Free playbook, worksheet and prompt
I give away the tools. I sell one membership.
Eight free things I built, what each one hands a stranger, and the one paid offer they lead back to. Then a worksheet and a prompt to plan yours in an afternoon.

One paid offer: Agent Ops Club
Dashed: free things that point somewhere else on purpose.
The whole idea, in two lines
The whole idea
OnePick one offer people pay for every month. One you'd happily run for years.
ThenThen vibe code free things that solve its buyer's first problems, and point every one of them at that offer.
That's it. The rest of this page is what it looks like with real tools, and how to plan your own.
Why I'd take this path
Cheap to build is not the same as easy to sell.
Vibe coding made software cheap to build. It didn't make it easy to sell.
So two things happen a lot. An app ships and nobody uses it. Or the builder turns into an agency, chasing one client at a time and starting from zero every month.
A recurring offer fixes the second problem. Free software fixes the first.
People try a free tool that works today. They star a repo. They share a page that helped them. That's traffic, trust and an email list you didn't buy, and all of it lands in one place.
My map
Eight free things, one offer.
My one offer is the Agent Ops Club, a membership for people who set up AI employees for businesses and want their first client. Everything below is free. Each one lives where a stranger can find it, and each one has a single door back.

What it hands you
The day one SEO setup for a vibe coded React app.
Free thing number nine is the page you're reading.
What the first five have in common
Three things. I'd copy all three.
01
They solve the buyer's first week.
Someone who joins to set up AI employees for clients needs the employees. They need to know which job to sell first. They need their agent signed into the right sites without pasting passwords. And they need API keys to stay out of their chat history.
That's the AI Employees, the Scan, Cookie Sync and Safe Keys, in that order. Each one is a problem they'd hit before they ever pay me.
02
They're real software, not an ebook.
A repo you can clone. An extension you can load. A scan that runs on your own site right now.
People share things that work. Nobody shares a PDF.
03
Each one has one door.
The code is public. The page next to it does the explaining. The free account gets the extra piece: the setup steps in your inbox, the full report, the kit as a zip.
One door, not five. And the free thing never has to pitch. The page and the account do that part.
The two that don't fit
And why I kept them anyway.
Nano Banana Editor pulls in image makers. The SEO guide pulls in app builders. Great people, but not who joins a club for selling AI employees.
So I don't force the pitch. Both point at my free community instead, where vibe coders of every kind hang out.
If your most popular free thing attracts a different crowd than your offer, give it a different door. Don't bolt your offer onto it.
Pick your one offer
Four questions. Any no, pick again.
Would you still want to run it in three years?
You'll be making free things for it for a long time. Caring about the topic is what keeps you shipping when a launch goes quiet.
Does it renew?
A membership, a SaaS, a retainer, a paid community. One-off sales mean starting over every month.
Can you name the buyer in five words?
"People selling AI setups to businesses." "Etsy sellers with big catalogs." If you can't name them, you can't build for their first week.
Can software fix the buyer's first problems?
If those problems are all human (trust, a call, a contract), free tools won't move much. Pick an offer whose buyer has problems a tool can fix.
Plan three free things for it
Five steps, one afternoon.
Step 1 of 5
List the buyer's first week.
Write down the first ten problems your buyer hits in week one. Not the big promise. The small annoying stuff before it.
Step 2 of 5
Keep the weekend builds.
Cross out anything you can't vibe code in a weekend. You want three you can ship this month.
Step 3 of 5
Pick a format for each.
A free tool in the browser, an open-source repo, a Chrome extension, a template, a prompt kit. Working tools beat documents.
Step 4 of 5
Give each one a home.
A page on your own site with the thing, a short explanation, and one door to your offer.
Step 5 of 5
Ship one. Post it. Then the next.
One a week is plenty.
Mistakes I'd skip
Four ways a free thing feeds nothing.
Gating the free thing before it works.
My Cookie Sync code is public on GitHub. The free account gets the steps and the prompts, not permission to see the code.
Pitching in the post.
The post hands over the thing. The page does the selling.
A free thing with no door.
A repo with no link back is a gift with no card.
Building for applause.
Stars feel great. A free tool that fixes your buyer's problem beats a viral one that fixes someone else's.
The prompt
Let your AI chat interview you.
Paste this into Claude, ChatGPT or whichever chat you use. It asks one question at a time, then writes the plan.
You're my offer strategist. Help me pick ONE recurring offer and plan three free lead magnets I can vibe code for it. Ask me one question at a time and wait for my answer before the next one.
1. Interview me, eight questions at most: what I've built or sold before, what I could happily work on for years, who I like helping, and what I can build with my tools (vibe coding apps like Lovable, Bolt, Cursor, the Claude desktop app or Codex).
2. Propose three candidate offers that renew: a membership, a SaaS, a retainer service or a paid community. For each one, name the buyer in five words, the price model, and five problems that buyer hits in their first week.
3. Score all three on four yes/no tests: I'd still run it in three years; it renews; I can name the buyer in five words; software can fix the buyer's first problems. Recommend one, and say plainly why the other two lost.
4. For the winner, list ten first-week problems of the buyer. Pick the three I could build in a weekend each, as working things (a browser tool, an open-source repo, a Chrome extension, a template or a prompt kit). No ebooks, no PDFs.
5. For each of the three, give me: a name, what it does in one line, who grabs it, where it lives (a page on my site, GitHub, the Chrome Web Store), the one door back to my offer, and what a free account gets that the public version doesn't.
6. Give me a four-week plan: one lead magnet a week, and week four also ships the offer's own page. For each lead magnet, write the first social post's opening line (12 words or fewer, naming the thing) and a close the reader can do in one tap.
7. Finish with a build prompt for lead magnet number one that I can paste straight into my vibe coding app.
Rules: be blunt. No hype words. If my idea fails a test, say so. Never invent numbers about my audience or my results; ask me instead.
Here's a worked example of the shape, so you know what good looks like. Offer: a membership for people who set up AI employees for businesses. Free things: open-source AI employee roles (the software they'd install for a client), a website scan that names the first job to hand to AI (how they find what to sell), a Chrome extension that lets an agent use signed-in sites without passwords, and a mod that keeps pasted API keys out of the chat. Each lives on its own page, and a free account gets the setup steps.The worksheet
