Apart
The problems start when you try to build something real on top of a vibe-coded foundation.
AI-generated code tends to be inconsistent. It might use different patterns in different parts of the app. It might skip error handling. It might create subtle security issues that are hard to spot unless you already know what to look for. And when something breaks in production, debugging AI-generated code is genuinely difficult if you do not understand what the code is doing.
The bigger the product gets, the more these problems compound. You end up with technical debt baked in from day one, and fixing it later costs more than building it right the first time.
So Should You Use It?
Yes, but with clear boundaries.
Vibe coding is useful for exploration. Use it to prototype, to test ideas, to move fast on low-stakes features. Use it when you need a quick demo to show investors or get feedback from users.
Do not use it as the foundation for a production-ready product. Real software that handles user data, payments, and complex workflows needs to be built with intention. That means understanding the architecture, reviewing the code, and making deliberate decisions about how things are structured.
The Honest Take
Vibe coding is a powerful tool in the right hands. A developer who knows what they are doing can use it to move twice as fast. A non-technical founder using it alone will likely build something that looks like it works until it breaks in a way that is expensive to fix.
The best approach is to combine the speed of AI tools with the judgment of experienced developers. That is exactly how we work at Cystall. We use modern AI tooling to build faster, but every line of code gets reviewed, every architecture decision gets thought through, and every product ships clean.
