Vibe Coding: How Far Should We Use It? Best Practices, Limits, and Risks

The High Is Real — So Is the Crash

The first time vibe coding really worked for me, it felt unreal.

I described a feature in plain English.
The AI generated most of the code.
I ran it. It worked.

No Stack Overflow. No docs. No context switching. Just flow.

That feeling is powerful — and honestly, a little dangerous.

Because a few weeks later, I trusted that same flow in a real project… and ended up doing a late-night rollback after realizing I’d shipped a subtle security bug.

This post isn’t anti–AI. I still vibe code regularly.
But experience taught me where it helps — and where it absolutely doesn’t.

What Vibe Coding Actually Is

To me, vibe coding is when you stop thinking line-by-line and start coding by intent:

• “Generate a basic CRUD API”
• “Create a settings page with validation”
• “Add auth middleware”
• “Refactor this into something cleaner”

It’s a form of AI-assisted development optimized for momentum and flow.

Why developers love it:

• Faster starts
• Less boilerplate
• Fewer blank screens
• You stay in the problem, not the syntax

Used carefully, it’s a productivity multiplier.
Used blindly, it’s confidence without verification.

Where Vibe Coding Works Really Well ✅

These are places where it has consistently helped me without long-term pain.

Small Apps & MVPs

Early-stage ideas are disposable by design. Vibe coding lets you:

• Validate ideas quickly
• Ship faster
• Kill bad ideas sooner

Perfect use case.

Hackathons & Side Projects

When the goal is learning or demoing, speed matters more than structure. I don’t overthink quality here — I just make sure it runs.

Internal Tools

Admin panels, scripts, dashboards.
If something breaks, the blast radius is small and fixes are fast.

UI Scaffolding & Boilerplate

Forms, tables, layout components, API wrappers — I rarely hand-write these anymore. This is where AI shines.

Where Vibe Coding Starts to Fail ❌

This is where I’ve learned to slow way down.

Large, Long-Lived Systems

Once a codebase has history, shared abstractions, and multiple teams, AI misses context. It doesn’t know why things are weird — only how they look.

Security-Critical Code

Auth, permissions, payments, user data.

This is where secure coding with AI requires real discipline. AI optimizes for “working,” not “safe.”

Complex Business Logic

Anything full of “except when” rules and edge cases tends to break quietly. The code looks clean but fails in reality.

The Mistake That Changed How I Use AI

Here’s the honest lesson.

I once used vibe coding to generate a role-based access layer for an internal SaaS tool. The tests passed. The demo worked. The code looked solid.

What I missed:

• A fallback path defaulted to “allow”
• A missing role check exposed data to the wrong users

Nothing catastrophic happened — but it easily could have.

What I learned:

• AI doesn’t threat-model
• “Looks right” isn’t the same as “is safe”
• Human review isn’t optional for critical paths

Since then, anything auth-related gets slowed down on purpose.

How Much Vibe Coding Is Too Much?

My current rule:

If I can’t explain how this fails, I’m not done.

Healthy vibe coding:

• AI drafts, I refine
• AI suggests, I challenge
• AI accelerates, I own

Unhealthy vibe coding:

• “It works, ship it”
• “The AI probably handled that”
• “We’ll clean it up later”

That’s not speed — that’s deferred risk.

Security Risks I Now Watch Closely 🔐

These show up more often than people admit.

• Insecure defaults (missing validation, auth, rate limits)
• Hardcoded secrets (API keys, tokens, “temporary” creds)
• Risky dependencies (outdated or vulnerable packages)
• Overconfidence in clean-looking code

This is where AI coding risks quietly creep into production.

Best Practices That Actually Help 🛠️

What works for me now:

• Mandatory code reviews for anything non-trivial
• Manual testing — break your own features
• Static analysis and dependency scanning
• Explicit security passes on critical code
• Small commits with clear intent

AI can write code fast. Engineers are still responsible for the outcome.

Final Verdict

I’m not giving up vibe coding.

But I no longer treat it as magic.

Used well, it:

• Speeds up development
• Reduces mental load
• Makes coding more enjoyable

Used carelessly, it:

• Hides complexity
• Creates security debt
• Pushes problems downstream

Vibe coding accelerates — it doesn’t replace engineering.

Experience, not hype, is what teaches you where the line really is.
