Facebook Marketplace alert tools compared: the honest 2026 rundown
Six tools that monitor marketplaces for resellers, with what each one is actually good at. Including where DealSonar is the wrong choice.
SHORT ANSWER
Most of these tools solve the same first problem: telling you a listing appeared. They diverge on what happens next. Swoopa goes deep on vehicles. Marketplace Monitor goes wide on platforms. DealScout is the best free option. DealSonar attaches eBay sold comps and profit estimates to the workflow, for resellers across the UK, US, and EU (list prices in GBP).

Pick by the job you are actually doing
SOURCING CARS
You need VIN, history and a CRM
Swoopa is the specialist. Plate-to-VIN, vehicle history, trade-in and retail pricing, and follow-up tracking. If vehicles are the business, start there.
MANY PLATFORMS
You buy across nine different sites
Marketplace Monitor covers the widest set, including Depop, Shpock, Kijiji and Craigslist. If your sourcing is genuinely spread that thin, breadth wins.
BEING STRAIGHT WITH YOU
When DealSonar is the wrong choice
- You need Craigslist or Nextdoor. DealSonar does not monitor those (it does cover OfferUp alongside Facebook, Vinted and eBay).
- You source vehicles. There is no VIN lookup, no vehicle history and no dealer CRM. Swoopa does that properly and we do not.
- You want a free tool forever. DealSonar has no permanent free tier (7-day trial only). DealScout's free Scout costs nothing and is a reasonable place to start.
- You want a native phone app. DealSonar is a browser dashboard. Alerts reach your phone by email, Discord or Telegram, but there is nothing to install.
FAQ
Why did Facebook Marketplace saved-search notifications stop working?+
Facebook cut back or removed reliable saved-search notifications for many users in 2024 and after. Saving a search may still work, but you often get nothing useful when a new listing matches, which is why third-party monitoring tools exist.
Which tool has the fastest alerts?+
Every vendor advertises an interval, and real-world delivery often lags it. Treat advertised speeds as a ceiling and test on a trial with a category you know well.
Is monitoring Facebook Marketplace allowed?+
These tools are third-party services, not affiliated with or endorsed by Meta. Read each provider's terms, and Facebook's, before you rely on one commercially.
Which is best for UK, US, and EU resellers?+
We are biased, but the honest case is this: Vinted matters in the UK and EU, OfferUp matters in the US, Facebook and eBay are widely used, and profit maths saves the step everyone does manually. That is what DealSonar is built around.
The alert, and the number that tells you to act on it
Facebook Marketplace, Vinted, eBay and OfferUp, monitored 24/7, with eBay sold comps and profit estimates on matching results.
