What is Vibe Coding?
The AI revolution that lets anyone build software just by describing what they want — in plain English.
Vibe coding means telling an AI AI (Artificial Intelligence) — A computer system that can understand human language and generate responses, code, images, and more on its own. what software you want to build — in plain language, like chatting — and the AI writes all the code for you. You don’t need to know programming. You just describe the vibe of what you want, and the AI builds it.
Imagine you want to build a to-do list app. Instead of spending weeks learning to code, you just type: “Build me a to-do list app where I can add tasks, mark them done, and delete them.” The AI builds it instantly.
The term was coined Coined — When someone creates a brand new word or phrase that didn’t exist before. by computer scientist and OpenAI co-founder Andrej Karpathy. It became so popular that Collins Dictionary named it the Word of the Year 2025.
The story of vibe coding is surprisingly recent. Here’s how it went from a tweet to the tech world’s biggest trend:
GitHub Copilot Launches
AI code-suggestion tools emerge. At first, they just autocomplete a line or two — helpful, but not revolutionary.
LLMs Get Dramatically Better
LLMs LLM (Large Language Model) — A type of AI trained on huge amounts of text that can understand and generate human-like language. Examples: ChatGPT, Claude, Gemini. like Claude, GPT-4 and Gemini become powerful enough to write entire programs from a simple description.
Karpathy Coins “Vibe Coding”
Andrej Karpathy posts on X (formerly Twitter), describing a new style of programming where you “forget the code even exists.” The post goes viral overnight.
25% of Y Combinator Winter 2025 Cohort: 95% AI-Generated Code
TechCrunch reported this figure in March 2025 — a stunning sign that the trend is mainstream in the startup world.
Collins Word of the Year
Vibe coding officially enters the dictionary. It’s no longer just a trend — it’s part of our language.
A $4.7 Billion Market
The vibe coding market is valued at approximately $5.5–7.4 billion in 2025, depending on scope definition, with forecasts ranging from $12 billion to $48 billion by 2032–2035.
The process is surprisingly simple. You don’t write a single line of code yourself — you just have a conversation with AI.
Describe What You Want
Type what you want in plain English. “Build a recipe app where I can save, search and rate my recipes.”
AI Writes the Code
The AI model AI Model — The “brain” behind AI tools. It has been trained on billions of lines of code and can generate new code based on your instructions. generates all the source code Source code — The actual text instructions written in a programming language (like Python or JavaScript) that a computer understands and runs. instantly.
Review and Test
You run the app and see if it works. If something’s off, you tell the AI in plain language what to fix.
Iterate & Refine
Keep chatting with the AI to add features, change designs, or fix bugs — no coding knowledge required.
Deploy
Many vibe coding tools automatically deploy Deploy — Publishing your app online so other people can access it on the internet. your app to the internet with one click.
For the right use cases, vibe coding is genuinely transformative. Here’s what it does well:
🚀 Advantages
- Anyone can build software. No years of study required. A teacher, designer, or entrepreneur can now create apps, websites, and tools.
- 10× faster development. What used to take weeks of coding can be done in hours. Teams prototype ideas the same day they have them.
- Lower cost for startups. Instead of hiring a large dev team, small startups can build MVPs MVP (Minimum Viable Product) — The simplest version of a product that still works and can be tested with real users. fast and lean.
- Removes repetitive work. AI handles boring, repetitive coding tasks — developers can focus on creative problem-solving.
- Great for learning. Beginners can see working code instantly and learn from it.
- Democratises technology. People in regions without access to expensive CS education can now build tech products.
- Rapid prototyping. Ideas go from napkin sketch to working app in hours, enabling faster feedback cycles.
- No language barrier. You can prompt in your own language and build software without knowing English programming syntax.
Vibe coding is powerful — but experts have raised serious concerns. Here’s what you need to know:
Security Vulnerabilities
AI-generated code has 2.74× higher security vulnerability rates than human-written code. In May 2025, 170 out of 1,645 apps built with the tool “Lovable” had a critical flaw exposing users’ personal data.
Hidden Bugs
If you don’t understand the code the AI wrote, you may not even know there are bugs until something breaks badly — possibly in front of real users.
Hard to Scale
AI-generated code often works fine for small projects but falls apart when you try to grow. Code duplication Code duplication — When the same or very similar code appears in multiple places. This makes maintenance harder and increases the chance of bugs. increased 4× and code refactoring dropped from 25% to under 10% by 2024.
Hard to Maintain
Senior engineers in 2025 reported “development hell” working with AI-generated codebases — it’s often messy, poorly structured, and painful to update.
Junior Developers Struggle More
Experienced developers use AI to go faster. But junior developers often lack the skills to spot AI mistakes — meaning they sometimes ship broken or insecure code confidently.
Legal & Copyright Risks
AI models are trained on code from the internet. Sometimes the code they generate is too similar to copyrighted open-source code, which can create legal liability Legal liability — Being legally responsible for harm or violation of rules. If your product uses copyrighted code you didn’t write, you could face lawsuits. .
Industry analysts warn that businesses adopting vibe coding without proper governance risk accumulating “technical debt” — messy, unmaintainable code that becomes costly to fix later. A 2025 Veracode report found that 45% of AI-generated code fails OWASP Top 10 security tests.
