What is vibe coding?

The world of software development is undergoing a radical transformation with the emergence of vibe coding, a practice that revolutionizes how developers create applications. This innovative approach, popularized in early 2025 by Andrej Karpathy, former head of AI at Tesla and co-founder of OpenAI, consists of generating functional code simply by using natural language. No more manually writing each line: just describe your intent, and artificial intelligence translates this vision into executable code.

Vibe coding represents a major paradigm shift in the world of programming. Instead of focusing on “how to do it” with precise algorithms and complex data structures, the developer focuses solely on “what to do.” The goal thus becomes to create an environment where AI agents serve as intelligent assistants, automatically producing basic structures and automating repetitive tasks. This method adopts a rapid prototyping mindset where one codes first and refines later.

How vibe coding works

The vibe coding process revolves around a simple yet effective iterative loop. The user begins by describing their objective in a natural language query, such as “create a function that reads a CSV file and extracts email addresses.” The AI agent interprets this request and immediately generates the corresponding initial code.

Next comes the execution and observation phase, where the developer tests the generated code to ensure it works as expected. If the result is not satisfactory or an error appears, new conversational feedback can be provided to refine the code. This loop of description, generation, testing, and refinement continues until a complete and functional code is obtained.

Vibe coding can be applied at two distinct levels. At the micro level, it allows for the refinement of specific code blocks. At the macro level, it concerns the complete lifecycle of an application, from ideation to final deployment. Some developers can thus transform a simple morning idea into a functional prototype by the evening.

Popular vibe coding tools

Several platforms have emerged to facilitate this new development approach. GitHub Copilot is among the pioneers, acting as a true virtual programming assistant directly integrated into code editors. This tool suggests real-time code as soon as context is provided, allowing developers to save valuable time on repetitive tasks.

Replit offers an even more advanced solution with its AI agent capable of building and deploying a complete web application from simple prompts, directly in the browser. Google Cloud has also developed several tools adapted to different user profiles, including AI Studio for beginners, Firebase Studio for full-stack applications, and Gemini Code Assist for experienced developers.

Other platforms like Cursor, Lovable, or Bolt embody this philosophy of “click, describe, and it’s coded.” These environments allow starting from a vision rather than empty files, significantly lowering the initial technical barrier and encouraging creativity.

Advantages and disadvantages of vibe coding

The main advantage of vibe coding lies in its ability to drastically accelerate development. Tasks that previously took days can now be accomplished in a few hours. This speed is particularly valuable for rapid prototyping, allowing startups and teams to test an idea in record time.

Accessibility is another major asset. Vibe coding opens up development to less technical profiles by making application creation more intuitive. AI handles repetitive work while humans retain control of the overall vision and creativity. This approach also encourages exploration and learning by allowing new solutions to be discovered quickly.

However, this method also presents significant limitations. Technical complexity is an issue for real-world applications where requirements can be new or sophisticated. The generated code often requires optimization and adjustment to ensure professional quality. Debugging also becomes more difficult due to the dynamic and sometimes unpredictable nature of AI-produced code.

Security issues associated with vibe coding

Security represents one of the major concerns of vibe coding. Automatically generated code often bypasses traditional reviews and rigorous security controls. Invisible vulnerabilities can thus go unnoticed and be exploited by malicious actors. Without careful human supervision, these flaws remain buried in the code until it’s too late.

Long-term maintenance also raises questions. If the code structure is not properly managed from the start, applications become difficult to maintain and update. Developers then struggle to understand the underlying logic when trying to evolve the project, creating potentially costly technical debt.

Limitations and risks for beginners

Vibe coding presents particular risks for beginner developers. The main danger lies in the overconfidence bias it can generate. Novices quickly achieve results that seem to work, leading them to overestimate their real skills. This illusion of mastery vanishes as soon as a complex bug occurs or when the code needs to be significantly adapted.

Without rigorous prior training, beginners lack the necessary perspective to validate or correct AI productions. They do not possess the basic reflexes to read, understand, debug, and properly design code. This shortcoming can hinder their long-term progression, preventing them from developing the fundamental skills essential for any professional developer.

The solution lies in a balanced approach combining solid training and intelligent use of AI tools. A good grasp of fundamentals in algorithms, data structures, and software architecture allows vibe coding to be used as an accelerator rather than a crutch. A well-trained developer knows where they are going and uses AI as an effective GPS.

Vibe coding to go faster

Vibe coding is establishing itself as a revolution in software development, making application creation faster and more accessible. This approach allows focusing on creative problem-solving rather than tedious manual implementation. However, it does not replace the need for rigorous training and a deep understanding of development principles.

The future belongs to developers capable of combining the best of both worlds: the rigor acquired through classic training and the efficiency brought by vibe coding. Artificial intelligence is a formidable ally for coding faster, but it cannot replace human judgment, creativity, and technical expertise. By maintaining this balanced perspective, vibe coding can truly transform how we build the applications of tomorrow.
