Best Facebook Marketplace alert apps (2026): speed, price, and fit compared

Crawlbench is a Facebook Marketplace alert and price-check app. It checks Marketplace for your searches, tells you why each listing passed and how its price compares with similar listings, and sends the alert to the channels you turned on. It is our pick for anyone who runs several searches across several cities, and this guide says where a rival fits better.

Crawlbench is our product and is not affiliated with Meta. Competitor prices and check times below come from each vendor's own pricing page. Six pages were read on 10 October 2026 and four on 17 October 2026 (the dates are in the sources list). These are the same ten rivals as on best Facebook Marketplace monitoring tools, which shows the oldest date, 10 October 2026, for the set. Check each vendor's page again before you pay.

What is the best Facebook Marketplace alert app in 2026?

For buyers who run several searches across several cities, Crawlbench is our pick. Cheaper and narrower apps fit other cases:

• Several searches, several cities, a reason on every alert: Crawlbench. Each plan checks busy cities at its own speed, and every search on the plan gets that speed.
• One search on the smallest bill: Flipify, at $5 a month for a watchlist checked every 10 minutes (read 17 October 2026).
• Craigslist, OfferUp or eBay in the same app: Classifindr, Botifex or Swoopa.
• Cars only, with a browser open all day: CarSnipe.
• Casual buying: Facebook's own saved searches. It publishes no schedule for them.

How often does each app check?

Crawlbench checks busy cities every 10 minutes on Starter, every 5 on Growth, every 2 on Pro and every minute on Scale, as pricing shows on 18 October 2026. A rival's speed below is the speed its own page states for the plan named.

Sources and read dates are in the list at the end. Facebook's saved searches are free and publish no schedule.

Each app in detail

Crawlbench: several searches and cities, with a reason on every alert

Crawlbench is a hosted alert and price-check app for Facebook Marketplace, built for flippers, dealers and sourcing teams. A search is a category, its filters, a keyword list and the cities it covers. Vehicle searches send make, model, year, mileage, transmission and body style to Facebook on each check, and excluded terms remove junk before it reaches you.

• Several cities in one search: pick cities or go nationwide.
• Every alert explained: each listing shows the reasons it passed your filters and how its asking price compares with similar listings.
• Every category: vehicles, real estate, electronics, cameras and your own custom category, with keyword lists, make and model, price, year, mileage and excluded terms.
• Alerts where you work: Telegram, email, Slack and Discord, plus a list of listings that pass, which you can open from any device.
• Saved: save a listing and Crawlbench re-checks it and tells you when the seller cuts the price.
• No Facebook login, nothing to keep open: Crawlbench runs in the cloud and never asks for your Facebook password. You message sellers yourself.
• Price: a free Day Pass for one search for 24 hours, no card. Then Starter $39 a month (3 searches), Growth $79 (8) and Pro $199 (20), with Scale on request. Paid plans start with 3 days free. See pricing for what each plan includes.

• Price: Basic $14.99 a month, up to Pro at $79. 3-day trial, no free plan (read 17 October 2026).
• Speed: the page gives every 30 minutes on Basic, every 3 minutes on Standard and every minute on Pro, for the fastest watchlist on each plan. Other watchlists on Standard and Pro run slower.
• The catch: the one-minute check covers one watchlist, and only on the $79 plan.

Facebook saved searches: free, no schedule

Facebook can notify you about a saved Marketplace search for free, but it publishes no schedule, and buyers report alerts that arrive late or not at all. See why Facebook Marketplace alerts stop working and how saved search notifications behave.

What five searches cost on each app

Five searches is a common starting point: a few models, or one item in a few cities. The question is how many of those five run at the speed you are paying for:

• Crawlbench: all five run at the plan's speed. Growth at $79 covers 8 searches, checked every 5 minutes in busy cities.
• Outpost Alerts: its Standard plan gives one watchlist a 3-minute check, and the page says the others run slower.
• Flipify: $50 a month for five one-minute watchlists.
• Marketplace Monitor: its page prices five searches by find time. See its pricing page for today's figure.

How to test alert speed during a trial

The best test is to run Crawlbench next to the app you use today:

1. Pick one search that gets several new listings a day in your area, such as a popular phone model or a common pickup truck.
2. Set up the same search, with the same price cap and radius, on Crawlbench and on your current app.
3. For each alert, open the listing and note how long ago Facebook says it was posted.
4. After 20 alerts, compare the typical gap and count the alerts you would never act on: wrong model, parts only, wanted ads.
5. Keep the app that gets you to more listings you would act on, sooner.

The Day Pass covers the first day of this test, and the 3 free days on a paid plan cover the rest. To cut junk after the first alerts, see tighten Marketplace filters after junk alerts.

Which app should you pick?

Pick Crawlbench if Facebook Marketplace is where you buy and you run several searches across cities. The others make sense in narrower cases:

• A single search on the smallest budget: Flipify.
• Craigslist, OfferUp or eBay in the same app: Classifindr, Botifex or Swoopa.
• Cars only, with a browser open all day: CarSnipe.

Whatever you pick, never let an app message sellers for you from your Facebook account. Read what is safe in a Facebook Marketplace bot before you connect anything to your profile.

Frequently asked questions

What is the best Facebook Marketplace alert app?

Crawlbench is our pick for buyers who run several searches across several cities, with a reason and a price comparison on every alert. Flipify is the smaller bill for one search, and CarSnipe fits cars only. Try Crawlbench free for a day with no card.

Is there a free Facebook Marketplace alert app?

Yes. Crawlbench has a free Day Pass: one search for 24 hours, no card. Facebook's saved searches are free but follow no published schedule, and DealHunter's free plan checks once a day.

Is there a Facebook Marketplace alert bot?

Yes. Crawlbench sends alerts to a Telegram bot, and also to Discord, Slack and email. These bots only send listings to you; they never message sellers for you. Setup guides: Telegram alerts and Slack alerts.

How fast can Facebook Marketplace alerts be?

It depends on the plan. Crawlbench checks busy cities every 10 minutes on Starter, 5 on Growth, 2 on Pro and every minute on Scale, as pricing shows on 18 October 2026. Outpost Alerts states a one-minute check for one watchlist on its $79 plan. Facebook publishes no timing for its own saved-search alerts.

Do Facebook Marketplace alert apps need my Facebook login?

Crawlbench never asks for your Facebook login. It runs in the cloud, so there is nothing to keep open on your computer. CarSnipe runs inside your own browser with your Facebook session.

Does Facebook have an official Marketplace alert API?

No. Facebook does not offer a public Marketplace API for deal alerts, so every app on this list checks Marketplace itself and sends you what it finds.

Can I use more than one alert app?

Yes. Run Crawlbench next to your current app for a week, log the listing age at each alert and the junk rate, and keep the one that wins. For the wider field, see best Facebook Marketplace monitoring tools.
