What is vibe coding?

It's not about writing code faster. It's about people who couldn't write code before now shipping real products. That's the actual shift.

The Definition

Vibe coding is a development approach in which the human directs software creation through natural language prompts rather than writing code manually. The AI โ€” typically a large language model with code generation capabilities โ€” produces the implementation. The human's job is architectural clarity, iterative direction, and taste: knowing what to build, being able to evaluate whether what came back is right, and knowing what to change when it isn't.

01 โ€” The Real Shift

Who vibe coding is actually for

Most of the discourse around vibe coding is written by engineers. So most of it frames the practice as "engineers writing faster" or "engineers who can skip the boilerplate." That framing misses the more significant thing happening.

The people being most transformed by vibe coding aren't engineers โ€” they're strategists, designers, founders, and domain experts who had ideas that previously required a developer to realize. The gap between "I know what this should do" and "I can build this" has collapsed. That's a structural change in who gets to ship.

I've shipped over 20 web applications using AI-assisted development. I'm not a developer. I have a communication degree. The work I've done would have required either hiring an engineer or abandoning the idea. Now it requires a clear prompt, patience with iteration, and enough taste to know when the output is wrong.

The taste problem

The bottleneck in vibe coding isn't the AI's ability to write code. It's the human's ability to evaluate what they got. Taste โ€” knowing whether the thing that came back is right โ€” is the skill that can't be automated. It's what separates people who ship from people who get stuck in prompt loops.

02 โ€” In Practice

What vibe coding actually looks like

The typical description of vibe coding โ€” "just describe what you want and the AI builds it" โ€” is technically accurate and practically incomplete. Here's what the actual loop looks like when you're doing it from a non-developer starting point:

1

Define the thing clearly before you prompt

AI tools are good at building what you describe, not what you mean. The work before the first prompt โ€” getting specific about what the tool does, what the inputs and outputs are, what the edge cases are โ€” is the highest-leverage work in the entire process.

2

Start with structure, not features

Build the skeleton first. Get one thing working end-to-end before adding complexity. The temptation to spec out every feature upfront leads to 400-line prompts that produce tangled code no subsequent prompt can cleanly modify.

3

Evaluate outputs against intent, not against code quality

You can't read the code. What you can do is run the thing and assess whether it behaves correctly. Test every output against the use case it was built for. Describe what's wrong specifically โ€” "the submit button doesn't fire" is a better prompt than "this is broken."

4

Iterate toward quality, not toward done

Vibe coding produces working code faster than traditional development. It doesn't produce perfect code. The polish phase โ€” cleaning up edge cases, adding error handling, improving UX details โ€” often takes as long as the build phase. Ship when it's right, not when it runs.

03 โ€” The Ceiling

What vibe coding can and can't do

Vibe coding has a real ceiling, and being honest about it is more useful than pretending it doesn't exist. The ceiling is higher than most skeptics assume and lower than most evangelists claim.

Can do
Full-stack web applications

React, Next.js, Node, APIs, databases โ€” production-grade web apps with clean architecture are well within the capability envelope.

Can do
Rapid prototyping

Getting something real in front of users in hours instead of weeks. The speed advantage in validation cycles is significant and underestimated.

Hard
Complex system architecture

Multi-service systems, complex state management at scale, performance-critical infrastructure โ€” these require engineering judgment that AI-assisted tools currently struggle to maintain across a large codebase.

Hard
Debugging deep problems

When something breaks in a non-obvious way, the AI's suggestions can create circular loops. Understanding what's actually happening โ€” even at a conceptual level โ€” becomes necessary.

The consistent pattern: vibe coding excels when the problem domain is clear and the scope is bounded. It struggles when ambiguity compounds across many components simultaneously.

04 โ€” The Skill

What gets better with practice

The skill that compounds in vibe coding isn't syntax. It's prompt precision โ€” the ability to describe a technical requirement in language clear enough that the AI produces the right implementation with minimal correction.

Early vibe coders describe what they want. Experienced vibe coders describe what they want, why they want it, what the edge cases are, what the data shape looks like, and what success looks like. That additional context collapses the iteration cycle significantly.

The second skill that compounds is pattern recognition. After building enough things, you start to recognize when an output looks structurally wrong before you even run it. You develop intuitions about what kinds of prompts produce what kinds of problems. This is functional technical literacy without formal training.

The compounding effect

Every application you ship teaches you something about what works. The value isn't just the product โ€” it's the accumulated prompt craft and technical intuition that makes the next one faster. The first app takes weeks. The fifth app takes days. The twentieth app takes hours.

Where This Gets Complicated

What's still unresolved

Does vibe coding produce maintainable code? Most practitioners report that vibe-coded codebases are harder to maintain than engineer-written ones โ€” more redundancy, less consistent patterns, weaker abstractions. As projects age and require changes, the technical debt question becomes real. Whether this is a tooling problem or a fundamental constraint is still being worked out.

What's the professional framing? "AI-assisted development" is the enterprise-safe term. "Vibe coding" is the honest term. How this practice gets named and positioned in professional contexts matters for how it's valued. Right now both framings coexist โ€” and the one you use signals something about your audience.

Does this change what non-technical roles are worth? Strategy, product sense, and domain expertise have always been undervalued because they were disconnected from the ability to build. If vibe coding closes that gap, the value of those skills may be about to be repriced. I think it does. I'm not certain the market agrees yet.

Where does the ceiling move next? Twelve months ago, the things I build now weren't achievable through vibe coding at any level of skill. The ceiling moves consistently upward as models improve. The question isn't whether vibe coding is capable enough today โ€” it's where capable enough lands in 18 months.
