What Is Vibe Coding? The New Way Entrepreneurs Build
In early 2025, Andrej Karpathy — former director of AI at Tesla and one of the most respected AI researchers in the world — posted a short description of how he'd been building software lately. He called it "vibe coding." The term stuck.
Karpathy described a mode of programming where he mostly gave up trying to understand every line of code. Instead, he'd tell an AI what he wanted, the AI would write it, he'd run it, see what happened, tell the AI what needed fixing, and repeat. He was riding the "vibes" of what the AI produced rather than carefully engineering each piece.
The tech world latched onto the term because it described something real: a genuinely new relationship between humans and code. Whether that's exciting or alarming depends on what you're trying to build.
The Origin of the Term
Karpathy's tweet in February 2025 was characteristically understated for something that sparked this much discussion. His point wasn't that vibe coding is better than traditional programming, or that it replaces expertise. He was describing an observation: for certain kinds of small projects, personal tools, and experimental work, you can get surprisingly far by just... talking to the AI and accepting what it gives you.
The viral moment happened because it resonated with a lot of people who had quietly been doing the same thing. Startup founders building quick prototypes. Product managers hacking together internal tools. Designers building out landing pages without a developer. All of them had discovered that modern AI coding tools — Claude Code, Cursor, Replit AI, v0.dev — could handle far more than anyone expected if you just described what you wanted clearly.
Karpathy's framing also carried implicit permission: you don't have to understand everything the AI writes. That was a radical departure from how coding had always been taught and practiced.
How Vibe Coding Actually Works
The process is more structured than the name implies. Here's what vibe coding actually looks like in practice:
You start with a clear description of intent. Not "make me an app," but "I want a web page where people can enter their email address to join a waitlist, and when they submit, their email gets saved and they see a thank-you message." The more specific you are, the better the result.
The AI generates code. Depending on the tool, this might be an entire project scaffold, a single component, or a series of files. Tools like v0.dev are particularly good at generating UI components. Claude Code and Cursor work better for full project implementation.
You run it and see what happens. Sometimes it works perfectly. Often there are issues — a button doesn't do what you expected, a form doesn't submit correctly, the styling is off. You describe the problem to the AI and it revises.
You iterate. The loop of describe → generate → test → describe again is the core of vibe coding. You're acting as a product manager giving feedback to a developer, not as the developer yourself.
You ship. When it works well enough, you deploy. For a landing page or a simple tool, "well enough" can mean "works on the first try." For anything more complex, it takes more iterations.
The key distinction from traditional development is that you're steering the process through natural language rather than writing the code yourself. You're the one who knows what you want. The AI is the one who knows how to build it technically. The question is how clearly you can communicate the former to enable the latter.
Tools That Enable Vibe Coding
The tools have evolved rapidly. As of 2026, the ones worth knowing about:
Claude Code is Anthropic's agentic coding tool — runs in the terminal, can work autonomously across a whole codebase. Best for developers or technical entrepreneurs who want to accelerate real software projects. Less suited for complete beginners because it requires you to understand what it's doing.
Cursor is a code editor built around AI, using Claude or GPT-4 as the underlying model. It has a "Composer" feature that can make multi-file edits based on natural language. Good middle ground — powerful but more approachable than pure command-line tools.
Replit is a browser-based development environment with built-in AI. You can build, run, and deploy without installing anything locally. The easiest entry point for true beginners who want to try vibe coding with minimal setup.
v0.dev (by Vercel) specializes in generating React UI components from text descriptions or sketches. You describe or sketch what you want, and it generates copy-paste-ready React code. Exceptional for front-end UI work.
Bolt.new is similar to Replit in concept — browser-based full-stack development with AI. Strong for building small web apps quickly.
None of these tools require you to write code to get started. But they reward you more generously as your technical understanding deepens.
What You Can Realistically Build With Vibe Coding
Being honest about this matters, because the hype tends toward either excessive optimism or dismissive skepticism.
What works well:
Landing pages and marketing sites. This is the sweet spot. Describe the sections you want, the colors and fonts you like, the copy you've written — and a tool like v0.dev or a Claude Code session can produce a polished landing page in an afternoon. Quality may vary, and you'll likely need to iterate on details, but the starting point is far better than a blank page.
Internal tools. Spreadsheet replacements, simple dashboards, data entry forms, basic CRMs for small teams. If the data is not complex and the user base is small and forgiving, vibe coding can build tools that save hours per week for relatively small projects.
MVPs and prototypes. The best use case for startup founders: build a working demonstration of your idea quickly to test the concept before investing in proper engineering. The code quality may not be production-ready, but the functionality can be real enough to show investors or gather user feedback.
Personal and side projects. Things for yourself, your team, or a small community — where imperfection is tolerable and shipping speed matters more than robustness.
What doesn't work well:
Complex enterprise systems. Applications that handle sensitive financial or health data. Anything that requires deep integration with legacy systems. Applications where performance matters at scale. Products that will be maintained by a large engineering team for years. In all of these cases, the shortcuts vibe coding enables in the short term create significant problems later.
The Real Limitations
The name "vibe coding" is a bit misleading because it implies the process is effortless. It isn't. Here's what actually makes it hard:
You're the product manager. Every decision about what the software should do, how it should behave at the edges, what error states look like, how it handles unexpected input — those are your decisions. The AI executes on whatever direction you provide. If your direction is incomplete or inconsistent, the result will reflect that.
The AI makes mistakes. Modern AI coding tools are remarkably capable, but they're not infallible. They can generate code that looks correct but has subtle bugs. They can misunderstand an ambiguous description and build something different from what you imagined. They can write code that works in testing but fails under real-world conditions.
Debugging requires some technical literacy. When something breaks — and things break — you need to be able to describe the problem clearly enough for the AI to fix it. "It doesn't work" is not enough information. "When I click the submit button, nothing happens, and the browser console shows an error that says 'TypeError: Cannot read property of undefined'" gives the AI something to work with. Getting to that second description requires knowing how to open a browser console and read an error message, at minimum.
Context limits create drift. In long sessions, AI tools can lose track of earlier decisions or accumulate inconsistencies across the codebase. Experienced vibe coders learn to work in focused sessions, commit progress regularly, and give the AI clear context about what already exists when starting a new session.
Is Vibe Coding Right for You?
A few questions to help you decide:
Do you have a specific, limited thing to build? Vibe coding is well-suited to well-defined problems. "I need a landing page with an email capture form" is a great vibe coding project. "I need to build a social network" is not.
How much technical tolerance do you have? If the idea of reading an error message and figuring out what it means feels completely overwhelming, vibe coding will be frustrating. If you're comfortable with a bit of ambiguity and willing to learn a little, it's accessible.
What happens if it breaks? A personal project or an internal tool that a few people use has different risk tolerance than a customer-facing product or anything that handles real financial transactions. Match your approach to your risk tolerance.
Do you have a timeline? Vibe coding for a demo or prototype is faster than traditional development. Vibe coding for a production product often takes longer than you expect, because the iteration cycles for getting things right can accumulate.
When You Still Need a Developer
Vibe coding is a genuine capability shift, but it hasn't eliminated the need for professional developers. It has changed what you bring to those developers.
If you need a secure, scalable, maintainable application — if you're building something that will handle customer data, process payments, integrate with complex systems, or be maintained and extended over years — you need engineers who understand architecture, security, performance, and long-term maintainability. Vibe coding doesn't replace that judgment.
What it can do: help you validate your idea before you invest in proper engineering. Help your team knock out internal tools without developer time. Help you communicate more clearly with developers about what you want, because you've spent time interacting with an implementation already.
