What is vibe coding #
The term “vibe coding” was coined by Andrej Karpathy — former AI director at Tesla and co-founder of OpenAI — in February 2025. The idea is simple: instead of writing code line by line, you describe in natural language what you want to achieve and let the AI do the work.
In practice, vibe coding covers a broad spectrum:
- Code completion: you write the beginning of a function, the AI completes the rest (e.g., GitHub Copilot)
- Generation from prompts: you describe a feature and the AI generates the entire implementation (e.g., Cursor, Claude Code)
- Conversational development: you dialogue with AI to build an application step by step (e.g., Replit Agent, Claude Code)
- Full generation: you describe an entire application and the AI builds it from scratch (e.g., applications generated via GPT-4, Claude)
This isn’t science fiction: it’s the reality of 2025-2026. And it’s profoundly changing how software is created.
The tools landscape #
Cloud tools (code sent to external servers) #
| Tool | Provider | Model | How it works |
|---|---|---|---|
| GitHub Copilot | Microsoft/OpenAI | GPT-4o, Codex | Integrated in VS Code, completes and generates code |
| Cursor | Cursor Inc. | Claude, GPT-4 | AI-first IDE, dialogue with the codebase |
| Replit Agent | Replit | Various | Conversational development in the browser |
| Claude Code | Anthropic | Claude | Autonomous coding agent in the terminal |
| Windsurf | Codeium | Various | IDE with integrated AI |
Local/private tools (code stays on your computer) #
| Tool | How it works |
|---|---|
| Continue | VS Code/JetBrains plugin, supports local models via Ollama |
| Tabby | Self-hosted code completion server |
| Ollama + coding models | Local Code Llama, DeepSeek Coder, StarCoder2 |
| LM Studio | Interface for local models with OpenAI-compatible API |
The critical difference: with cloud tools, your code is sent to the provider’s servers. With local tools, everything stays on your machine.
Opportunities for businesses #
1. Accelerated prototyping #
AI can generate a working prototype in hours instead of weeks. For SMEs wanting to test an idea before investing, this completely changes the dynamics. An idea that previously required 3-4 weeks of development for an MVP can now be validated in 2-3 days.
2. Reduced development costs #
Data indicates a 30-55% productivity increase for developers using AI tools. For a team of 5 developers, this is equivalent to 1.5-2.7 additional “free” developers. On an annual basis, savings can exceed EUR 100,000-200,000.
3. Internal tools without a full development team #
SMEs often need internal tools — dashboards, automations, integrations — but lack a dedicated development team. With vibe coding, a technically competent employee (not necessarily a programmer) can create useful tools with AI supervision.
4. Democratisation of development #
Vibe coding lowers the barrier to entry for programming. It doesn’t eliminate the need for technical expertise, but it allows people with basic knowledge to contribute to building solutions. This is particularly powerful in SMEs where the budget for developers is limited.
The risks — and they’re concrete #
1. Code quality: 1.7x more critical issues #
Research data shows that AI-generated code has 1.7 times more critical issues than code written by human developers. The code works, passes basic tests, but often hides:
- Anti-patterns: solutions that work but create technical debt
- Duplicated code: AI tends to repeat blocks rather than refactor
- Inadequate error handling: happy-path solutions without exception management
- Ignored scalability: solutions that work for 10 users but collapse at 1,000
2. Security: 2.74x more vulnerabilities #
An even more alarming figure: AI-generated code has a vulnerability rate 2.74 times higher. The AI often generates code that:
- Doesn’t sanitise inputs (SQL injection, XSS)
- Uses outdated libraries with known vulnerabilities
- Implements cryptography incorrectly
- Exposes sensitive information in logs
- Handles authentication superficially
For a business, putting insecure code into production means exposing customers and data to concrete risks.
3. Intellectual property #
When you use GitHub Copilot or Cursor, fragments of your code are sent to the provider’s servers. If your code contains:
- Proprietary algorithms or trade secrets
- Business logic that represents a competitive advantage
- Credentials or access configurations
- Client data hardcoded or in configuration
…you’re potentially exposing your intellectual property to third parties.
4. Tool dependency #
Companies that rely completely on a single AI coding tool risk:
- Lock-in: if the provider changes prices or conditions
- Service interruptions: if the cloud service is unavailable
- Policy changes: if the provider starts using your code for training
How to adopt vibe coding safely #
1. Rigorous code review processes #
AI generates code, but a human must always review it before it goes to production. This is not optional — it’s a security necessity.
Practical rules:
- Every PR with AI-generated code requires review by a senior developer
- Specific focus on security, error handling, and scalability
- No automatic merge of AI-generated code
2. Automated security scanning #
Integrate static analysis tools and vulnerability scanning into the CI/CD pipeline:
- SAST (Static Application Security Testing): analyses source code for vulnerabilities
- Dependency scanning: checks imported libraries for known CVEs
- Secret detection: identifies credentials and API keys in code
The cost is minimal, the benefit is enormous.
3. Private coding AI #
To protect intellectual property, use coding AI models that work locally or on private infrastructure:
- Open source models: Code Llama, DeepSeek Coder, StarCoder2, Qwen2.5-Coder — all work on-premise
- Self-hosted tools: Continue + Ollama, Tabby — code completion without cloud
- PRISMA infrastructure: HTX configures and optimises coding AI models on private infrastructure, with the same functionality as cloud tools but without sending a single line of code externally
4. Rigorous testing standards #
AI-generated code needs more testing, not less:
- Mandatory unit tests: every AI-generated function must have unit tests (which the AI itself can help write)
- Integration tests: verify that AI-generated components work with existing code
- Load tests: validate scalability, not just functionality
- Penetration testing: for code that handles sensitive data or authentication
5. Clear company policy #
Define a policy that specifies:
- Which tools are approved for use in the company
- Which types of code can be generated with AI (and which cannot)
- Which data must never be entered into cloud AI tools
- Who is responsible for reviewing AI-generated code
- How AI use in development is documented
The HTX perspective: private coding AI with PRISMA #
PRISMA also supports the software development use case. HTX configures optimised coding models on private infrastructure:
- Code completion with models like DeepSeek Coder or Qwen2.5-Coder, running on-premise
- AI-assisted code review that knows your codebase
- Automated test generation for existing code
- Automatic code documentation with local AI
The advantage over cloud tools: no line of your code ever leaves your perimeter. Zero intellectual property risk, zero dependency on external services, maximum control.
For SMEs adopting vibe coding, the right approach isn’t “use ChatGPT to write code” — it’s equipping yourself with a secure AI-assisted development environment, with the right quality and security guardrails.
The future of vibe coding #
The trend is clear and irreversible:
- Coding AI models improve every quarter
- Hardware costs for running them locally are decreasing
- Companies that don’t adopt AI for development will lose competitiveness
- Regulation (AI Act) will require transparency and control over AI systems in use
For European businesses, the challenge isn’t whether to adopt vibe coding, but how to do it while protecting intellectual property, security, and regulatory compliance.

FAQ
What is vibe coding?
Vibe coding is an approach to software development where the programmer describes what they want in natural language and the AI generates the code. The term was coined by Andrej Karpathy in 2025. It ranges from simple code completions to entire projects generated by AI with minimal human supervision.
Is AI-generated code secure?
Not automatically. Research shows that AI-generated code has a vulnerability rate 2.74 times higher than manually written code. Human review, automated security scanning, and rigorous testing are always needed before putting AI-generated code into production.
Can I use GitHub Copilot for proprietary business code?
With caution. Copilot sends fragments of your code to GitHub/Microsoft servers to generate suggestions. If your code contains trade secrets or sensitive intellectual property, this represents a risk. Private alternatives exist that work on-premise without sending code to third parties.
Will vibe coding replace programmers?
No, but it will change their role. Programmers will become more like supervisors and architects than authors of every line of code. Code review, software architecture, and problem-solving skills will become even more important. AI is a productivity multiplier, not a replacement.
How can I protect my proprietary code when using AI for development?
The solution is to use coding AI models that run on-premise or on European cloud — such as open source models (Code Llama, DeepSeek Coder, StarCoder) on HTX's PRISMA infrastructure. Your code never leaves your perimeter, eliminating intellectual property risk.
