What Is Vibe Coding? A Beginner's Guide

If you’ve been anywhere near tech posts on X in the last year, you’ve probably seen the term “vibe coding.” It sounds like something a Silicon Valley parody would invent, but it’s real — and it’s changing who gets to build software.

Here’s the plain-English version.

What Is Vibe Coding?

Vibe coding is building software by describing what you want in natural language — plain English — instead of writing code yourself. You tell an AI tool what you want, and it writes the code for you.

The term was coined by Andrej Karpathy, a well-known AI researcher, in a February 2025 tweet that went viral. His point was simple: you don’t need to understand the code. You just need to describe the “vibe” of what you want, and the AI figures out the rest.

For example, instead of writing code yourself to create a button that saves data, you’d say:

“Add a save button that stores the form data and shows a success message.”

The AI writes the code, you test it, and if something’s off, you describe what needs to change. That’s it.

Why Does It Matter?

Before vibe coding, building software required years of learning programming languages and tools. The barrier to entry was enormous.

Now, anyone with a clear idea of what they want to build can actually build it. You don’t need a computer science degree. You don’t need to know any programming language. You need to be able to describe what you want clearly.

That’s a massive shift.

How Does It Work in Practice?

Here’s what a typical vibe coding session looks like:

You describe what you want. “I need a website that shows blog posts, has a dark theme, and lets people search by tags.”
The AI generates the code. It creates files, writes the logic, and sets up the structure.
You test it. Open the site, click around, see if it works.
You refine. “The search isn’t working right — it should filter as I type, not after I press enter.”
The AI fixes it. It reads your feedback, updates the code.

You repeat steps 3-5 until you’re happy. The whole process feels more like directing than coding.

What Tools Can You Use?

There are two main types of vibe coding tools:

Browser-Based Platforms (easiest to start)

These run entirely in your web browser — you describe your app, they build and host it for you. No setup required.

Replit — browser-based, can deploy (make your project live on the internet) with one click
Lovable.dev — turns descriptions into working apps fast
Bolt.new — builds complete apps from descriptions

I haven’t used these personally, so I can’t give a firsthand review. But they’re popular starting points if you want zero setup.

AI Coding Assistants (more control)

These run on your computer and give you more flexibility, but take a few minutes to set up.

Claude Code — runs in your terminal (the text-based app where you type commands) and understands your entire project. It can make changes across multiple files at once. This is what I use to build everything.
Cursor — a code editor with AI built in, good if you prefer a visual interface
GitHub Copilot — suggests code as you type, better for people with some coding knowledge

What Can You Actually Build?

More than you’d think:

Websites and blogs
Web apps and dashboards
Browser extensions
Services that connect different apps together
Scripts that automate repetitive tasks on your computer
Mobile app prototypes (early working versions)

I built a full AI-powered blog engine — with daily automated posts, a Telegram bot, quality review, and automated deployment (it publishes itself without me doing anything) — using vibe coding. I put it up for sale on Gumroad. And I’d never built a real product before I started.

What Are the Limits?

Let’s be real about what vibe coding can’t do well (yet):

Complex behind-the-scenes logic — things like payment processing or real-time multiplayer games still need expertise to get right
Speed and efficiency — the AI writes code that works, but it might not be the fastest possible version
Security — keeping your app safe from attackers is important. The good news is you can ask your AI tool to review your project for security issues — I do this with every project I build. You don’t need to be a security expert, but you should make it a habit to ask.
Tricky bugs — sometimes things break in ways that are hard to describe to the AI

These aren’t dealbreakers. They’re just things to be aware of as you build.

How to Get Started

Pick a tool. If you want zero setup, try a browser-based platform like Replit or Lovable. If you’re willing to spend 20 minutes setting things up, go straight to Claude Code — it’s the most capable. Here’s our step-by-step Mac setup guide.
Start small. Build a personal website or a simple tool. Don’t try to build the next Uber on day one.
Learn to describe what you want. The better your descriptions, the better the output. Be specific about what you want and what’s not working.
Don’t be afraid to break things. You can always tell the AI to undo what it just did.

The Bottom Line

Vibe coding is real, it works, and it’s only getting better. If you have ideas but thought you needed to learn to code first — you don’t. Not anymore.

Start building. You’ll be surprised at what comes out.
