Problems with Vibe-Coded Apps and How to Bring them to Production
Blog
Over the past few years, building software has become dramatically easier. AI coding tools can generate working applications in minutes. Freelancers and offshore developers on platforms like Fiverr or Upwork can assemble prototypes and functional systems at a fraction of the cost of traditional engineering teams.
For many business owners, this feels like a breakthrough. You describe the idea, and the code appears! An application exists. Screens work, data saves, and emails are sent. From the outside, everything seems fine. Until you discover the difference between a prototype and a production-ready system is enormous. In this article, we detail the common misconceptions and problems that arise when you attempt to harden vibe coded apps.
The Rise of “Vibe Coding”
Vibe coding happens when software is created quickly using a mix of AI-generated code, freelance developers, or offshore contractors, and rapid prototyping tools.
The goal isn’t perfection. The goal is momentum. You want something that works well enough to validate an idea, show investors a product, or launch an MVP. And to be fair, this approach works well in the early stages, but it introduces technical debt that many founders are now encountering.
The Prototype Trap
The biggest misconception in modern software development is that if the app works, the architecture must be fine. Unfortunately, that is rarely true. A prototype only needs to work under limited conditions, like small data sets, few users, and minimal integrations.
The MVP works well in controlled environments, but what happens when the app is under pressure?
A production-ready application must be able to survive unpredictable traffic conditions, security threats, constant updates, and deployments. Most AI-generated or freelancer-built applications were never designed for this level of complexity.
Problem #1: Code Quality Issues
One of the first things our experienced engineers notice when reviewing AI-generated code or freelancer-built applications is inconsistent code quality. We find things like inconsistent naming conventions, minimal documentation, duplicated functionality, missing error handling, and the list goes on.
These issues may not break the application immediately, but they make the system increasingly difficult to maintain. Over time, even simple changes become risky, meaning small updates could break other parts, leading to high technical debt and unpredictability.
Problem #2: Fragile Architecture
Another common issue with vibe coded apps is fragile or unstable architecture. In fragile or unstable systems, components that should be independent become tightly coupled. That means a small change in one area can break multiple unrelated features.
For example, a developer updates the email notifications which causes user registration to fail or an API integration to break. This happens when the vibe coded system lacks clear architectural boundaries. Instead of modular services, the application becomes a tangled network of dependencies. Every update becomes a gamble.
Problem #3: Vibe Code and AI-Generated Code Is Hard to Maintain
AI coding tools are powerful, but they often produce code optimized for speed rather than maintainability. Vibe coded and AI-generated apps frequently contain Dead Code or modules that were generated during development but never actually used. These apps often contain redundancies because the developer doesn’t understand the application’s intended use case, so they duplicate features.
Keith Kikta, Head of Engineering Development at Tevpro, says, “We see apps containing multiple email systems, overlapping APIs, and duplicate utility functions. Typically, we end up spending more time understanding it than improving it.”
Problem #4: Scalability Was Never Designed
The biggest issue that arises as the application grows is scalability. Most early-stage developers simply cannot anticipate how your business will use the application in the future. Without that knowledge, it’s extremely difficult to design a scalable architecture.
Common scalability issues include database queries that slow dramatically as data grows and APIs that cannot handle high traffic. What worked perfectly with 50 users may fail with 5,000, and at that point, quick fixes stop working.
The Hidden Cost of Cheap Software Development
This creates a situation many founders eventually face. The early development was inexpensive, but now the vibe coded app is fragile. Every bug fix introduces new bugs. Every feature takes longer to implement. Every deployment feels risky. Should you keep patching this system, or fix the architecture properly?
When It’s Time to Bring in Experienced Engineers
Many businesses reach the same turning point. The prototype works, but scaling it safely requires deeper engineering expertise. This is where experienced software engineering firms become essential.
Tevpro specializes in helping organizations stabilize and scale applications. Rather than discarding the existing system, our goal is typically to audit the codebase, refactor fragile architecture, eliminate redundant systems, implement scalable infrastructure, and prepare the application for real-world production-ready use. The result is software that is reliable, maintainable, and capable of supporting real growth.
