Vibe Coding Explained: What It Is and What It Is Not

Vibe Coding Has a Definition Problem

Andrej Karpathy coined the term in February 2025 and the internet immediately started using it to mean five different things. Some developers use it to describe any workflow involving an AI coding tool. Product managers use it to pitch no-code platforms. Founders use it to mean shipping fast without a technical co-founder. None of these are wrong exactly โ€” but none of them are precise.

The confusion matters because vibe coding, AI-assisted coding, no-code, and traditional development are four genuinely different approaches with different trade-off profiles. Conflating them leads to wrong tool choices, misaligned hiring decisions, and products built on foundations that cannot hold the weight put on them.

This post defines each approach precisely and explains where each one breaks down.


๐ŸŽฏ Quick Answer (30-Second Read)

  • Vibe coding: You describe intent in natural language, the model writes and runs the code, you do not read or understand what was generated
  • AI-assisted coding: A developer writes code with AI acceleration โ€” Copilot, Cursor, Claude โ€” but owns and understands every line
  • No-code: Visual builders replace code entirely โ€” Webflow, Bubble, Glide โ€” no model involved in generation
  • Traditional development: A developer writes every line manually with no AI in the loop
  • Key distinction: Vibe coding outsources understanding to the model; AI-assisted coding keeps understanding with the developer
  • Recommendation: Use vibe coding for throwaway prototypes; never for production systems you need to maintain or debug

The Four Approaches, Defined Precisely

Traditional Development

A developer writes every line of code. They understand the architecture, the logic, the failure modes. Debugging means reading the code. Extending means understanding the existing codebase before adding to it. The developer is the system's source of truth.

This is slow by modern standards but produces systems whose behaviour is fully understood by the people maintaining them.

AI-Assisted Coding

A developer uses AI tools โ€” Cursor, GitHub Copilot, Claude Code โ€” to accelerate their work. The AI suggests completions, generates boilerplate, explains unfamiliar APIs, and helps debug. The developer reviews, modifies, and approves every suggestion. They understand what the code does before it ships.

The mental model: the AI is a fast junior engineer. The developer is still the architect and the final reviewer. Productivity goes up; understanding stays with the human.

No-Code

Visual builders replace code entirely. Webflow, Bubble, Glide, and Airtable let non-developers build functional products through drag-and-drop interfaces and configured logic. There is no code generation โ€” the platform outputs code internally, but the user never sees it.

The ceiling is the platform's feature set. The floor is very low โ€” anyone can start building immediately.

Vibe Coding

Karpathy's original definition: you describe what you want in natural language, the model writes the code, you run it, you see if it works, you describe the next thing. You do not read the code carefully. You do not necessarily understand what was generated. You are steering by outcome, not by implementation.

The mental model is closer to a product manager directing a developer than a developer writing code. The difference from AI-assisted coding is the understanding layer. In vibe coding, the model holds the implementation details. In AI-assisted coding, the developer does.


Where Each Approach Breaks Down

Traditional development breaks down on speed. A solo founder building a product manually competes against teams using AI acceleration. The productivity gap is real and growing.

AI-assisted coding breaks down when developers over-trust suggestions without review. An accepted completion that introduces a security vulnerability or a subtle logic error is harder to catch because the developer did not write it from scratch. The review discipline has to be higher, not lower, than traditional development.

No-code breaks down at the platform ceiling. When your product needs logic the platform cannot express โ€” complex data models, custom integrations, performance requirements โ€” you hit a wall that cannot be climbed without leaving the platform. Migrating off is expensive.

Vibe coding breaks down the moment the product needs to be maintained, debugged, or extended by someone who did not generate it. A codebase nobody understands is a liability. When production breaks at 2am, "I described it to Claude and it worked" is not a debugging strategy. Vibe-coded systems accumulate technical debt invisibly because there is no human holding the model accountable for the quality of what was generated.


The Better Way vs The Wrong Way

The right approach is matching the method to the stakes and the lifespan of what you are building. Vibe coding is genuinely the right tool for a throwaway prototype, a one-time data migration script, or a personal tool you will use twice. The speed is real. The lack of understanding does not matter if the artefact is disposable.

AI-assisted coding is the right tool for production systems. You get the acceleration without surrendering the understanding. The review layer is non-negotiable.

The wrong approach is vibe coding your way to a product with paying customers and then trying to hire engineers to maintain what was generated. The codebase is often a tangle of AI-generated patterns with no consistent architecture, no test coverage, and logic the original builder cannot explain. Engineers quote six weeks to understand it before they can extend it safely. The speed gained during building is paid back with interest during maintenance.


My Take

The reason vibe coding became a cultural moment rather than just a technique is that it surfaced a question the industry had been avoiding: how much does developer understanding of their own codebase actually matter? For a long time the answer was obviously "completely" โ€” you cannot maintain what you do not understand. Vibe coding challenges that for a specific class of artefact: the throwaway prototype, the personal script, the quick validation tool. For those, the answer is genuinely "less than you think." The best outcome is a generation of founders who validate faster, waste less time building the wrong thing, and only invest in a real codebase once product-market fit is established. The worst outcome is production systems built by vibe coding that nobody can maintain, extending technical debt from months to years, with no engineer able to confidently say what the system will do under edge cases. Right now the industry is rationalising this in real time โ€” the teams using vibe coding for exploration and AI-assisted coding for production are shipping faster than both the purists and the ones vibe coding everything. Where this is heading: the distinction will matter less as AI agents improve at maintaining their own generated codebases โ€” but we are not there yet, and the teams treating generated code as if it comes with the same reliability guarantees as reviewed code are making a bet the tooling has not yet earned.

Real Developer Use Case

A solo founder used vibe coding to build a working MVP in four days โ€” a lead enrichment tool that scraped LinkedIn data, ran it through an LLM, and wrote results to a spreadsheet. The demo worked. Investors were impressed. They raised a small round and hired two engineers to productionise it.

The engineers spent three weeks reading the generated code before they could safely touch it. There were no tests, three different HTTP client libraries used inconsistently, and error handling that swallowed failures silently. The rewrite took six weeks. The founder's four-day sprint cost the company two months of engineering time.

The right call: vibe code the proof of concept, then build the production version with AI-assisted coding from a clean architecture. The prototype validated the idea. It should never have become the foundation.


Frequently Asked Questions

Is vibe coding just another name for AI-assisted coding?

No. AI-assisted coding keeps the developer in the understanding loop โ€” they review and own every line. Vibe coding explicitly outsources understanding to the model. The developer steers by outcome rather than implementation. Karpathy's original framing was deliberate: you are vibing with the output, not engineering it.

Can you use vibe coding for production apps?

For simple, low-stakes production tools with a narrow scope and an owner who can regenerate the whole thing if it breaks โ€” sometimes. For anything with user data, payment flows, complex state, or a team that needs to maintain it โ€” no. The lack of human understanding of the codebase creates risk that compounds over time.

What is the difference between vibe coding and no-code?

No-code uses visual builders โ€” no code is generated that you could read. Vibe coding generates actual code through natural language prompts. The output of vibe coding is a codebase. The output of no-code is a configured platform deployment. They have different ceilings, different failure modes, and different migration paths.

When should a developer use vibe coding?

For disposable artefacts: throwaway scripts, one-time data transforms, personal tools, quick demos, and proof-of-concept prototypes that exist to validate a question and be discarded. The moment the artefact needs to be maintained, extended by someone else, or trusted with user data โ€” move to AI-assisted coding with proper review.

Does vibe coding produce worse code than AI-assisted coding?

The code quality from the model is often similar. The difference is the review layer. AI-assisted coding has a developer reading and approving every significant piece. Vibe coding skips that layer. A senior developer using AI-assisted coding produces maintainable, reviewed code. Vibe coding produces whatever the model generated, unfiltered โ€” which may be excellent or may contain subtle problems nobody will catch until they matter.


Conclusion

Vibe coding, AI-assisted coding, no-code, and traditional development are four distinct approaches with different trade-offs. The label you use matters less than understanding which one you are actually doing and whether it matches what you are building.

Vibe code disposable things. Use AI-assisted coding for anything you need to maintain. Understand the difference before you are three months into a product and realise you have a codebase nobody can explain.
