Best Facebook Marketplace alert apps
An alert app checks Facebook Marketplace for new listings and tells you when one fits your search. There is no official Facebook Marketplace feed for this, so every app does the checking itself. None of them should message sellers for you. The apps below are compared on what their public pricing pages say, on 18 Oct 2026, and each fact names its page. Crawlbench publishes this guide and sells the first app on it.
Free Day Pass, no card · a price check and a review of every listing
Prices and check speeds checked on 18 Oct 2026, from each app's public pricing page.

Crawlbench for Facebook Marketplace
A web app for Facebook Marketplace in every category. Each new listing is priced against similar listings and reviewed with reasons, and a team desk on Pro and Scale keeps two people from messaging the same seller.
Best when Facebook Marketplace is where you buy and you want to know if the price is good before you message.
Busy cities are checked every 10, 5, 2 or 1 minutes, depending on your plan. Alerts via Email, Telegram, Slack, Discord and the Phone app. Free Day Pass for 24 hours, no card.
What to compare
Crawlbench publishes these guides and sells a competing product. These criteria are the ones we use, so read the other pages the same way. Use them on any vendor page.
-
Where you buy
If Facebook Marketplace is your source, an app built for it beats marketplaces you never open.
-
What you pay a month
Entry plans of the apps checked on 18 Oct 2026 range from $5 to $47 a month. The cheapest plan is not the cheapest purchase if it misses the listing.
-
How often it checks
Each page states its own speed. Compare the plan you would pay for, not the fastest plan on the site.
-
What it tells you about a listing
A price against similar listings and a reason to look or skip save the most time once you have more than a few searches.
-
The alert you will open
Telegram, email, Slack, Discord or a phone app only help if that is where you already are when you source.
-
What it does not do
No tool here sends a message to a seller for you. You message from your own Facebook account.
Start with Crawlbench unless one of these fits you better
If you buy on Facebook Marketplace, start with Crawlbench. Open a card only if a narrow constraint pushes you elsewhere.
Facebook Marketplace buyer Most of your purchases already come from Facebook Marketplace
Default pick Crawlbench

Pick this one if CarSnipe

Skip if You add rentals, electronics or furniture, or want each listing priced and reviewed
Several marketplaces You buy on several marketplaces, not Facebook Marketplace alone
Pick this one if A multi-marketplace app
Breadth pays when other marketplaces still produce purchases you can name. It is wasted when Facebook Marketplace is your only source.
Skip if Facebook Marketplace is where you buy and the other marketplaces sit unused
Sold price first You will not drive until a sold price looks right
Pick this one if SuperFlip AI
Sold prices from resale sites matter when one bad drive costs more than a late alert.

For people who buy on Facebook Marketplace and want each listing priced and reviewed, Crawlbench. For the lowest price on vehicle alerts, CarSnipe. For several marketplaces in one app, Swoopa or Botifex.
Is there a free option?
Facebook's own saved searches are free. Crawlbench has a free Day Pass for 24 hours with no card. DealHunter, SuperFlip AI and Botifex each have a free plan, with the limits on their pricing pages.

Entry plans of the 10 apps checked on 18 Oct 2026 run from $5 to $47 a month. Crawlbench plans are $39, $79 and $199 a month, and Scale: ask us.
Do these apps message sellers for me?
No. Each one shows you listings, and you message from your own Facebook account.

Should I try two?
