What Is Vibe Coding? A Honest Beginner's Guide

Everyone’s talking about vibe coding. Your LinkedIn feed is full of people showing off apps they built in an afternoon. Developers on X are arguing about whether it counts as ‘real’ coding. And if you’re new to AI, you’re probably wondering what vibe coding actually means and whether you should care.

You should. But not for the reasons most people think.

Vibe coding is one of those terms that sounds more complicated than it is. At its core, it means building software by describing what you want in plain language and letting AI write the code for you. You talk. The AI builds. You test it, give feedback, and repeat until it works.

That’s it. No programming languages to learn. No syntax to memorise. Just a conversation.

Where the Term Came From

AI researcher Andrej Karpathy coined the term in February 2025 in a post on X. He described it as a way of coding where you ‘fully give in to the vibes, embrace exponentials, and forget that the code even exists.’

Karpathy wasn’t being entirely serious. He was talking about throwaway weekend projects, not production software. He admitted he didn’t read the code, didn’t review the changes, and just hit ‘Accept All’ until things worked.

But the term stuck. Within weeks, vibe coding had its own Wikipedia page. Collins English Dictionary named it their Word of the Year for 2025. And an entire industry of tools sprang up around the idea that anyone could build an app without writing a single line of code.

How Vibe Coding Actually Works

The process is simpler than most articles make it sound. You open a tool (more on those in a moment), describe what you want to build in everyday language, and the AI generates the code.

Here’s the loop:

You describe your idea. Something like ‘Build me a simple website that tracks how many books I’ve read this year.’ The AI produces the code. You run it and see what happens. If something is wrong or missing, you tell the AI: ‘Add a button that lets me mark a book as finished.’ It updates the code. You keep going until the thing does what you need.

If you’ve ever had a conversation with ChatGPT or Claude, you already understand the core skill involved. You’re describing what you want, checking the result, and refining. The quality of your prompts shapes the quality of what you get back, just like any other AI interaction.

The tools people use for vibe coding include Replit, Cursor, Bolt, and Google’s AI Studio. Some run entirely in your browser. Others sit inside code editors. But they all work the same way: you type what you want in plain English, and the AI handles the technical bits.

What Vibe Coding Is Good For

Here’s where I’ll push back on the hype slightly. Vibe coding is genuinely useful, but not for everything.

It’s brilliant for personal projects. The kind of small, specific tools that only you will ever use. A tracker for your running habit. A simple dashboard for your side business. A quiz app for your kids. Things that would take a developer a few hours to build but would never be worth hiring someone for.

It’s also excellent for learning. When the AI generates code, you can ask it to explain what each part does. You start to recognise patterns. You pick up concepts without sitting through a course. It’s like learning a language by having conversations instead of studying grammar textbooks.

And it’s fast for prototyping. If you have a business idea and want to test whether it works before investing real money in development, vibe coding can get you a working prototype in hours rather than weeks.

Where Vibe Coding Falls Apart

Here’s the part that most breathless articles skip.

The code AI produces during vibe coding often works, but it’s not always good code. A Stack Overflow experiment with vibe coding found that the output was messy, poorly organised, and difficult for experienced developers to even review. The code ran, but nobody could understand why or how.

For a personal project that only you use, this doesn’t matter much. For anything with real users, real data, or real money involved, it matters enormously.

Security is the biggest concern. If you don’t understand the code, you can’t spot the vulnerabilities. People have built apps with vibe coding only to discover their API keys were exposed, their user data was accessible to anyone, or their payment integration had gaping holes. You can’t fix what you can’t see.

Maintenance is the other problem. Software needs updating. Bugs appear. Features need changing. If the original code is a tangled mess that nobody (including you) understands, every small change becomes a battle. The AI that wrote it might not even produce consistent results the second time around.

This is where understanding context windows becomes practical. The AI can only work with the information in its current conversation. As your project grows, it loses track of earlier decisions. Things start breaking in unexpected ways.

The Honest Take for Beginners

Vibe coding is worth trying. It’s a genuinely accessible way to build things with AI, and the feeling of describing an idea and watching it come to life is remarkable.

But treat it as what Karpathy originally described: a tool for quick experiments and personal projects. Not a replacement for understanding what you’re building.

The skill that makes vibe coding work isn’t technical knowledge. It’s the same skill that makes every AI interaction work: being clear about what you want, giving enough context, and knowing when the result isn’t good enough. In other words, prompting well.

If you can describe a problem clearly to a chatbot today, you can vibe code tomorrow. Start small. Build something just for yourself. And pay attention to what the AI produces, not just whether it runs.

Stop treating vibe coding as a shortcut to becoming a developer. Start treating it as a new way to think about what you want to build. The results will be better for it.
