“Vibe coders can’t make any money.”

That just isn’t true anymore.

AI tools have made it possible to create million-dollar startups as a single person.

Base 44 is proof. One person, Maor Shlomo, scaled to an $80M all-cash exit in just 6 months:

Here’s another person vibe coding to $20K MRR in 50 days.

At this point, if you don’t think you can vibe code to production-ready, you’re really just telling on yourself:

I don’t want you to be in that position. As a PM or founder, you need to know how to use AI tools to build production-ready apps.

Most tutorials cover how to build AI prototypes with tools tools like Bolt and v0. But they completely skip the steps after, taking prototypes to production.

This guide bridges that gap.

We’ll walk through everything from the theory to the tactical steps to take an AI-generated prototype and transform it into software you can actually ship:

  1. What is The Difference Between Prototype and Production

  2. The Fundamental Architecture that Powers Web Apps

  3. The 5 Steps to Build a Production Ready App

  4. Post-Production: Testing, CI/CD, Security

  5. How to Choose an Idea and Grow It


1. What is The Difference Between Prototype and Production

Here’s the brutal truth: that beautiful prototype you built in 10 minutes with Bolt?

It’s about 20% of the way to production. Maybe less.

Here are at least 4 compromises your AI prototype typically makes:

  1. Has no user authentication

  2. Supports limited user flows built for testing

  3. Stores data in browser memory that disappears on refresh

  4. No system design thinking applied to the application or infrastructure - fully vibe-coded

A prototype is built for validation. It answers questions like “Does this solve the problem?” and “Will users understand the interface?” And it’s great for that.

But a production application is built for reliability. It handles real users doing real things with real consequences. It needs:

Prototypes optimize for speed of iteration. Production apps are what you can make money with.


2. The Fundamental Architecture that Powers Web Apps

So if you want to build a production-grade app on your own, you need to build those 7 things. And to do so, you need to understand the fundamental architecture that powers modern web applications.

You probably learned this 10 years ago, so let’s refresh the concepts. Nearly every production app follows the same three-tier pattern:

Tier 1 - Client (Frontend)

This is what users see and interact with. The client runs in the user’s browser and is fundamentally untrusted.

Any code here is visible to users, which is why you never put secrets or sensitive business logic in the client. Any type of validation in the client is for UX, not for security.

Tier 2 - Server (Backend)

The server handles business logic, validates requests, enforces security rules, and coordinates between the client and database.

When a user clicks “Pay Now,” the server validates they’re logged in, checks their permissions, processes the payment with Stripe, updates the database, and sends confirmation emails. This runs on infrastructure you control.

Tier 3 - Database

Your source of truth for all persistent data.

The database is only accessible through the server, never directly from the client. It stores data in tables with columns, rows, relationships, and indexes.

How Frontend, Backend & Database Work Together

So what do we do with this information? Let’s think about building a personal finance transaction. Here’s how the frontend, backend, and database break down:

What do we see here? There’s a fair bit more than just the UI that needs to be built.

So let’s dive into a step-by-step demo to do all of this.

Let’s build a production-ready personal finance tracker together (complete with GIF tutorials to make each step easily replicable).
