The best Facebook Marketplace alert apps, compared

The short answer. Deal Scanner: a phone app for iPhone and Android that watches Facebook Marketplace, OfferUp and Craigslist from one search, needs no Facebook login, puts a Deal Score on each find, and costs $3.99 a month for three searches, cancel anytime. It is built for everyone who checks Marketplace every day, whether flipping is your side thing, your whole job, or not the point at all. Most of the other apps below are priced like business software, for resellers and dealers, from $5 per search to $352 a month. The table has every number, read from each company's own site.

At a glance

Prices and claims are from each company's own website or store listing, read on October 26, 2026. Speeds are what each company advertises, not what we measured. When a company changes a price, this table changes; email the link if you spot one first.

About Deal Scanner's speed. We do not publish a minutes figure because the honest number depends on the marketplace. Facebook, OfferUp and Craigslist each surface a new listing on their own schedule, and no app can see it before the marketplace shows it. Deal Scanner watches continuously and buzzes you when it is posted, and every alert shows when we found it ("Found 2h ago" means we saw it two hours ago), so you always know how fresh it is.

What to look at

• Who it is priced for. Most apps in the table are priced like business software, for resellers and dealers: per-search billing, speed tiers, team plans, six-month commitments. Deal Scanner is priced like an app, for everyone who uses Marketplace: three searches for $3.99, six for $9.99, twelve for $19.99, all three marketplaces on every plan. Only after one thing? Pay for the month you're looking and cancel when you've got it.
• Which marketplaces, from one search. The same couch is on Facebook Marketplace, OfferUp and Craigslist the same afternoon. Deal Scanner watches all three from one search; several apps watch Facebook only.
• Whether it needs your Facebook login. Deal Scanner never asks for one. Several apps in the table do not say.
• Whether it tells you if the price is good. Deal Scanner's Deal Score says how far under the typical price near you a listing sits. Most apps send the listing and leave the judgment to you.
• What the trial costs you. Deal Scanner has no trial; it's $3.99 a month and you cancel anytime. Several apps need a card up front for theirs; one trial is three days.
• How honest the speed claim is. No app can see a listing before the marketplace surfaces it. Deal Scanner stamps every alert with when it found the listing instead of advertising a minutes figure.

Free options, including Facebook's own notifications, are on free Facebook Marketplace alerts.

Why Facebook's own alerts are not enough

Facebook can notify you when a saved search gets new results. Our setup guide shows where the switches are. Three things push people to a separate app:

1. They don't work. Hours late, and they turn themselves off. Facebook does not say how often it re-checks a saved search. In our use the notification lands hours and sometimes a day or more after the listing, and a saved search that worked last week goes quiet this week with no warning. Meta's AI (Meta AI's shopping mode, the Muse agent) can search listings when you ask, in a chat, but nothing stands watch between questions.
2. No negative keywords and no price floor. A saved search for "Herman Miller Aeron" also alerts you to "Aeron-style" chairs and to listings that mention the word in passing.
3. One marketplace. The same couch is on OfferUp and Craigslist too, and those need their own alerts in their own apps.

The apps, one by one

Deal Scanner

One search covers Facebook Marketplace, OfferUp and Craigslist. You set the item, your town, a radius and a price range; it watches with the app closed and buzzes your phone when a listing is posted. Each find gets a Deal Score, how far under the typical price for that item near you it sits, measured from what your search has actually seen. No Facebook login, no account, no commitment. Plans: Casual $3.99 (3 searches), Hunter $9.99 (6), Pro $19.99 (12); yearly plans give two months free. It is built for everyone who checks Marketplace every day, from the person waiting for one truck to the person who flips full time. Details on the Facebook Marketplace alerts page.

Flipify

The widest marketplace list in the group: Facebook, Craigslist, Kijiji, OfferUp, Vinted, eBay, Mercari and Gumtree. Priced per search: $5 a month for a Basic search checked every 10 minutes, $10 for a Premium search checked every minute. Seven-day trial with one of each, card required. iPhone, Android and web. Core alerts work without a Facebook login; an optional auto-messaging feature needs one.

Outpost Alerts

Facebook Marketplace only, and it says so. Basic is $14.99 for one search checked every 30 minutes; Standard $39 for five searches at 3 minutes; Pro $79 for ten searches at 1 minute. Yearly billing takes 20% off. Three-day trial. An iPhone app plus a web app that works on Android in a browser. No Facebook login; it searches from its own servers.

BigFlippa

Facebook Marketplace, Craigslist and OfferUp, with an AI pricing estimate on each listing. $10 a month with 10-minute alerts, $25 with 5-minute, $48 with 2-to-3-minute. Seven-day trial. It is a web app with text, email and push alerts rather than a native phone app.

Crawlbench

Facebook Marketplace only, priced for teams: $39 for 3 searches at 10 minutes, $79 for 8 at 5 minutes, $199 for 20 at 2 minutes, custom above that. A free 24-hour day pass needs no card. Alerts by email, Telegram, Slack, Discord or its phone app. Each alert comes with a comparison to similar nearby listings.

DealHunter

Ten marketplaces: Mercari, eBay, Facebook, Poshmark, Craigslist, OfferUp, Depop, Vinted, Whatnot and AutoTrader, on every plan (AutoTrader added by November 9, 2026). It runs in your browser and installs from its site as a web app. Free plan: one search, paid speed for the first 24 hours, then once-daily checks. Basic $7.99 for 5 searches, Standard $14.99 for 10, Premium $29.99 for 20, each with an hourly alert cap. Seven-day trial on paid plans, card required. Yearly: $69, $129, $249.

DealScout

An iPhone app for Facebook Marketplace alerts, with a Craigslist "scout" added in a recent version. Free plan: one search term, checked hourly. Paid in-app purchases run from a $4.99 single scout to $199.99 for vehicles, with alerts "within 5 minutes" on paid tiers. 4.4 stars from 108 App Store ratings.

Swoopa

Built for vehicle sourcing, usable for anything. Go is $47 a month month-to-month or $28 a month on a 12-month commitment, 7 searches, Facebook Marketplace only, basic alert speed. Turbo ($144, or $99 on six months) and Nitro ($352, or $199 on six months) add the other marketplaces, faster alerts, and AI tools for pricing, scam filtering and VIN detection. Seven-day trial. iPhone and Android.

Flipsentry

Facebook, OfferUp, Craigslist and Kijiji. Starter $34.99 a month for 7 searches checked every 5 to 9 minutes; Hunter $99.99 for 15 searches including one checked every minute; Master $49.99 a week for 22. Seven-day trial, no card. iPhone, Android and web.

CarSnipe

Vehicles on Facebook Marketplace only. $9.99 a month for 2 searches checked every 15 minutes, $24.99 for unlimited searches at 3 minutes. It runs as a Chrome, Edge, Brave or Firefox extension on a computer that stays on and awake, and sends alerts through Telegram. Seven-day trial, card required.

SuperFlip

Facebook Marketplace, with the emphasis on verified sold comps and profit estimates rather than speed: hourly scans on both the free Hobby plan (3 searches) and the $29 Individual plan (10 searches).

Pouncify

A free desktop program for Windows and Apple Silicon Macs, with a companion phone app for the alerts. It is not in the same category as a phone app: the watching runs on the computer, so the moment the laptop sleeps or the PC reboots, nothing is watching. Facebook, Craigslist, OfferUp and Kijiji; one search on the free plan.

Spottable

New, iPhone only, Facebook Marketplace only. Free with hourly checks; a paid tier adds minute-level checks. Too new for us to say more.

Marketplace Monitor and others

Marketplace Monitor is on Google Play and shows up in other people's lists, but we could not find a pricing page on a site of its own to read, so it is not in the table. The same goes for a few browser extensions that come and go. When one publishes prices, we will add it.

Common mistakes when picking an alert app

• Paying per search when you watch four things. $5 a search sounds cheap until the drill, the mower, the truck and the sectional are $20 to $40 a month. Count what you actually watch.
• Believing "instant." No app sees a listing before the marketplace shows it. An app that tells you when it found the listing is being straight with you; one that promises seconds is describing its own timer.
• Handing over your Facebook password. An app that logs in as you can get your account flagged for automation. Prefer one that watches from its own servers.
• Picking a desktop program. The watching stops when the laptop sleeps. The phone is the point.
• Signing a six-month commitment for one purchase. If you need alerts for the month you're looking for a car, pay for a month and cancel.
• Watching a category instead of an item. "Truck" buzzes 80 times a day. "F-150" with a price range buzzes when it matters.

FAQ

What is the best Facebook Marketplace alert app?

Deal Scanner: the lowest-priced paid app in the table at $3.99 a month, three searches across Facebook Marketplace, OfferUp and Craigslist, no Facebook login, a Deal Score on each find, and a native app on iPhone and Android. It is built for everyone who uses Marketplace, whether or not flipping is your job.

Is there a free Facebook Marketplace alert app?

Facebook's own saved-search notifications are free and, in our use, hours to days late. DealHunter, DealScout, SuperFlip and Spottable have free tiers with one to three searches checked hourly or daily. The free desktop programs only watch while a computer stays awake. Deal Scanner is $3.99 a month, cancel anytime.

Do these apps need my Facebook password?

Deal Scanner, Flipify (core alerts) and Outpost Alerts say they do not. CarSnipe runs as you, on your own Android phone or computer. Crawlbench says it never asks for your Facebook login. The rest do not say on their sites, so ask before you sign up.

Which app is fastest?

Several apps advertise a one-minute check on their top plans. Advertised is the key word; no app can show you a listing before the marketplace itself surfaces it, which is why Deal Scanner shows when it found each listing instead of selling a minutes figure.

Do any of them cover OfferUp and Craigslist as well?

Deal Scanner, Flipify, BigFlippa, DealHunter, Swoopa (above the Go plan) and Flipsentry all cover both. Outpost Alerts, Crawlbench, CarSnipe, SuperFlip and Spottable are Facebook only.
