Vibe coding — the term coined by AI researcher Andrej Karpathy — refers to the practice of building software through natural language prompts to AI coding tools, without writing code directly. You describe what you want. The AI produces code. You describe what's wrong. The AI adjusts it. Repeat until the thing works.

It's fast. For building prototypes, testing ideas, and getting something in front of users quickly, it is genuinely transformative compared to what was possible three years ago. Non-technical founders are launching products. Entrepreneurs are automating workflows. Researchers are building tools for their own use that would have required a developer before.

What it isn't is a complete substitute for understanding software. The AI doesn't know your business. It doesn't know your users. It doesn't know what your system needs to be able to do in six months or what the security implications of a particular implementation are. It knows how to produce code that satisfies the prompt you gave it. The quality, coherence, and safety of what gets built depends on the quality of the thinking that goes into those prompts — and that thinking benefits enormously from understanding what the code actually does.

Vibe coding, in other words, is a capability multiplier. What it multiplies depends on what you bring to it.

"Learn to code" is advice that means different things depending on who's saying it and what level they have in mind.

At one end: deep computer science education. Algorithms, data structures, compilers, operating systems, distributed systems. Years of study. Genuinely powerful. Not what most people asking this question need.

At the other end: basic programming literacy. Understanding variables, functions, control flow, data types, APIs, and how the web works. How a database relates to the application layer. What happens when code runs. What an error message is actually telling you. Enough to read code and understand it, even if you can't produce it fluently.

The second version is more accessible than it sounds, more useful than it's often credited for, and — critically — it's what makes vibe coding actually work well rather than just sort of working.

A non-technical founder who has spent two months learning the fundamentals builds better prompts, catches more AI errors, asks better questions of developers, makes better product decisions, and — when the vibe-coded codebase needs professional attention — understands the audit report well enough to act on it intelligently.

That's not the same as being a developer. It's something different and something useful.

If you have an idea and you want to find out if it works — vibe code it.

The purpose of an early-stage prototype is to answer a question: does this solve a problem that people will pay to have solved? That question doesn't require production-grade code, a scalable architecture, or robust test coverage. It requires something that works well enough to show to real users and generate real feedback.

Vibe coding gets you to that stage faster and cheaper than any alternative. A no-code prototype that might take a weekend to build could take weeks with traditional development. A properly built custom MVP could cost £20,000–£60,000. Vibe coding lets you test the hypothesis before making either investment.

The discipline required to make this work: be honest with yourself about what a vibe-coded prototype is. It's a test instrument. It's not your product. It's the thing that tells you whether your product is worth building properly. Treating it as the product — launching it, scaling it, building on it indefinitely — is where the problems begin.

When the hypothesis is validated and you know you're building something real, that's when the question of how to build it properly becomes genuinely important.

If you're planning to build a technology business — not just test an idea, but actually build a product you intend to scale, raise investment on, and operate for years — some coding literacy is worth the investment. Not because you'll write all the code yourself, but because you'll make better decisions about everything technical if you understand the basics of what's happening.

You'll write better prompts for AI tools. You'll catch more of the problems AI tools introduce. You'll have more productive conversations with developers. You'll read a technical audit report and understand what it's saying. You'll evaluate development proposals without being entirely dependent on trusting whoever's proposing them.

More practically: learning enough to understand what code does — not necessarily to write it fluently — takes months, not years. Python specifically is the language most commonly recommended for this because it reads closely to English, is used across web development, data, automation, and AI, and has the most accessible learning resources of any language currently available. Two to three months of consistent effort produces meaningful literacy.

That literacy changes your relationship with the technical aspects of your business in ways that compound over time. Not because it makes you a developer. Because it makes you a more capable technical thinker — which is what you actually need.

‍

Vibe coding alone, without any technical foundation:

Fast to start. Increasingly limited over time. The codebase accumulates problems you can't diagnose. Developers you hire have to work around decisions the AI made that nobody understood. Security issues appear that nobody anticipated. At some point — usually when the product starts getting serious traction — the technical debt becomes a ceiling. You're building on sand, and you know it.

‍

Learning to code deeply, without building anything:

Genuinely useful knowledge that takes a long time to acquire and doesn't produce market validation or a product. Learning to code in isolation, without a real project to apply it to, is slow and often abandoned before it becomes useful. The motivation problem is real — programming concepts in the abstract are significantly harder to retain than programming concepts in the service of something you're actually trying to build.

‍

Vibe coding with basic technical literacy:

This is the combination that works. Fast prototyping. Better prompts. Recognising when the AI has produced something wrong. Understanding enough of the output to catch obvious problems. Building quickly with the judgment to know when "build it properly" has become the right next step.

‍

Learning to code while vibe coding:

The most effective learning path available right now, and one that most traditional programming education hasn't fully integrated. Use AI tools to build real things. Understand what the AI is producing — don't just accept it. When something doesn't work, understand why rather than just prompting your way around the error. This is how technical literacy develops fastest in practice.

There is a specific and legitimate use case for vibe coding without significant technical investment, and pretending otherwise would be dishonest.

If you're a non-technical founder building a prototype to test a specific business hypothesis — and you're genuinely committed to bringing in proper technical capability before scaling what you build — then vibe coding is the right tool for the job right now.

You're not building a product. You're building a test. The code doesn't need to be maintainable; it needs to be adequate. The architecture doesn't need to be scalable; it needs to be functional enough to get in front of users. The security doesn't need to be enterprise-grade; it needs to be adequate for the nature and sensitivity of the data you're handling.

The discipline is in the commitment to the next step — to either bring in professional development once the hypothesis is validated, or to invest in building the technical literacy that allows you to make better decisions as you grow. Using vibe coding as a permanent strategy for a serious product is a different choice, and an increasingly risky one.

If you're building a technology company — not a business that uses technology, but a business where the technology itself is the product — some genuine technical depth is worth the investment. Not necessarily developer-level depth. But enough that you can participate meaningfully in technical decisions, evaluate the quality of technical work being done, and identify when something is going wrong before it becomes expensive.

This particularly applies to: solo technical founders who are using AI tools to augment their capability (learning and vibe coding are entirely complementary); non-technical founders who want a genuine long-term understanding of what they're building; and anyone who expects to manage a technical team and wants to do so from a position of informed oversight rather than complete dependence.

It also applies, frankly, to developers who haven't engaged seriously with AI tools yet. The argument isn't "learn to code OR vibe code." It's "understand both, because both are now part of what professional software development looks like." A developer who can write excellent code and leverage AI effectively is a more capable developer than one who can only do the former. The reverse — someone who can use AI tools effectively but has no underlying technical understanding — has a shorter runway before the limitations become significant.

Since the most common path for people asking this question is "I'm going to vibe code for now, what do I need to know?" — here's the honest answer.

‍

Understanding what an error message is telling you

‍The single most useful skill for a vibe coder is being able to read an error message and understand, at least broadly, what category of problem it describes. This isn't about knowing how to fix every error — it's about knowing what kind of thing has gone wrong so you can describe it accurately to the AI or to a developer.

‍

Knowing the difference between frontend and backend

‍Not at a deep level — just enough to understand that "the page doesn't look right" is a different kind of problem from "the data isn't saving correctly," and that these problems live in different parts of the codebase.

‍

Understanding what an API is

‍Modern software is built from components that communicate via APIs. Knowing what this means — what an API call is, what a response looks like, what authentication means in this context — makes your prompts significantly more useful and your product decisions significantly better informed.

‍

Basic data structure awareness

‍What a database is. The difference between a list and a record. What "querying" means. This doesn't require SQL fluency — it requires enough understanding to think clearly about how your product stores and retrieves information.

‍

Security basics

‍What SQL injection is. Why passwords shouldn't be stored in plain text. What HTTPS does. Not because you'll implement security yourself, but because you'll know when to ask whether security has been addressed rather than assuming the AI handled it.

‍

None of this requires a programming course. Most of it can be absorbed through a combination of reading, YouTube, and — yes — asking AI tools to explain things. The investment is weeks, not months, and the return is a meaningfully better experience of building with AI tools.

If you're a founder trying to get a product to market: vibe code the prototype, bring in proper development capability when the hypothesis is validated. The coding question isn't your most pressing problem right now.

If you're a professional trying to stay relevant as AI reshapes the development industry: learn to use AI tools as a multiplier for the technical skills you have. The developers who thrive in an AI-native development environment are the ones who can combine genuine technical understanding with effective AI tool usage — not the ones who outsource their thinking to the AI entirely.

If you're someone considering a career change into tech: the question of "vibe code or learn to code" is a false binary. Learn enough to understand what you're building. Use AI tools to build faster and more. The skills are additive, not competitive.

If you're a non-technical founder who needs to manage a technical team or evaluate technical work: invest in coding literacy. Not developer depth — enough to be an informed technical decision-maker. The returns on that investment compound in every technical conversation you'll have for the next decade.

We're an AI-native development company — which means this question comes up in conversations with founders regularly.

Our honest view: vibe coding is genuinely useful, genuinely limited, and — when used for the right purpose in the right way — entirely compatible with building something real. We've seen founders use it to validate ideas quickly and then work with us to build the production version properly. We've also seen founders mistake the prototype for the product and end up needing a vibe coding cleanup process that costs more to fix than a proper build would have.

The line between those two outcomes isn't the tools. It's the judgment about when "fast and rough" is the right approach and when "built properly" is what the situation requires.

If you're at the point of knowing that what you've built needs to become something more — a production codebase rather than a validated prototype — that's the conversation to have with us.
