Swoopa vs Marketplace Monitor: Which Alert App Is Worth Paying For?

Swoopa, Marketplace Monitor and Outpost Alerts at a glance

Every row comes from each company’s own public pages, checked 20 October 2026. Nothing here reflects hands-on testing of Swoopa or Marketplace Monitor.

If you only want the two-way answer: Marketplace Monitor is the cheaper way to watch one search, and Swoopa is the cheaper way to watch many. The detail behind that follows.

Pricing, plan by plan

The two companies price in opposite directions. Swoopa bundles a lot of searches into each plan and discounts heavily for a 6 or 12 month commitment. Marketplace Monitor bills by the month and sells only one to five searches per plan, with speed as the main thing that rises with price.

Per search, the gap is wide. Swoopa Go works out at $4 a search on the yearly commitment, or about $6.71 month to month. Marketplace Monitor’s plans run from $15 a search on Intermediate to $34 on Expert Plus+. If you want to watch seven different things at once, Marketplace Monitor’s fixed plans cannot do it at all: they stop at five searches.

Marketplace Monitor also has a custom-package calculator where you pick marketplaces, one to five keywords, a find time from instant to 10 minutes and a monitoring window of 12, 15, 18 or 24 hours a day. On 20 October 2026 it showed no price for any combination, so custom packages are left out of the comparison. Its pricing page also advertised a “30% off” code at checkout with no terms given.

Swoopa’s committed prices carry the usual catch: the cheapest way in is $336 paid against a plan you have tried for a week. The full breakdown of what each tier adds is in the Swoopa review.

How each one describes its speed

Speed is what you are paying for, and the two vendors describe it in ways that cannot be compared directly.

• Swoopa uses labels. Its plans are Basic, Fast and Instant, with no interval in minutes for any of them. Its homepage adds that the speed applies to results within 100 km of your selected location and to exact keyword matches. Its iPhone app listing goes further and says it scans “every second”, but no plan on the pricing page states a figure.
• Marketplace Monitor uses average find times. Five minutes on Starter, three on Intermediate, two on Expert, “instant” on Expert Plus+. The page says the average “can be faster and slower”, so a 5-minute average will include alerts that arrive well after five minutes.

Marketplace Monitor deserves credit for putting numbers on its tiers at all; not every alert tool does. The weakness of an average is that it tells you nothing about the slow tail, and the slow tail is where you lose listings. Swoopa’s labels tell you even less, so the only way to judge either one is to run the trial on a search you know and note how long after posting each alert arrives.

Either way, the fastest tier is expensive. Instant on Swoopa is $199 a month on a six-month commitment ($352 without one). Instant on Marketplace Monitor is $169.99 a month for five searches.

Marketplaces, apps and who each is built for

Both tools sell themselves on covering more than Facebook, but the detail differs.

• Swoopa lists Facebook Marketplace, OfferUp, Craigslist, eBay, Gumtree, Kijiji and Nextdoor. Go, the entry plan, is Facebook only; Turbo and Nitro open the rest. It runs as iOS and Android apps, with email notifications for people on a desktop. Its homepage now leads with private-party vehicle listings and a car dealership programme, and its extras (AI valuations, price-drop alerts and VIN and title detection on Nitro) lean the same way.
• Marketplace Monitor lists Facebook, Gumtree, Craigslist, OfferUp, eBay and Kijiji as supported, and its calculator also offers Depop, Vinted and Shpock. Its four fixed plans are labelled as Facebook Marketplace packages, so the other marketplaces come through custom packages whose prices were not shown. It has iOS and Android apps and a desktop version, sends push notifications, and puts a dedicated account manager and spam filtering on every plan. Its calculator offers US dollars or British pounds.

Swoopa vs Swoopa Dealers. Autocomplete shows people comparing these too. Swoopa Dealers is a separate iPhone app from the same company, Market Sourcing Solutions Pty Ltd. Its App Store listing says it is built for car dealerships that buy from private sellers every week and that it is “not a consumer flipping tool”. If you are buying for yourself, the ordinary Swoopa app is the one the pricing above applies to.

On the App Store on 20 October 2026, Swoopa had 4.4 stars from 552 US ratings and Marketplace Monitor 3.4 stars from 75. Ratings say little about alert speed, but they are a public view of how each app’s users rate it.

If the other marketplaces matter to you, check what each one offers on its own first: the marketplaces with built-in saved search alerts include eBay, Gumtree and Craigslist, free.

Who each one suits

Taken from their own pages, each tool fits a fairly specific buyer.

Notice what is missing: the buyer who sources on Facebook Marketplace, wants several searches, wants to know how often they are checked, and does not want a contract. Neither tool is priced for that person, and that is a large share of the people searching for both of them.

Why the check interval decides who gets the listing

Strip away the plan names and both tools are selling the same thing: being in the seller’s inbox before the queue forms.

A well-priced listing on Marketplace follows a predictable pattern. It goes up because the seller wants it gone this week. The first message arrives within minutes, a few more follow, and within the hour it is often marked pending. A buyer who sees it at lunchtime, three hours later, sees a listing that has already been sold in all but name.

You cannot beat that by refreshing the app. Checking ten times a day still leaves gaps far longer than a good listing’s useful life, and nobody keeps it up for a month. Facebook’s own saved searches do not say how often they run and behave differently from account to account, so they do not close the gap either.

That is why the speed column matters more than the marketplace list or the AI extras. A five-minute average is fine for a slow category and loses you the fast ones. A label with no number gives you nothing to plan around. What you want is a stated interval on the search that matters most to you, at a price you will still pay in month seven.

Where Outpost Alerts fits

Outpost Alerts is an Australian-built service that watches Facebook Marketplace for new listings matching your keywords and sends them to an iPhone app, a web dashboard or Discord. It covers one marketplace, and it publishes how often it looks.

Outpost prices are in US dollars from its pricing page on 20 October 2026, or 20% less billed yearly; in the iPhone app the App Store sets the price in your local currency. Note that the speed rows measure different things: Outpost states how often your fastest watchlist is checked, Marketplace Monitor states an average find time, and Swoopa states a label.

The case for Outpost rests on three things. Speed for the money: a one-minute check on your fastest watchlist costs $79 a month with no contract, against $169.99 for Marketplace Monitor’s instant tier and $199 committed for Swoopa’s. Standard at $39 gives five watchlists with the fastest checked every three minutes, the same number of searches as Marketplace Monitor’s $99.99 Expert plan. Relevance filtering: a keyword match is not the same as the item you wanted, and across 30,777 keyword-matching listings Outpost discarded 38.6% as not the item searched for (18,890 kept, 11,887 rejected). You also set include and exclude words, a price range, and one location with a 5-500 km radius per watchlist. Delivery: push alerts in the iPhone app, one web feed, or a Discord channel your buying partner also reads, with no Facebook login because Outpost searches Marketplace from its own servers.

What Outpost does not do matters just as much. It watches Facebook Marketplace only: no Craigslist, OfferUp, Gumtree, Kijiji or eBay. It has no free plan, no Android app (Android users use the web app), no price-drop alerts, no VIN checks and no resale valuation, and its trial is 3 days rather than 7. If you buy across several marketplaces every week, Swoopa or a Marketplace Monitor custom package covers ground Outpost does not.

The verdict

Between the two, Marketplace Monitor is the better buy if you watch one or two things and want a stated speed without a contract, and Swoopa is the better buy if you run many searches, buy cars, or need Craigslist, OfferUp and Kijiji at a published price. Both keep their “instant” tier for plans that cost $169.99 to $352 a month.

For buyers who source on Facebook Marketplace, Outpost Alerts is the better choice than either. It is the cheapest way in at $14.99, needs no contract, puts a published one-minute check on your fastest watchlist at $79, gives ten watchlists on that plan, and filters out listings that only share a word with your search. Run the trial on the search you care about most and note how early each alert arrives.

For the wider field, the comparison of every major Marketplace alert app puts Flipify, CarSnipe and DealScout alongside these two, the Marketplace Monitor alternatives and Swoopa alternatives guides go deeper on each, and Australian buyers can compare the alert apps that work in Australia.
