Everything runs locally on your machine.

What v2 adds

• New shared multi-platform watchlist for Facebook, Wallapop, and Vinted
• Dedicated tabs for Facebook, Wallapop, and Vinted
• Shared settings for Discord webhooks, bot toggles, poll intervals, and Vinted cookie input
• Worldwide Vinted support — pick your country (US, UK, FR, DE, IT, NL, PL, PT, etc.) and the bot hits the right domain
• Location is now user-configurable — no more Spain-only defaults; set your own city + coordinates in Settings
• Discord alerts routed to All, Buy Now, and Maybe webhooks
• Discord alerts are optional; the app still runs normally without any webhook configured

Supported bots

Bot	Purpose
Cars	Original Facebook Marketplace car scanner
Facebook	Electronics sniper driven by the shared watchlist

Download & install

Grab the latest release from the Releases page:

Platform	File
macOS (Apple Silicon)	FBM.Sniper.Community-2.0.4-arm64.dmg

macOS "app is damaged" warning

The app is unsigned, so Gatekeeper may block it the first time. If that happens, run:

xattr -cr "/Applications/FBM Sniper Community.app"

Then open it again.

Windows SmartScreen warning

The Windows build is unsigned, so SmartScreen may show a warning. Click More info and then Run anyway.

First launch

1. Open the app.
2. Review your location in the Settings tab. Dallas, TX is only the starter location; change it to your real search city, or save it to confirm Dallas. The banner stays up until this is done.
3. If you plan to use the Vinted bot, pick your country from the Vinted Country dropdown in Settings (or in the Vinted tab's inline settings strip).
4. Log into Facebook in the browser window if you plan to use the Cars or Facebook bot.
5. Review the shared watchlist, bot toggles, and polling intervals.
6. Add Discord webhook URLs only if you want alerts. They are optional.
7. Start the bot you want from its tab.

Discord webhooks

Discord notifications are controlled from the Settings tab:

• All Webhook: every graded deal
• Buy Now Webhook: grades A and B
• Maybe Webhook: grades C and D

Leaving all three blank disables Discord delivery without affecting the snipers.

Vinted country + cookie setup

Vinted runs a separate site per country (www.vinted.es, .fr, .de, .co.uk, .com, etc.). The Vinted bot won't start until you pick your country from the dropdown in Settings → Vinted. Supported countries: United States, Spain, France, Germany, United Kingdom, Italy, Netherlands, Belgium, Poland, Czechia, Slovakia, Austria, Portugal, Luxembourg, Lithuania, Finland, Sweden, Denmark, Hungary, Croatia, Greece, Romania, Ireland.

A manual cookie is optional — the bot auto-fetches one from whatever country you pick. If you want to supply your own (stronger bypass), the value must include access_token_web=... from the same Vinted country domain you selected.

Quick way to get it:

1. Log in to your country's Vinted site (e.g. www.vinted.fr).
2. Open your browser devtools.
3. Find the request cookies for that domain, or inspect the site cookies under Application/Storage.
4. Copy the cookie string that contains access_token_web=....
5. Paste it into the Vinted cookie field in Settings, or export it as VINTED_COOKIE.

If you do nothing, the bot still attempts automatic cookie refresh on its own.
