Why You Can’t Build a Real SaaS Just by “Vibe Coding”

posted 2 min read

Lessons from 10+ Apps

Over the past year, I’ve built more than 10 projects using rapid prototyping tools like bolt.new and lovable, and launched two full-scale SaaS products:

  • LinkTrim.in – a modern URL shortener
  • PersonaCraft.app – your audience intelligence and builder tool

There’s no doubt: AI radically accelerated my development cycles.
UI scaffolding, dummy flows, quick iterations — all of that became 5× faster.
It felt like having a hyper-efficient assistant that could instantly sketch out your rough draft.


The Problem with “Vibe Coding”

When you’re building in the “vibe” —

Quickly generating code, skipping planning, and following intuition over structure —
it’s easy to create a slick-looking MVP.

But the moment you move beyond the demo phase and start implementing core features like:

  • ✅ Authentication flows
  • Onboarding logic
  • Billing and subscription handling
  • Usage metering
  • Role-based permissions

…it all starts to fall apart.

  • The AI-generated code becomes fragile
  • Components don’t communicate cleanly
  • Flows aren’t built for edge cases or real user behavior
  • You spend more time debugging or rewriting logic than if you had done it right the first time

In short: the speed advantage vanishes once you need stability and scalability.


AI is a Multiplier — Not a Co-Founder

AI can drastically speed up workflows — if you already know what you're building.
But it does not replace:

  • System thinking
  • Product strategy
  • ️ Architectural planning

It won’t make key decisions for you.
It won’t create well-structured flows or scalable logic.
And it definitely won’t hold up under production complexity.

That’s where tools like PersonaCraft.app and LinkTrim.in come into play.
They’ve helped me shift from just building fast to building intentionally:

  • Focused on real users
  • Designed around real growth loops
  • Structured for long-term scale

Not just “vibing” — but building with purpose.


What I’ve Learned

  • ⚡ AI is best used to accelerate the boring stuff, not to skip the hard stuff
  • Vibe coding is fun, but fragile — it gets you started, not finished
  • Real SaaS products need intentional architecture from the start — especially when users, revenue, and scale are involved

Let’s Talk

I’m curious to hear from others building with AI and rapid prototyping tools:

Have you hit the same wall with vibe-coded apps? How did you overcome it?
Let’s make the conversation more than just vibes.
