Windows 10/11	`FBM Sniper Community Setup 2.4.1.exe`
Linux x86_64	`FBM Sniper Community-2.4.1.AppImage`

Install and run

Follow the installation steps below for your platform. No sign-in screen will appear; the app opens straight to the dashboard.

Installation

Mac users also need: Mac Install Helper (Mac users run me first).sh from the same Discord download post.

Save both files to Downloads

Both the .dmg and the install helper script.

Open Terminal and run the helper

bash ~/Downloads/Mac\ Install\ Helper*.sh

Enter your Mac password when prompted.

One-time approval (if needed)

If macOS shows "FBM Sniper Community was blocked from use": System Settings, Privacy & Security, scroll down, click Open Anyway. One-time only.

App opens straight to the dashboard

No sign-in screen. You're in.

Run the installer

Double-click FBM Sniper Community Setup 2.4.1.exe.

Bypass the Defender warning

Click More info, then Run anyway. Expected on unsigned builds.

Launch from the Start Menu

The app opens straight to the dashboard. No account needed.

Save the AppImage and make it executable

chmod +x ~/Applications/FBM\ Sniper\ Community-2.4.1.AppImage

Double-click or launch from terminal

No install step required. The AppImage is fully self-contained.

⚠

Ubuntu 24.04+ sandbox error? Run with --no-sandbox appended.

First launch: Chrome download

All platforms download Chrome (~150 MB) into your user-data folder on first launch. The app shows "Setting up sniper engine..." for 30 to 90 seconds. One-time only; subsequent launches are instant.

Configuration

Complete these steps before starting your first scan. The bots refuse to start until location is set, and an amber banner will stay pinned to the top of the dashboard until you do.

1

Set your location Required

Settings, Connection & Region, paste lat/long coordinates. Get them from Google Maps: right-click any spot, click the coordinates to copy. Decimal format only, e.g. 40.4168, -3.7038. Do not type a city name.

2

Set your Facebook Marketplace URL Required for FB

Open facebook.com/marketplace, set your city via the location pin, copy the full URL from the address bar, paste into Settings. Leave blank if you don't use Facebook.

3

Pick your display currency

Settings, Display Currency. Every price in the app converts from its native currency into your chosen one at runtime. No restart required.

4

Add proxies Strongly recommended

Facebook will block your home IP within minutes without a proxy. Format: http://user:pass@host:port, one per line in the Proxy Pool field.

5

Set your Gemini API key Required for AI

Free key at aistudio.google.com/apikey. Settings, AI Review, paste it in, set AI Workers to 3. Without it the app falls back to basic programmatic scoring.

6

Set up Discord notifications Recommended

Server Settings, Integrations, Webhooks, New Webhook. Paste the URL into Settings, Notifications. Most users only set the Buy Now webhook (grades A and B).

7

Pick your Vinted country Required for Vinted

Settings, Platforms, Vinted Country. No cookie needed; the bot mints one automatically on first scan.

8

Configure eBay sold-comps Recommended

Settings, eBay. Set your regional marketplace (EBAY_US, EBAY_GB, etc.) and resale economics so the grader can compute real profit estimates.

Proxies in detail

The recommended provider is Oxylabs Residential Proxies (affiliate link). Any rotating residential proxy works. Add them one per line:

http://username:password@proxy.host.com:port

Gemini API key

The free Gemini tier is plenty for personal use. Get your key at aistudio.google.com/apikey, paste it into Settings, AI Review, and set AI Workers to 3 to start.

Discord notifications

Three routing slots in Settings, Notifications:

All Deals: every graded deal regardless of grade
Buy Now: grades A and B only
Maybe: grades C and D

Vinted & eBay

Vinted country is required before the bot will start. Settings, Platforms, Vinted Country. Cookie capture is automatic.

eBay sold-comps give the AI real resale prices. Settings, eBay: pick your regional marketplace and set your fee %, ship reserve, and target profit %.

Your Watchlist

The watchlist is the list of products you want the bots to find. The Community Edition ships with 38 pre-configured targets ready to go.

Pre-loaded targets

iPhones: 12, 13, 14, 15, 16, 17 (all variants: mini, Plus, Pro, Pro Max, e, Air)
Samsung Galaxy: S23/S24/S25 Ultra, S24/S25 base
Google Pixel: 9 Pro, 9, 8 Pro
PlayStation 5: Pro, Slim Disc, Slim Digital, Disc, Digital

Each target has sensible price floors and ceilings, accessory blocking ("cord only", "case only", "for parts"), and AI Instructions tuned for the typical scam patterns on that product.

Toggle any target on/off from the Watchlist tab. Group headers have an "all on / all off" pill to flip the whole group at once.

Adding targets

Fast way: AI generator

Watchlist, Generate with AI. Type a one-line description: "unlocked iPhone 15 Pro under $700, no cracked screens, 256GB or more".

Click Generate. The AI fills the full schema: query, must-include keywords, must-avoid keywords, price ceiling, AI Instructions.

Review, paste your eBay sold-listings URL (the AI leaves this blank), then Save.

Manual way

Watchlist, Add Target. Key fields:

Field	What it does
Search Query	Keep it tight: `iPhone 15 Pro`, not `apple phone 15`.
Min / Max Price	Hard ceilings. Anything outside is silently skipped.
Must Include	At least one of these must appear in the listing text.
Must Avoid	Listings with any of these are hard-rejected before grading.
AI Instructions	What you tell Gemini to look for and reject for this product.
eBay Sold-Comps URL	A saved eBay sold-listings search. Used for resale-value lookup.

Writing good AI Instructions

Tight prompts mean the A-grade bucket is actually A-grade. The shape that works:

Score [PRODUCT] listings tightly. A "good deal" means: [positive criteria].
Hard reject anything that says [scam patterns / red flags].
Be skeptical of prices >X% below recent eBay sold comps.
If [unclear detail], score one tier lower.

What works well: specific scam patterns for that category, storage/config sensitivity, resale anchoring ("be skeptical if more than 40% below sold comps"), and photo cues ("if photos show only the box, reject").

Built-in iPhone example:

Score iPhone listings tightly. A "good deal" means: visibly clean device (no spider cracks), unlocked or factory-unlocked (NOT carrier-locked, NOT iCloud-locked), genuine Apple (not a "1:1 clone"), with at least the original cable shown, and battery health 80%+ if disclosed. Hard reject: "for parts," "demo unit," "bad IMEI / blacklisted," "MDM locked," or photos showing only the box or charger. Be skeptical of prices >40% below recent eBay sold comps. If storage is unclear, score one tier lower.

Running your first scan

Confirm Settings is fully saved. No amber banner at the top means you're good to go.

Open the Wallapop or Vinted tab first. They're the most forgiving and prove your watchlist + AI grading work end to end.

Click Start. Watch the log panel:

[wallapop] scan cycle 1 starting... [wallapop] fetched 23 listings, 23 new [wallapop] grading 23 listings via Gemini (3 workers)... [wallapop] grade results: 1×A, 3×B, 5×C, 8×D, 6×F

Open Found Listings and filter by grade A/B to see the buy-now candidates. Once your proxy is confirmed working, add Facebook next.

⚠

Don't start all nine bots simultaneously on day one. Start with two or three and tune from there.

Found Listings tab

The unified deal feed. Every graded listing from every marketplace appears here.

Card layout

Each card shows: source platform badge, primary photo (use ‹ and › to carousel through more), title, price in your display currency, target name, grade, and AI verdict notes.

Grade meanings

Grade	Meaning	Action
A	Strong deal, far below max-buy	Race to it
B	Good deal	Worth a message
C	Fair deal	Worth checking
D	Lowball target	Low-offer only
F	Skip / junk / scam	Ignore
?	No reference price	Review manually

Filters

Search by title: quick keyword filter
Filter by platform: focus on one marketplace at a time
Filter by grade: A+B (Buy Now), C+D (Maybe), or everything
Platform chips: toggle entire platforms on/off from the feed

Actions per card

Open: opens the listing in your browser
Not Relevant (x): hides this listing permanently

💬

Want one-click messaging and hands-free Auto-Message?

Pro adds Linked Accounts (Facebook + Vinted) so you can message sellers directly from the card, plus Auto-Message that fires automatically when a listing matches your target.

Per-marketplace notes

Marketplace	Notes
Facebook Marketplace	Needs proxy. Needs Facebook Marketplace URL in Settings. Rate-limits aggressively without one.
Wallapop	Mostly rate-limit tolerant. Best place to start. Raise the poll interval if you see 429 errors.
Vinted	Country selection required. Cookie capture is automatic. Use rotating proxies in the chosen country for Datadome bypassing.
Mercari	US and Japan supported. Open button goes straight to the listing page.
Leboncoin	France only. Headed Chromium needed for some listing categories.
Kleinanzeigen	Germany / Austria. Watch for region-specific currency display.
Gumtree	UK, Australia, South Africa share one bot. Defaults to UK; override per-target.
Yaga	Estonia, Latvia, Lithuania. Smallest catalog; fastest to validate new targets against.
OfferUp	US only. Built on OfferUp's real GraphQL schema, pages naturally without scraping.

Settings

Tab	What's there
Connection & Region	Proxy, currency, location lat/long, Facebook Marketplace URL
AI Review	Gemini API key, concurrent workers, AI on/off toggle
eBay	Marketplace, currency, profit thresholds, fees, cache refresh
Notifications	Discord webhooks (All / Buy Now / Maybe), browser auto-open
Platforms	Per-platform on/off, polling intervals, Vinted country
Advanced	Search/detail concurrency, raw config JSON view

Daily workflow

Open the app and glance at your Discord Buy Now channel for overnight A/B hits.

Click Start on the bots you care about.

Triage Found Listings as new ones come in. Open promising ones in your browser, hit x on the clearly irrelevant ones.

Click Stop at the end of the day.

✓

Once a week, look at grade-F listings in Logs. If you spot a real deal in there, tighten the mustAvoid keywords or adjust the AI Instructions for that target.

!App is hung at startup ("Setting up sniper engine..." forever)▾

This is the first-launch Chrome download (~150 MB), which takes 30 to 90 seconds. If stuck after 3 minutes, check that the app isn't blocked by your firewall. Restart the app.

!Scan returns zero results▾

Location not set: Settings, Connection & Region, fill in lat/long
No proxy on Facebook: FB blocks your IP within minutes. Add one.
Vinted country wrong: Settings, Platforms, Vinted Country
All targets disabled: Watchlist, check the toggles
Price band too tight: your max price may be below market

!AI grading isn't running▾

Settings, AI Review: confirm Gemini API key is set and saved
Settings, AI Review: confirm "Use AI grading" toggle is on

Watchlist Presets	Save and swap named watchlist snapshots. "iPhones Only" vs "Phones + Cameras" with one click.
Seller trust filters	Set minimum review count and minimum star rating. Listings from sketchy accounts get filtered out before grading.
