Facebook's built-in alerts arrive hours late — when they arrive at all. SniprHQ delivers Marketplace listing pushes within seconds of detection, on iPhone, Android, and desktop, with no native app and no Facebook account connection required.
A real-time Marketplace alert has two parts: the detection (somebody has to notice the new listing) and the delivery (the device has to receive the push). Both have to be fast. If detection takes an hour, the alert is useless even if delivery is instant. If delivery is delayed, even instant detection doesn't help.
SniprHQ handles both. Detection is server-side polling at 5–15 minute intervals depending on plan — the polling never stops, regardless of whether your phone is asleep or the SniprHQ tab is open. Delivery is the standard Web Push Protocol that Slack, WhatsApp Web, Twitter, and Discord use for their own pushes. End-to-end latency from listing appearing on Marketplace to push arriving on your phone is typically 2–10 seconds.
The Web Push Protocol delivers through the operating system's notification service rather than a polled connection. That means the push wakes the device the same way a native iMessage or WhatsApp message does. There is no app to keep running, no background sync to wait for, and the alert lands on the lock screen even when the browser is closed entirely.
Web push is supported on every major platform, but the setup steps differ. Here is the actual support matrix as of May 2026:
| Device | Browser | Setup time | Lock-screen push |
|---|---|---|---|
| iPhone (iOS 16.4+) | Safari (add to Home Screen) | ~40 sec | Yes |
| iPad | Safari (add to Home Screen) | ~40 sec | Yes |
| Android | Chrome, Edge, Brave | ~20 sec | Yes |
| macOS | Safari, Chrome, Firefox | ~15 sec | Yes (banner) |
| Windows | Chrome, Edge, Firefox | ~15 sec | Yes (Action Center) |
Apple introduced web push on iOS 16.4 (released March 2023). It works, but only after you add the web app to your home screen via Safari's Share → Add to Home Screen. Open the icon once after installing, enable notifications when prompted, and from then on the iPhone treats SniprHQ pushes the same as native app notifications.
On Android, Chrome surfaces the install prompt automatically the second time you visit. After you tap Install, the app gets a shortcut on the home screen, notifications enable themselves, and you can close Chrome entirely — pushes still arrive.
The push notification itself shows the title, price, location, and image. Tapping it opens the listing directly in Facebook Marketplace — no SniprHQ flow in between, no extra step. The alert also lands in your SniprHQ alert feed for later review.
Each listing is deduplicated against the monitor's history. You get exactly one push per listing per monitor — never repeats. If the same listing is also matched by a second monitor (say a broader and a narrower search both pick up a Stokke Tripp Trapp), you get one push per monitor and can see both in the feed.
This is what the resulting alert feed inside the app looks like — image, title, price, location at a glance:
The most common failure mode for Marketplace monitoring is "I created a monitor for ‘baby chair’ in Sweden, now I'm getting 80 pushes a day, and most of them are junk." The fix is in how you write the monitor:

Facebook's "Save search" button exists, but the resulting alerts are routed through an internal ranking model that decides whether a listing is "worth notifying about." In practice this means 2–4 hour delays for most categories and zero alerts on desktop. Three structural issues make Facebook native alerts unsuitable for resellers:
The full breakdown is on our why FB notifications are delayed page.
Yes. SniprHQ watches Marketplace searches for your saved keywords, price range, and location, then delivers a push notification via the standard Web Push Protocol within 2–10 seconds of finding a match. The push arrives on your lock screen the same way a WhatsApp or Slack message does.
Facebook's saved-search alerts are batched through an internal ranking model and typically arrive 2–4 hours after a listing goes up — if they arrive at all. SniprHQ delivers within seconds of detection, and detection happens every 5–15 minutes depending on your plan.
Yes. The Web Push Protocol delivers via your device’s notification service, not the SniprHQ tab. The push arrives on the lock screen even when the browser is closed and the phone is asleep.
No. SniprHQ is a web app. On iOS you add it to the home screen through Safari’s Share menu (iOS 16.4 or later), open the icon once to enable notifications, and pushes work the same as any native app. On Android, Chrome handles the install automatically.
There is a free tier (1 monitor, 60-minute scans, push enabled). The 48-hour Live Trial gives Pro speed (15-minute scans) with no card required. Paid plans run €29/month (Pro, 3 monitors) and €99/month (Ultra, 5 monitors, 5-minute scans).
Each listing is deduplicated against your monitor’s history. You get exactly one push per listing per monitor — never repeated. If two of your monitors match the same listing, you get one push per monitor.
Title of the listing, price, location, the listing image, and a tap-through link that opens the listing directly on Marketplace. You can decide in seconds whether to message the seller.
Yes. SniprHQ scans Marketplace globally and works wherever Facebook Marketplace is available. The location filter accepts city names, regions, or a radius around a city — anywhere FB Marketplace shows results.
They can — that’s the nature of a broad search. The fix is in monitor setup: narrow the keyword (“Stokke Tripp Trapp” not “baby chair”), set a realistic max price, and add a location radius. A monitor that fires 5–10 times a day with relevant matches is the sweet spot.
The monitor keeps running in the background on SniprHQ’s servers. Alerts continue to fire as listings appear. You can come back to the app any time to see the full alert feed for each monitor.
