The problem with vibe-coding using AI

Cursor and AI feel magical at first — until your project starts falling apart.

AI slowly destroys your architecture

After a few prompts, files end up in random places, patterns are mixed, and the codebase becomes fragile and inconsistent.

Context is lost between sessions

AI forgets why decisions were made. Without a shared source of truth, every new feature risks breaking existing logic.

The project becomes hard to scale or hand off

What started as a fast prototype turns into something no developer wants to maintain, extend, or refactor.

You spend more time fixing AI output than building

Instead of shipping features, you fight regressions, duplicated logic, and broken flows introduced by the AI.

The solution: structure first, AI second

Instead of letting AI guess your architecture, you start with a solid foundation that guides every AI-generated change.

A real production-ready codebase

You start from an opinionated Next.js + Supabase repository with authentication, multi-tenancy, and best practices already in place.

Strict Cursor rules as a single source of truth

Clear, enforceable rules tell Cursor where files live, how features are added, and which patterns must be followed.

PRD generated for AI, not humans

Your product requirements are structured specifically for AI consumption, so context and intent are preserved across sessions.

AI that works inside boundaries, not against them

Cursor accelerates development while respecting architecture, reducing regressions and long-term maintenance costs.

How it works

From idea to a structured, AI-safe codebase in a few simple steps.

01

Describe your idea

Start with a simple description of what you want to build. No technical details required.

02

Get a structured foundation

Receive a production-ready SaaS repository with authentication, tenants, and best practices.

03

Open Cursor and build

Use Cursor with predefined rules that guide AI changes and preserve architecture.

04

Ship without breaking things

Add features confidently, knowing your codebase stays consistent and maintainable.

Why this is different

Most tools help you generate code. This one helps you keep it.

Typical AI tools & boilerplates

  • –Focus on speed, not long-term structure
  • –Architecture is implied or undocumented
  • –AI freely modifies files without boundaries
  • –Context is lost between sessions
  • –Hard to scale or hand off to developers

This foundation

  • Architecture is explicit and enforced
  • Cursor rules act as a living contract
  • PRD is generated for AI, not humans
  • Real production-ready repository
  • AI accelerates without breaking structure

Who this is for

This foundation is designed for people who want speed without chaos.

This is for you if

  • You want to build a real SaaS, not just a demo
  • You use Cursor or AI tools daily to write code
  • You care about structure, maintainability, and scaling
  • You plan to hand the project to developers later
  • You want to move fast without accumulating tech debt

This is not for you if

  • –You expect AI to build the entire product without guidance
  • –You don’t plan to maintain or scale the codebase
  • –You want a no-code or drag-and-drop solution
  • –You are looking for a quick prototype with no structure
  • –You are not comfortable working with code at all

Frequently asked questions

Is this just another boilerplate?

No. This is a full production-ready foundation with enforced architecture, Cursor rules, and AI-oriented PRD. It’s designed to grow with your product, not be thrown away.

Do I need to be an experienced developer?

You should be comfortable working with code and using tools like Cursor. This is not a no-code solution, but you don’t need deep backend expertise to get started.

What happens after I purchase?

After payment, you get instant access to a private GitHub repository with the full source code, setup instructions, and future updates.

Can I use this for commercial projects?

Yes. You can use the foundation to build and sell your own SaaS products without restrictions.

Will this work with Cursor and future AI tools?

Yes. The foundation is built around principles that guide AI safely. Cursor is supported today, and the structure will remain compatible with future AI coding tools.
