So, what is vibe coding? It is building software by describing what you want in plain language and letting an AI write the code, while you judge the result by running it and not by reading it. You type a request, the app appears, you say what is wrong, and the loop repeats. The term is less than two years old and already in the dictionary. This post explains where it came from, how the loop works, where it breaks, and which tools fit which kind of person. If you want to feel it before reading on, describe an app to Lovable and watch it build.
Where the Term Came From
Andrej Karpathy, a co-founder of OpenAI and former head of AI at Tesla, coined it in a post on X on February 2, 2025. He described a new way of working in which you “fully give in to the vibes” and stop thinking about the code at all. He was talking about weekend projects, and he said so.
The phrase escaped anyway. Within months it was a job description, a startup category and a punchline. Collins Dictionary then named vibe coding its Word of the Year for 2025.
It also drifted. Karpathy meant not reading the code. Today many people use the phrase for any programming done with an AI assistant, which is a different thing, as the next sections show.
How Vibe Coding Works
The loop has five steps, and none of them requires knowing a programming language.
- Describe the result. For example: a booking page for a hair salon, with a calendar, three services and email confirmation.
- Let the AI build. The tool writes the files, sets up a database if needed, and shows a live preview.
- Try it like a user. Click everything. You are the tester, not the reviewer.
- Report what is wrong. Paste the error or say what you expected. The AI changes the code.
- Repeat, then publish. Most builders deploy to a public link with one button.
That is all. The skill moves from writing syntax to describing behavior clearly, and to noticing when something is off.
Vibe Coding vs AI-Assisted Coding
The two get mixed up constantly. Programmer Simon Willison drew the line most clearly: if you review, test and understand what the AI wrote, you are using an assistant, and that is not vibe coding.
| Vibe coding | AI-assisted coding | |
|---|---|---|
| Who reads the code | Nobody, or only when stuck | The developer, every change |
| Typical tool | An app builder in the browser | An editor or terminal agent |
| Good for | Prototypes, internal tools, personal apps | Products with users and data |
| Main risk | Hidden security and logic bugs | Slower, needs real skill |
| Who does it | Founders, designers, marketers | Working engineers |
Neither is better. They are different amounts of trust placed in the machine, and the right amount depends on what breaks if the app is wrong.
Which Tools Are Used for Vibe Coding?
They split into two families, and choosing the wrong one is the most common beginner mistake.
App builders run in the browser and hide the code. Lovable is the quickest route from prompt to prototype, as our Lovable review found. Base44 suits non-technical teams because database, login and hosting come built in. Replit sits in the middle, with a builder on top of a real coding environment.
Code editors and agents assume you can read what they produce. Cursor, Claude Code, GitHub Copilot and Windsurf belong here, and the Cursor AI review covers the best known of them.
We compare ten of them side by side in the best vibe coding tools roundup, and the best AI app builder list goes deeper on the no-code side.
Try Lovable FreeThe Risks Nobody Mentions in the Demo
A demo ends when the app appears. The problems start afterward.
- Security. Code you did not read can expose an API key, skip a permission check or leave a database open. It will still look finished.
- Maintenance. Six weeks later a change breaks something, and nobody knows why, because nobody ever understood how it worked.
- Cost. Builders charge in credits, and a stubborn bug can burn through a month of them in one evening.
- Skill. Leaning on the tool without learning anything leaves you stuck at the first hard problem, a point Zoho founder Sridhar Vembu made bluntly.
Therefore the sensible rule is about stakes. Vibe code freely when a failure costs you an afternoon. Bring in someone who reads code before the app touches payments, health data or other people’s passwords. The numbers on whether all this actually saves time are in our AI coding tools productivity report.
Frequently Asked Questions
What is vibe coding in simple terms?
Telling an AI what software you want in plain language and accepting the code it writes without reading it. You steer by trying the result and describing what to change.
Who coined the term vibe coding?
Andrej Karpathy, in a post on X on February 2, 2025. Collins Dictionary later named it Word of the Year for 2025.
Is vibe coding real programming?
It produces real software, but it skips the part programmers consider essential, which is understanding the code. Most professionals treat it as a prototyping method.
Can you vibe code without knowing how to code?
Yes. App builders such as Lovable and Base44 are designed for that. Knowing a little helps you describe problems and spot bad answers.
Is vibe coding safe for a real product?
Not without review. Unread code can hide security holes, so anything that handles payments or personal data needs someone who can check it.
What is the best tool to start vibe coding?
A browser app builder with a free tier. Lovable is the easiest first step, and our vibe coding tools roundup lists nine alternatives.
