A free guide

Build a real SaaS with AI — and actually secure it.

A start-to-finish guide for non-coders. The same path I used to ship four products: idea, prototype, accounts, payments, launch — plus the security steps almost every AI-built app skips.

Free. One email, the full guide, no spam — unsubscribe anytime.

8 parts ~18,000 words built on 4 shipped products no coding experience needed

Idea to launched, one part at a time.

Every part ends with a checkpoint so you always know it's working before you move on. Written for someone who has never written a line of code.

Most AI-built apps launch wide open. This one won't.

There are plenty of guides that get you a demo. Almost none of them tell you that the same shortcut that made your app appear in an afternoon usually leaves the database readable by anyone and your API keys sitting in the browser.

I know because I built a whole product — Ms. Vibecode — that scans AI-built apps for exactly those holes, after watching them ship over and over. This guide bakes the fix in from the start: every part has a "Lock it down" step, in plain English, that you can actually do yourself.

You come out the other side with something that works and something you'd be comfortable putting your name on.

The security thread, in plain terms

A few of the things you'll actually lock down, no jargon required:

  • Turn on the setting that stops strangers reading your database — and prove it with two accounts.
  • Keep API keys out of the browser and out of your prompts.
  • Take payments without exposing anything you shouldn't.
  • Run an attacker's-eye review before launch, from your own machine.

Start free. Upgrade only if you want more.

The free guide is the whole web-SaaS build — genuinely complete, not a teaser. The Complete Edition is for when you want to go further.

Or I'll build it with you.

You can do all of this yourself — that's the whole point of the guide. But if you'd rather hand off the build, or you're past a web app and need an iOS app or an internal tool, that's what I do: AI in the loop, and someone who knows what "done" actually looks like doing the steering.

Build your idea

You've got the idea and maybe the customers, not the code. I take it from sketch or prototype to a real, shipped product — web or iOS — with working accounts, payments, and data that behaves.

From $1,500

Internal tools & intake systems

The software that quietly runs an operation: intake, cataloging, content management, dashboards. My data-analytics background is built for exactly this — messy inputs in, clean structured records out.

Fix & Finish

Started with AI and stalled short of the finish line? I find what's actually broken, fix the root cause, and ship it — auth, payments, deploys, and a database that isn't wide open.

From $195

No upsell dressed up as advice — if the honest answer is "that's a small fix, don't overpay for it," that's what you'll get. logan@idunnstudio.com

The short answers.

Do I need to know how to code?

No. That's who it's written for. If you can describe what you want and follow steps, you can do this. The AI writes the code; the guide teaches you how to steer it and how to know it's right.

Is it really free?

Yes. The free edition is the complete web-SaaS build — Parts 0 through 8 — in exchange for your email. No trial, no locked chapters in the free download.

What's in the Complete Edition then?

The things that take longest to learn on your own: the full native desktop-app track (shipping a real Mac app), the reference shelf, and the Prompt Pack of 13 copy-paste prompts. It's a one-time purchase, not a subscription.

Who made this?

I'm Logan Gunsch. I run Idunn Studio, an AI-native build studio — web apps, iOS apps, and the internal tools that run a business, built with Claude Cowork and Claude Code. I build with these tools every day, so the guide is what actually worked, including what went wrong. More here.

What happens to my email?

It goes on one list to send you the guide and the occasional useful thing. No spam, unsubscribe anytime. Fittingly, the list is stored the same locked-down way the book teaches — it can't be read with the site's public key.
