The operations manager at a metalworking company in Valencia has had the same problem for months: his team records production incidents in a shared spreadsheet that keeps corrupting, that nobody updates consistently, and that produces no useful reports. Commissioning a custom tool from a software provider means months of waiting and a budget that has not been approved. A year ago, there was no alternative. Today he describes what he needs in plain language and has a working prototype by Friday.

That is Vibe Coding. This article explains exactly what it is, how the real workflow operates, how it differs from existing alternatives, which tools make it possible, which use cases make most sense for an industrial company in Spain and, above all, what concrete risks exist when it is applied without adequate technical supervision.

What is Vibe Coding: programming by talking to an AI

The origin of the term: Andrej Karpathy and the phrase that changed the industry

The term was coined in February 2025 by Andrej Karpathy, co-founder of OpenAI and former Director of AI at Tesla. He described it as a style of programming where the developer “fully gives in to the vibes, embraces the exponentials and forgets that the code exists”. Behind the casual framing lies a technically precise idea: instead of writing code, you describe in plain language what you want the software to do, and an AI tool generates it.

Collins Dictionary named “Vibe Coding” its Word of the Year 2025. In 2026, 41% of all code written worldwide is now generated by AI. This is not an emerging trend: it is the new normal of software development.

The definition that works for someone who is not a programmer

Vibe Coding is the practice of creating functional software using natural language instructions, without manually writing code. The AI interprets what is described, generates the corresponding code and the result is tested directly. If something does not work as expected, the adjustment is described. The cycle repeats until the result is correct.

What can be built with this process is concrete:

• Web applications,
• Internal management tools,
• Tracking dashboards,
• Forms connected to databases,
• Product landing pages,
• Administrative process automations.

If it can be described clearly, AI can attempt to build it.

How Vibe Coding works in practice: the four-step cycle

Step 1 — Describe: turning a business need into a precise prompt

The starting point is not the tool: it is clarity about what is needed. An effective prompt is not “build an app for the company”. It is: “I want a web tool where the production team can log incidents with date, shift, defect type and an attached photo, and where the quality manager can view a dashboard with the last 30 days of records filtered by defect type.” The more precision in the input, the more useful the output.

Step 2 — Generate and test: the AI builds, the team evaluates

With the prompt defined, the tool generates the code and, in many cases, deploys the application in a test environment accessible from the browser. That the app works technically does not mean it solves the problem it was created for. That judgement is exclusively human, and it determines the real value of the output.

Steps 3 and 4 — Iterate and decide when to involve an expert

If something is wrong, the problem is described in plain language and the AI corrects it. That iteration cycle is fast. But there is a point at which informal iteration is no longer sufficient: when the tool will handle real customer or employee data, when it will integrate with existing systems, or when it will be used in production continuously. At that point, technical review by a specialist turns the prototype into a sustainable business asset.

Vibe Coding vs. No-Code vs. Low-Code vs. traditional programming

The comparison table every manager should read before making a decision

The advantage that sets Vibe Coding apart from every alternative: you own the code

The critical difference from classic No-Code platforms —Bubble, Webflow, Glide— is that Vibe Coding generates real, portable code. There is no dependency on the platform provider existing tomorrow, no limitations imposed by a visual interface, and if the project grows or requires specialist maintenance, the code can be handed over to a developer. That portability is what makes Vibe Coding an investment rather than a dependency.

When it makes sense and when it does not

Makes sense: rapid prototypes, low-risk internal tools, product landing pages, administrative process automations, idea validation applications.

Does not make sense without expert technical review: systems handling personal customer data, applications integrated with the company’s ERP or CRM, software operating in critical production processes, or any development intended to be maintained for years.

The most relevant Vibe Coding tools for companies in 2026

For companies without a technical profile: Lovable, Bolt and v0

Lovable is the most non-technical-user-friendly option: it generates a complete full-stack application from a prompt and deploys it automatically. A freelancer would charge between €1,500 and €3,000 for a landing page that Lovable can deliver in an afternoon for approximately €25/month. Bolt offers greater control over the stack with an equally accessible learning curve. v0 by Vercel stands out for high-quality React visual interfaces.

For companies with some technical capacity: Cursor and Claude Code

Cursor (~$20/month) is the highest-rated AI IDE when there is an internal developer or external technical consultant involved. It preserves full code ownership and allows reviewing every change before applying it. Claude Code by Anthropic excels at complex terminal tasks and larger-scale projects.

How to choose: the question that replaces the feature-comparison table

Who is going to review and maintain what gets generated? If the answer is “nobody with technical training”, the right tool is the most accessible one (Lovable, Bolt) and the scope should be limited to prototypes and low-risk internal tools. If there is someone with technical judgement in the process, the scope widens and the result can reach production with confidence.

What Vibe Coding can do for an industrial company in Spain: real use cases

Custom internal tools without waiting for an external provider

With Vibe Coding, an operations manager who is clear about what they need can have a working prototype in days, without a provider budget and without months of waiting. For a deeper look at this use case, see the article Vibe Coding for teams: how to create custom internal applications.

Websites, landing pages and commercial automations

A landing page for a trade fair, a product page for a new manufacturing line, a lead capture form connected to the CRM: all of this can be produced in hours. The full detail is in the article Vibe Coding for websites and B2B landing pages. For process automations, combining Vibe Coding with Make or n8n allows chaining complete flows without code.

The real risks of Vibe Coding that no tutorial ever mentions

45% of AI-generated code contains security flaws

According to the Veracode GenAI Code Security Report 2025 and Builder.io data from May 2026, 45% of AI-generated code contains security flaws in production. AI-generated pull requests have 2.74 times more vulnerabilities than those written by humans. AI models optimise for code that works, not for code that is secure.

Black-box technical debt: code that works today and cannot be maintained tomorrow

Refactoring fell by 60% in projects with intensive Vibe Coding, accumulating what experts call “black-box technical debt”: code that works in demos but whose internal logic is opaque even to those who supervised it. Dev.to reported an 8x increase in code duplication due to loss of context between sessions.

GDPR and corporate data: the responsibility that does not disappear

Article 30 of the GDPR requires documenting all personal data processing activities. That obligation falls on the company, not on the AI tool that generated the code. A Vibe Coding application that processes customer data is a data processing activity. Non-compliance can result in fines of up to 4% of global turnover.

The speed paradox: generating errors at scale is also faster

66% of developers report that AI-generated code requires significant corrections before it can be used in production (Stack Overflow Developer Survey 2026). Vibe Coding amplifies what is already working well and also what is already going wrong. The cost of post-deployment correction is always higher than prior technical review.

The right model: Vibe Coding as accelerator with technical supervision as guarantee

What AI can decide and what always needs expert validation

AI can generate the first prototype, iterate on it and propose variants. What it cannot do is evaluate whether the architecture is adequate for the data volume it will process, verify that access controls are correct, guarantee GDPR compliance, or decide when something is ready for production. Those decisions always require a person with real technical judgement.

Why the difference between a prototype and a business asset is always a person

At Smart Team we work with industrial B2B companies in Spain that want to incorporate Vibe Coding in a way that generates real commercial results. What we bring is not access to tools —those are accessible to anyone— but the strategic judgement to decide what to build, the technical expertise to validate what is generated before deploying it, and accountability for the outcome. AI lowers the barrier to entry. Expertise determines whether what is built is an asset or a liability.

Frequently asked questions about Vibe Coding for industrial B2B companies

Do you need to know how to code to use Vibe Coding in a company?
No. The most accessible tools —Lovable, Bolt, v0— are designed for users with no technical background. For applications going into production or handling sensitive data, review by someone with technical training remains essential.

Is Vibe Coding safe for tools that handle customer data?
Not without prior technical review. 45% of AI-generated code contains security flaws that are not visible in normal operation. For any tool processing personal data, a technical security audit and GDPR compliance check are mandatory, regardless of how the code was generated.

How much does it cost to implement Vibe Coding in a Spanish industrial SME?
Access tools are affordable: Lovable from ~€25/month, Bolt with a free plan available, Cursor Pro at ~€18/month. The real cost lies in technical supervision. For short-term results, working with a specialist team for initial configuration and validation is the most cost-effective option.

What is the difference between Vibe Coding and hiring a developer?
A developer brings technical expertise, architectural judgement and responsibility for what they build. Vibe Coding offers prototyping speed and accessibility. The most effective model for an industrial SME combines both: Vibe Coding to validate ideas quickly, a developer or technical consultant to ensure production quality.

Can Vibe Coding-generated code be used in production without technical review?
For simple, low-risk internal tools, yes — with caution. For any application that processes third-party data or integrates with existing systems, no. 66% of AI code requires significant corrections before production. Prior technical review is always cheaper than post-incident correction.
