In Plain Terms
Vibe coding, a term popularized in 2025, describes building software by prompting an AI tool in natural language and accepting its generated code with minimal manual editing — tools like Lovable, Bolt and Replit's AI features are built around this workflow, aimed at both non-developers and developers moving fast.
What It's Genuinely Good For
Throwaway prototypes, internal tools with low stakes, and getting a rough version of an idea in front of real users fast enough to know whether it's worth building properly. For that use case it's a genuine, significant speed-up over building everything by hand.
Where It Breaks Down
Generated code that nobody reviews line-by-line tends to accumulate the same categories of problems: security gaps (auth, input validation), fragile handling of edge cases the prompt never described, and architecture that works for the demo but doesn't hold up under real traffic or real data. None of that shows up in a quick demo — it shows up in production, later, at a worse time to fix it.
The Practical Middle Ground
AI-accelerated development, as distinct from vibe coding, uses the same speed for scaffolding and boilerplate while keeping architecture, security and integration decisions under actual engineering review — which is the difference between a fast prototype and a fast, still-reliable production build.
