As you’ve followed the Twitterverse, you may have encountered the phrase, “What is vibe coding?” Perhaps a developer pal said something interesting. Perhaps you’ve noticed it posted on #X, or perhaps you’re just fed up with this new word you’re racking your brain over, and want clarification.
Now, vibe coding is a thing in which software is designed by entertaining an AI to develop it, wanted in regular discourse, instead of writing it out and operating it manually.
No syntax. No semicolons. No experience from computer courses. Write the outcome of your wish. The AI writes it. You examine the outcome, request the alterations, and try again till it satisfies.
Really, it’s quite seamless, isn’t it? But it has altered our perception of creation for millions, and, quite truthfully, after studying this issue, I believe most online explanations confuse the issue.
Where the Term Actually Came From
It’s not a nebulous techno-jargon piece; it’s morphed over a long period. Has an exact birthday.
The poster you may have complicated connections to, Andrej Karpathy, who also served as head of AI at Tesla and was a co-founder of OpenAI, stopped many people halfway into their latest scroll last Feb. 2 on X. He says that there’s a new way to code: “The vibes should take over, exponentials should be embraced, and the code itself is forgotten.
It was a post that received 4.5M views. In just a matter of weeks, The Guardian, Ars Technica, and The New York Times all had contributions about it. Thus, Collins Dictionary announced ‘what is vibe coding’ as its Word of the Year at the end of 2025. Karpathy was actually talking about a very specific feature: giving an AI coding agent a specific task and inputting all the output, only to get back a problem when it produces something broken instead. You’ve got faith in the process, and you stay the course.
How it Actually Works, Step by Step
I’ll explain a bit about how this works in practice because conceptually it sounds a lot better once you see the real implementation of how it works.
Step 1: You start a tool, such as Cursor, Replit, or Claude Code, and write down a line of code corresponding to a service description, for instance, “build me a website where people can sign up for a newsletter and see a list of past issues.
Step 2: AI spits out the real code — all the designs for users, database schema, sign-up process, you name it — in seconds to minutes.
Step 3: You are seeing what comes out. The working program, not the code! Do the signs work? Does it seem nicely done?
Step 4: Have you got a problem? Do not fix the code. It’s as simple as saying, “the button is the wrong color” or “it’s not saving emails properly,” and the AI takes care of the rest.
Repeat Step 5 until it is done as desired.
That’s it. That’s all the workflow. No need for a computer science degree!
Why This Matters for Regular People, Not Just Developers
The part that I think really is the most important is what vibe coding is, more than a developer productivity hack. It has made software technologies accessible to people who had no ability to create anything in the past.
Even if your small business is without any coding skills now, you can construct a custom booking system for your shop. A teacher can create a Quiz App within 4 hours for a classroom. A person with a great idea for a simple tool doesn’t require being able to write some Python code first; they can just be a description of what they want.
Today, approximately 92% of desktop developers say they have some experience with AI coding, and the number of “absolute beginners” programming actual software has increased manifold. The Space between having an idea and having an actual product has shrunk dramatically.
The Honest Downsides Nobody Tells You About
I’m going to be honest, and this is what I want most of the articles to say so far are doing half the job, they mostly talk about the cool half of the story.
The result of what is vibe coding is hard to understand code that no one knows, even the one ‘written’ by it. And that presents actual issues if you attempt to expand past a simple pastime.
According to research in 2026, 40%-62% of AI-generated code has security vulnerabilities. According to one, AI-generated code is only successful in protecting against cross-site scripting attacks 86% of the time. A total of 35 new security vulnerabilities linked to AI-generated code were traced to the code itself in March 2026 (compared with 6 in January of the same year).
The speed is real. The threat is not just a theoretical one. In case you intend to produce a quick personal project or prototype, or something for fun, none of these is a significant worry. However, when you’re working on something involving actual user information, bills, or any sort of sensitive data, “I don’t really know how this code works” becomes a major issue.
Vibe Coding vs “Agentic Engineering” – The New Twist
This, which most articles on vibe coding fail to bring up altogether, they’re pretty new.
In February 2026, one year after his first post, Karpathy returned with an insightful comment: “Vibe coding, as I first thought of it, is already starting to feel like an antiquated form of programming.” Not because it didn’t work well, but because the tools became much better, so something else took its place that was more structured.
Now, he says agentic engineering is taking center stage. It’s a fine but significant nuance. Vibe coding is where you believe all of the AI has to say without question and simply follow along. Agentic engineering involves actually running multiple “AI agents,” critically evaluating their output, and taking the process seriously like real engineering, but at a faster pace.
You don’t write the code like you normally do 99% of the time anymore, but you are still responsible for its quality when you ship it. Think less ‘forget the code exists,’ and more ‘orchestrate the agents and be accountable.
This is important because if you’re learning vibe coding this year (2026), you’re learning something that the vibe coding community is moving into its next iteration.
Should You Try Vibe Coding?
Anyone who ever wanted an idea for an app, a tool, or a website but thought they would have to learn how to code first should rethink that notion.
Start small. Do something simple: Your personal tracker, a basic website, a small tool to address 1 nuisance in your life. Head through a tool such as Replit Agent or Cursor, stating in common terms what you wish.
You will be amazed at what you can accomplish in one afternoon! However, do not construct this type of payment system for your bank – at least not yet.
Quick Recap
| Question | Answer |
| Who coined the term? | Andrej Karpathy, February 2025 |
| What does it mean? | Building software by describing it in plain language to AI |
| Do you need coding experience? | No, that’s the whole point |
| Is it risky for a production app? | Yes, security flaws are common |
| What’s replacing it? | “Agentic Engineering,” a more structured version |
Vibe coding made developers faster and, more than that. It made no grand announcement that it was breaking down the barriers between “software builders” and “non-software builders.” It’s likely to be either exciting or concerning, as it depends on what you are attempting to construct, but it’s not the result.
