Vibe Code Cleanup: What It Is and When You Need It

Michał Nowakowski
|   Updated Sep 27, 2026

Vibe coding means accepting AI-generated code without review. That practice has created a new role: the vibe code cleanup specialist, hired to fix what unreviewed AI output leaves behind. Most developers already draw a clear line here, letting AI assist their work without ever letting it replace their judgment entirely. 

Executive Summary

Skipping code review after AI generates output separates vibe coding from every other way of using AI to write software. AI-assisted development is different. 

Developers use AI for specific tasks while maintaining professional oversight throughout. That gap has created demand for vibe code cleanup work, security fixes, performance repairs, and architectural cleanup of AI-generated code that nobody fully understands. 

Most professional developers avoid pure vibe coding, but many non-technical founders and rushed teams still fall into it. 

When Is Vibe Coding Not Enough?

A first vibe-coded product can feel like real magic. That feeling tends to last right up until something needs to change. One veteran engineer, with close to three decades of experience, built a product almost entirely through AI prompts. He later found he couldn't confidently make a small change to his own creation. Handing 100% of design and development to an AI tool means giving up real control over what gets built.

Software projects carry uncertainty even without AI involved. A small shift in requirements can create engineering challenges nobody predicted during planning. Recent research traces that uncertainty to several sources.

Some comes from misreading what the market wants, some from betting on unproven technology, and some from suppliers and regulators shifting the ground mid-project. Team friction, underestimated budgets, weak testing strategy, and thin documentation all add their own share.

That uncertainty remains even when AI writes code faster. Vibe coding tools let non-technical people go from idea to prototype without touching code. They also let developers move quickly through familiar territory. But a professional reviewing AI output and a founder accepting it blindly are doing two different things. Bridging that difference is exactly what vibe code cleanup specialists get paid to do.

Why Developers Don't Fully Trust AI Coding Tools

The 2025 JetBrains Developer Ecosystem survey covered 24,534 developers across 194 countries. It found that 85% regularly use AI tools, most save meaningful time, and a majority expect AI skills to become a job requirement. Usage isn't the same as blind trust, though. Developers reach for AI mainly on well-defined, lower-risk tasks.

Boilerplate code, looking things up, translating between languages, and summarizing changes top the list. Their hesitation stems from direct experience. AI output varies in quality, struggles with complex logic, raises security concerns, and can quietly erode a developer's skills over time.

The 2025 Stack Overflow Developer Survey goes further. Positive sentiment toward AI tools fell, from around 70% in 2024 to 60% in 2025. Only 3% of developers report high trust in AI output. Roughly a quarter distrust it strongly.

Nearly half consider AI weak at complex tasks, or skip using it for them entirely. Developers resist AI most on the highest-stakes work. About three-quarters won't use it for deployment and monitoring. Roughly seven in ten won't use it for project planning.

Two-thirds cite AI solutions that are "almost right" as their biggest frustration. Nearly half say debugging AI-generated code takes more time than writing it themselves would. So what separates everyday AI use from vibe coding, if most developers already say they avoid it? The two can look similar from the outside. But they aren't the same thing.

Vibe Coding vs. AI-Assisted Coding: What's the Real Difference?

In February 2025, Andrej Karpathy, OpenAI co-founder and former Tesla AI director, described a new way of building software. He called it giving in fully to AI-generated output and no longer engaging with the code itself. The phrase caught on fast. By March, Merriam-Webster had added "vibe coding" as a trending slang term. The jokes about cleanup specialists followed soon after.

Vibe Coding

AI-Assisted Coding

Prompting AI without engaging with the resulting code

Using AI strategically to speed up specific parts of development

Delegating the entire build to AI

Delegating only low-risk tasks, staying in control of planning and architecture

Reasonable for a quick side project or a market-testing prototype

Applicable across the full product design and development process

Simon Willison draws a sharper line than most people. In his view, an AI-written starting point becomes ordinary software development once someone reviews it, tests it properly, and can explain how it works. Skip that step, and it remains vibe coding. Cleanup brings code up to professional standards after the fact. AI-assisted development maintains those standards from the start, using AI to move faster along the way.

What Problems Does Vibe Coding Cause?

AI coding tools hallucinate functions and variables that were never real. They lose track of earlier instructions as projects grow. They reach for the fastest fix more often than the correct one, and routinely assume the happy path, skipping error handling for anything unexpected. 

Security is a particular weak spot. AI-generated code has shipped with open paths to SQL injection, missing input validation, and hardcoded API keys sitting in plain sight. Other vulnerability classes show up too. Databricks' AI Red Team documented two severe cases. The first was a multiplayer game that used Python's pickle module in the network layer, a known vector for arbitrary code execution. The second was a parser for a binary model format, riddled with unchecked buffer reads that could lead to memory corruption.

An August 2025 survey of 18 CTOs found that 16 of them had already dealt with a production incident traced to AI-generated code. Security, clarity, maintainability, and team knowledge were all put at risk. One incident involved a database query that passed every test, then collapsed under real production load because nobody had optimized it for scale. Another involved an authentication module that let deactivated accounts keep reaching admin tools. A third involved a fully AI-built feature that ended up easier to rewrite from scratch than to extend.

AI isn't going away, and it keeps reshaping what a developer's job looks like. As one engineering leader put it, the volume of code now waiting for review has grown far faster than any one person's ability to keep pace with it.

What Do Vibe Code Cleanup Services Do?

Traditional refactoring improves code someone on the team already understands. Developers know the original intent, spot the code smells, and apply fixes as part of the normal cycle. Vibe code cleanup starts from a harder place. It works through code nobody on the current team wrote or fully understands, closer to archaeology than routine maintenance.

One developer offering these services on Fiverr told 404 Media that he'd been doing this work since late 2023, before "vibe coding" was even a term. He'd noticed more teams stuck with AI output that was functional but far from polished. TechCrunch's reporting on the specialty makes a similar point. AI-generated code helps in plenty of situations, but human review has to happen before a business builds anything permanent on it.

One developer TechCrunch interviewed compared fixing vibe-coded work to managing a stubborn teenager's help. Some of what you asked for gets done. Some doesn't.

Unrequested changes show up, and something usually breaks along the way. He still says AI helps him get more done overall. His time now splits roughly in half between writing requirements and everything else, with a smaller slice spent on the actual vibe coding itself.

Vibe Code Cleanup Best Practices

Best practices here are split into what to do before a cleanup engagement starts and what to do once the work is underway. Neither works well without the other. Planning without a systematic process produces inconsistent results, just as a systematic process without planning stalls on an unclear scope.

Chris Rickard, founder at Userdoc, has outlined practical advice for teams navigating AI-assisted workflows:

  • Anticipate the complex problems likely to surface as a project grows.

  • Bring in outside help once in-house AI capacity maxes out.

  • Vet any cleanup specialist on hands-on experience and a track record with similar problems.

  • Run regular audits to catch issues early.

  • Have an escalation plan ready before a crisis forces one into existence.

That advice covers judgment calls, the kind of decisions that depend on context a checklist can't fully capture. Once the engagement is underway, the mechanics of a cleanup follow a more predictable pattern. 

Teams doing this work systematically tend to follow a similar sequence, and understanding what the AI was trying to build always comes first, since every subsequent step depends on getting that right: 

  1. Recognize the pattern the AI was trying to build.

  2. Extract the useful pieces into modular components.

  3. Reformat for readability, and add the validation the AI skipped.

  4. Confirm everything works through thorough testing.

  5. Tune performance once the structure holds.

Purpose-built security scanning has grown alongside vibe coding for exactly this reason. Some tools audit AI-generated code for backdoors and insecure configurations. Others catch vulnerabilities in real time with automatic fixes or enforce quality gates that AI output must clear before release. Monterail's own comparison of AI code review tools walks through how several of these stack up in practice.

Cleanup work has also developed repeatable patterns by language. Converting promise chains to async/await in JavaScript is one common fix. Breaking oversized functions apart in Python is another. Each pattern addresses a specific way AI tends to skip proper error handling or consistent architecture.

Treating cleanup as an ongoing discipline lets a team keep shipping fast without paying for it later.

The Future of Vibe Code Cleanup

Two plausible paths sit ahead. AI could improve fast enough that its output no longer needs cleanup. Or, if capabilities plateau closer to where they sit today, cleanup specialists become a standing part of high-performing product teams.

The more likely outcome is a hybrid already taking shape. AI handles generation, humans handle judgment. AI writes implementations, humans design the systems those implementations live inside. That's a meaningfully different future than the "no engineers needed" story some predicted early on.

Monterail's AI development team can take on a full cleanup if the codebase needs real rework. For a faster gut-check, like a second opinion on one AI-generated feature, get in touch to talk it through directly. 

Key Takeaways

  • The line between vibe coding and AI-assisted coding comes down to review: one skips it entirely, the other builds it in from day one.

  • 16 of 18 CTOs surveyed by FinalRoundAI in 2025 experienced a production incident from AI-generated code, including broken authentication and rebuilding features. 

  • Hallucinated functions, skipped error handling, and serious security gaps show up consistently across independent surveys and incident reports.

  • Vibe code cleanup plays out more like archaeology than refactoring, working through code the current team never wrote and never fully learned.

  • Security scanning tools and repeatable cleanup frameworks have emerged specifically to make this work systematic and predictable.
