The lowest price
$29.99/mo (or $239.99/yr) — the most affordable way to run JDMarket, because your own computer does the searching.
10 watches, instant alerts
Run up to ten active watches and get instant alerts on every one — the moment a listing goes live. No fast-watch limits.
Message sellers first
When a listing scores 5/5 against your filter, the agent can send your opening message automatically — before the crowd even sees it.
Your session stays local
The agent uses your own Facebook session on your own machine. Nothing about your login is sent to us.
Windows, macOS & Linux
One lightweight app, all three desktop platforms. It runs in the background while you do everything else.
Paste any search URL

Desktop questions, answered.
Which systems does the desktop app support?+
Windows, macOS and Linux. It's a small native app that installs in seconds and runs quietly in your tray or menu bar.
Does my computer have to stay on?+
Yes — the agent searches from your own machine, so it watches Marketplace whenever your computer is awake and connected. If you'd rather not leave a computer running, the app plans (from $30/mo) do the searching for you 24/7 instead.
How is this different from the app plans?+
Desktop runs on your computer with your own Facebook session — it's cheaper, supports 10 watches with instant alerts the moment a listing goes live, and can auto-message sellers first. The app plans (Basic/Pro/Premium) run in the cloud with nothing to install and no Facebook login, but can't message sellers. They're separate plans — see the comparison below. One more difference: Desktop watches Facebook Marketplace only, while the app plans can also watch Craigslist & OfferUp (US), Kijiji (Canada), and Gumtree (UK).
Can it really message sellers for me?+
Yes. On a 5/5 AI match you can have the agent send your opening message to the seller automatically, the moment the listing appears — this is only possible on Desktop because it uses your own Facebook session.
Is there a free trial?+
Yes — a 3-day free trial. You add your card through Stripe checkout, pay nothing for 3 days, and it converts to $29.99/mo automatically on day 3 unless you cancel first.
