Sound familiar?

  1. Too many options

    You don't know where to start. Some use Claude + n8n, others VS Code, others something else.

  2. Everything breaks

    Claude builds you something nice, and when you change one thing, everything breaks.

  3. Stuck on the basics

    You get stuck for days on login, payments or getting it online.

  4. Afraid to launch

    You're afraid to launch and leak your users' data.

It's not that you don't know how. Nobody showed you the path.

FAQ

Do I need to know how to code?

Basic knowledge helps. Claude writes the code; the kit tells it how.

Does it work on Windows?

Yes. It works on Windows, Mac and Linux.

What exactly do I get?

Access to a private GitHub repository with the kit, the video guide and the updates.

Why a presale?

To build it with the first buyers and shape it around what they need.

Is there a refund?

Yes, if it isn't delivered on the date. Once you get access to the code, there's no refund, because the code is already yours.

Are there extra costs?

The tools it uses have free plans to get started. You need a Claude subscription that includes Claude Code.

Can I use it on client projects?

Yes, as many as you want. What you can't do is resell or share the kit.

Your idea has been on the shelf long enough.
