Deal alert tools compared: Swoopa, Outpost Alerts, Marketplace Monitor, Flipify, Copit and Flip Alerts
Every figure for another company is that company's own claim on its own pages, checked October 28, 2026. We make Flip Alerts, so read our row with that in mind; we did not test anyone's speed but our own (our measured numbers are on the start page).

Where each one wins
Outpost Alerts publishes the fastest check for Facebook Marketplace (every minute on its fastest watchlist at $79 a month), has an iPhone app and tracks a deal from found to sold. Pick it if Facebook Marketplace is all you buy on.
Swoopa's own pages now pitch it to used car dealers sourcing private-party cars, with valuations and the widest list of local marketplaces here (Nextdoor, Kijiji, Gumtree). Pick it for cars.
Marketplace Monitor covers UK and European marketplaces (Gumtree, Shpock) next to US ones, with phone apps and an account manager.
Flipify is the cheapest way to one search checked every minute ($10 a month), with phone apps and eBay sold prices next to a find.
Copit is the cheapest fashion-only tool, covers European fashion marketplaces (Vestiaire, The Luxury Closet) and Mercari Japan, with an iPhone app.
Flip Alerts is the only tool in this table that covers all five of Vinted, Depop, Grailed, Poshmark and Mercari together with Craigslist, Facebook Marketplace and OfferUp, so one search can watch a brand across fashion resale and local pickup. It sends to email or Discord with no app to install, has a free plan, publishes its intervals (4 minutes on Pro, 10 on Starter) and shows its measured speed. It is not for you if you need 1-minute checks, phone push alerts or car valuations.
Looking for a Swoopa alternative?
Swoopa lists none of Vinted, Depop, Grailed, Poshmark or Mercari: its higher plans add local marketplaces and eBay. If you flip clothing, shoes and bags, a tool that watches Vinted, Depop, Grailed, Poshmark and Mercari matters more than another local marketplace. If you flip furniture, tools and electronics locally, Craigslist, Facebook Marketplace and OfferUp in one search covers the US basics. Flip Alerts does both from $19 a month, and the free plan shows you real alerts before you pay.
The short version
Flip Alerts in eight facts.
For anyone comparing alert tools.
- What it is
- A service that reads the newest public listings on 8 US marketplaces for your saved searches and sends the new matches, with a link to each listing, to your email or your Discord channel.
- Marketplaces
- Fashion resale: Vinted (US), Depop, Grailed, Poshmark, Mercari. Local pickup: Craigslist (every US area), Facebook Marketplace (24 metro areas, signed out), OfferUp (near your zip). eBay when it lets us read it; Etsy is off because it blocks automated reads.
- How fast
- Each search's pages are read every 4 minutes on Pro, 10 on Starter and 30 on Free. The measured numbers are on the start page.
- Plans
- Free $0 (1 search). Starter $19 a month (5 searches). Pro $39 a month (15 searches). Yearly $190 and $390. 7 days free on paid plans; cancel any time.
- Delivery
- An email digest (at most every 3 minutes on Pro, 10 on Starter, 30 on Free) or each find straight into your Discord channel.
- Logins
- None on the marketplaces. We never sign in anywhere and never get past a bot check: when a marketplace refuses a read, we back off and retry later.
- Filters
- Keywords in the title, words to skip, a price range, Craigslist section and owner-only, miles from your zip.
- Not included
- No phone app, no 1-minute checks, no automatic buying or messaging, no price estimates.

We read public pages only, never sign in to any marketplace and never get past a bot check: when a marketplace shows one or refuses a request, we stop asking it and retry after 15 minutes, then 1 hour, 4 hours and 12 hours. Craigslist, Poshmark and OfferUp are read from cloud servers around the clock; the others from our own browser machine, and they show Paused when it is offline.
