How to read the table
The gap is the time between two reads of the same page; for marketplaces that print a posted time, posted to found is how long after posting a new listing was found. Vinted, Mercari, Depop, Grailed and Facebook Marketplace are read in a browser one page at a time with a pause between pages, so when many searches watch one of them, each is read less often; the table shows it when that happens. Depop has no newest-first sort, so a new Depop listing is found only when Depop shows it on the first page of your search.

Starter is $19 a month for 5 searches, read every 10 minutes; Pro is $39 a month for 15 searches, read every 4 minutes; yearly $190 and $390. 7 days free on Starter or Pro, once per account: you enter a card in Stripe's checkout, and if you cancel from your searches page before day 7, nothing is charged. After that the plan renews each month or year until you cancel; a cancel keeps it running to the end of the period you paid for. Write to us within 7 days of a charge for a full refund of that charge.
The only tool here with all five fashion resale sites and local pickup.
From each company's own pages (Outpost Alerts, Swoopa, Marketplace Monitor, Flipify, Copit), checked October 28, 2026. If you only buy on Facebook Marketplace and want 1-minute checks or a phone app, Outpost Alerts publishes those. If you buy on Vinted, Depop, Grailed, Poshmark and Mercari as well as Craigslist, Facebook Marketplace and OfferUp, that mix is what Flip Alerts is for. We make Flip Alerts; we did not test the others' speed. The full comparison, with sources and what we do not do.

How does the free trial work?
Press Start 7 days free on Starter or Pro, type your email, then enter a card in Stripe's checkout. Nothing is charged for 7 days. Cancel from your searches page (Manage billing) before then and you pay nothing. The trial is once per account.
Do I need accounts on the marketplaces?
No. We read public listings signed out. You message and buy on the marketplace as usual.
Can I switch plans or pay yearly?
Yes, from Manage billing on your searches page: Starter to Pro, monthly to yearly, or cancel. Stripe works out the difference.
Which words match?
Every keyword must be in the listing title as a whole word (plurals count). Any word in “skip titles with” removes the listing. A maximum price leaves out listings with no price.
How do I get alerts in Discord?
Server settings, Integrations, Webhooks, New Webhook, copy its address, paste it on your searches page. We post a test message to check it.
Is it running 24/7?
Craigslist, Poshmark and OfferUp, yes, from cloud servers. Vinted, Mercari, Depop, Grailed and Facebook Marketplace are read by our own browser machine; if it goes offline they show Paused on the status table and resume on their own, and the speed table shows any gaps.
Why is a marketplace marked Paused?
It showed a bot check or refused a request, so we backed off. It resumes on its own. A marketplace that keeps blocking reads shows Off until we can read it again; the status table has the current state.
What do you keep about me?
Your email, your saved searches, your Discord webhook address and the alerts we sent you for 14 days. Card details stay with Stripe. See the privacy page.
