The Facebook Marketplace Alerts App That Shows Profit Before You Message
BigFlippa is a Facebook Marketplace alerts app that pings you the moment a deal posts, with a profit estimate on every listing. Try it free for 14 days.
What does a Facebook Marketplace alerts app actually do?
Simple idea. Instead of you refreshing search pages all day, the app does the watching. You tell it what you want in plain English ("road bikes under $150 within 20 miles") and it keeps an eye on Facebook Marketplace and Craigslist for you.
When a listing matches, you get a notification. No scrolling, no missing the good stuff because you were at dinner. The whole point is to be first in the seller's inbox, because on the best deals that is usually who wins.

Why is speed the whole game?
The underpriced listings, the ones actually worth flipping, don't hang around. A well-priced console or couch can pull a dozen messages in the first ten minutes. If you find it an hour later, it's already gone.
So the bottleneck isn't your negotiating chops. It's how fast you learn the listing exists. That's the exact problem an alerts app is built to solve. BigFlippa's typical alert latency is about 5 minutes, which keeps you near the front of the line.
What makes BigFlippa different from a plain alerts app?
Here's the thing. An alert that just says "new listing matched" still leaves you doing homework. Is $120 a good price for that drill? You've got to go check comps, and by then someone else already messaged.
BigFlippa skips that step. Every alert ships with a profit estimate: our read on market value versus the asking price. You glance at it, decide in a second, and either message or move on. We call ourselves an AI sourcing agent for that reason. The alerts are just the delivery method.
- Real-time alerts from Facebook Marketplace and Craigslist
- An upfront profit estimate on every single alert
- Plain-English criteria (we call them radars), no clunky filter menus
- About 5 minutes from post to ping, most of the time
How much does it cost?
BigFlippa is $10 a month. That's it. There's a 14-day free trial up front, so you can watch a couple of radars run before you pay a cent.
Some tools in this space charge quite a bit more, and honestly a few of them have slick features worth the money if you're running a big operation. But for most resellers, cheap alerts plus a profit estimate is the combo that actually moves the needle. No sense paying pro prices to still do the math yourself.
How do you set up your first radar?
Takes about two minutes. You don't need to be technical.
- Pick one category you know well, so you can trust a fair price at a glance
- Type your criteria in plain English, including a strict price ceiling
- Set a search radius that keeps pickups close (travel eats margin fast)
- Turn on notifications and let it run. When a profitable match lands, you'll know
