The Limitations of Vibe Coding: What You Need to Know

An honest assessment of vibe coding drawbacks, security risks, and when to consider more reliable alternatives for your app development

Timothy Lindblom

Founder, Natively

Understanding what are the limitations of vibe coding is essential for anyone considering this AI-driven approach to software development. While vibe coding has captured attention for its promise of rapid app creation, the reality is more nuanced. Research from arXiv and academic institutions reveals that 40-62% of AI-generated code contains security vulnerabilities, and developers are spending more time debugging than they would writing code themselves. This guide provides a comprehensive look at the real drawbacks and helps you make informed decisions.

Key Takeaways

  • Security vulnerabilities are prevalent — 45% of AI-generated code contains security flaws according to Veracode research
  • Code quality suffers — vibe-coded projects accumulate technical debt 3x faster than traditionally developed software
  • Debugging becomes exponentially harder — developers report spending 63% more time fixing AI-generated bugs
  • Enterprise adoption is limited — only 28% of healthcare and 34% of financial services companies use vibe coding
  • Alternatives exist — platforms like Natively combine AI assistance with production-ready code standards

What is Vibe Coding?

Vibe coding is a term coined by Andrej Karpathy, co-founder of OpenAI, in February 2025. He described it as a development approach where you "fully give in to the vibes, embrace exponentials, and forget that the code even exists." The defining characteristic is accepting AI-generated code without fully understanding or reviewing it.

"Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial."

— Simon Willison, creator of Datasette, via simonwillison.net

As Stack Overflow reported, the approach may work for "throwaway weekend projects" but poses significant risks for anything beyond that. The key distinction from AI-assisted coding is the lack of human review—if you understand and verify all AI-generated code, that is not vibe coding.

Security Vulnerabilities: The Critical Risk

Perhaps the most significant limitation of vibe coding is the prevalence of security vulnerabilities in AI-generated code. According to research from Kaspersky and multiple academic studies, AI models trained on public repositories reproduce both good practices and widespread vulnerabilities.

Common Security Issues

  • Hardcoded credentials and API keys
  • Weak authentication logic
  • Improper input validation
  • Deprecated security libraries
  • Wildcard IAM permissions

AI Package Hallucination Risk

A unique danger is AI package hallucination—when AI suggests non-existent libraries. Attackers monitor these hallucinations and register malicious packages with the suggested names on NPM or PyPI.

When developers run npm install on hallucinated packages, they unknowingly install malware.

Code Quality and Technical Debt

Beyond security, vibe coding creates significant code quality challenges. As noted by LeadDev, AI-generated code often lacks the structure, documentation, and clarity necessary for long-term maintenance.

Key Code Quality Problems

  • 1
    Inconsistent Patterns

    AI generates solutions based on different prompts without a unified architectural vision, creating patchwork codebases.

  • 2
    Missing Documentation

    Documentation becomes sparse or nonexistent, making future modifications significantly more difficult.

  • 3
    Code Bloat

    Vibe-generated code tends to be much longer than human-written code. As one programmer noted: "Create 20,000 lines in 20 minutes, spend 2 years debugging."

  • 4
    Business Logic Gaps

    AI-generated code is prone to business logic vulnerabilities—it lacks the "common sense" that human developers bring to understanding workflows.

Scalability and Enterprise Challenges

According to TATEEDA and enterprise research, vibe coding faces significant scalability limitations that make it unsuitable for growing applications.

Scalability Problems

  • Database query optimization frequently overlooked
  • Monolithic architecture tendencies
  • Performance degradation as data grows
  • Limited ability to scale components independently

Enterprise Adoption Rates

  • 73%Tech startups
  • 61%Digital agencies
  • 34%Financial services
  • 28%Healthcare

The Enterprise Reality

Raymond Kok, CEO at Mendix, summarizes the enterprise perspective: "While vibe coding is fast and creative, it is deeply unreliable for enterprise use."

Industries with stricter regulatory requirements—healthcare, finance, logistics—have technical, organizational, and legal constraints that AI assistants are unaware of. This "missing depth" means compliance requirements for personal, medical, and financial data are not reflected in AI-generated code.

Debugging and Maintenance Challenges

One of the most practical limitations of vibe coding is the debugging nightmare it creates. According to the State of Software Delivery 2025 report, the majority of developers spend more time debugging AI-generated code than they would have spent writing it themselves.

Why Debugging is Harder

The "Shadow Bug" Problem

AI code that looks perfect but contains deep, structural vulnerabilities that are extremely difficult to identify and fix.

Context Window Limitations

LLMs struggle to parse large codebases and are prone to forgetting what they are doing on longer tasks, as reported by MIT Technology Review.

Lack of Understanding

By definition, vibe coding means accepting code without understanding it—making it nearly impossible to debug when issues arise.

When You Should Not Use Vibe Coding

Based on the evidence and expert opinions, there are clear scenarios where vibe coding should be avoided entirely.

Never Use Vibe Coding For

  • Production or enterprise applications
  • Healthcare systems (HIPAA compliance)
  • Financial services (PCI-DSS, SOX)
  • Projects requiring long-term maintenance
  • Security-sensitive applications
  • Code you cannot review and understand

Acceptable Use Cases

  • Throwaway weekend projects
  • Rapid prototyping and concept validation
  • Learning and experimentation
  • Internal tools with no sensitive data
  • Personal projects without users
