Let me ask you something.

When you search Facebook Marketplace, how do you do it?

You open the app. You type in a keyword. You scroll. You refresh. Maybe you set up a saved search that sends you a notification six hours after the deal is already gone.

That's how most people do it. And that's why most people miss the best deals.

Facebook Marketplace has over a billion monthly users. When a couch worth $2,000 gets listed for $200 because someone's moving tomorrow, that listing is live for maybe 30 minutes. If you're manually scrolling, you'll never see it.

The people making real money flipping on Marketplace aren't working harder than you. They just have better tools.

So I built one.

I built a Facebook Marketplace Deal Finder. It's an app that scans listings in real time, scores every deal by comparing the asking price against actual market value, and surfaces the best flips automatically.

It filters by category, city, price range, and deal quality. Each listing gets a deal score and an estimated profit. The best opportunities float to the top.

Within minutes of turning it on, it flagged a single listing with over $7,000 in estimated flip profit. A listing most people would've scrolled right past.

The arbitrage on Marketplace isn't the product you're flipping. It's speed.

Whoever sees the deal first wins. This tool makes sure that's you.

This is the part that matters.

I didn't hire a developer. I didn't learn to code. I didn't spend $10K on a freelancer.

I used Claude Code. It's an AI tool that runs in your terminal and builds entire applications from plain English descriptions. You tell it what you want, and it writes the code, runs it, debugs it, and ships it.

The entire app was built in one afternoon.

I recorded the full process and just published the walkthrough. Every step, every prompt, every iteration. Empty folder to working deal finder.

This isn't a "watch me flex" video. It's a build-along tutorial. You can follow the exact same steps and have a working version by tonight.

1. Use it yourself. Find underpriced deals before anyone else. Flip items. Stack cash. You now have an unfair speed advantage over every other buyer on Marketplace.

2. Turn it into a SaaS. There are hundreds of thousands of resellers on Facebook Marketplace. Charge $29/month for access. That's a real recurring revenue business built in a weekend.

3. Sell the tool. Package it as a one-time purchase. Sell it in reseller communities and flipping groups. $97 a pop, sell 100 copies, that's almost $10K from a weekend project.

All three paths start with the same skill: learning how to tell AI what to build. That's what this video teaches you.

I just published the complete step-by-step walkthrough on YouTube.

You'll see the exact prompts I used, how I handled errors, how the deal scoring algorithm works, and how the whole dashboard came together from nothing.

No coding experience required. If you can describe what you want in plain English, you can build this.
