About Marketplace Monitor

Stop Missing Out on the Best Deals! Are you tired of refreshing Facebook Marketplace, Kijiji, and Craigslist every 5 minutes just to find that the best items are already sold? Marketplace Monitor is your secret weapon to scoring the best deals before anyone else even sees them. Whether you are a professional flipper, a bargain hunter, or looking for that one specific piece of furniture, Marketplace Monitor automates the search process for you. Our extension runs in the background, scanning for new listings based on your custom keywords and price range, and alerts you the second a match is found. Key Features Multi-Platform Monitoring: Track new listings across Facebook Marketplace, Kijiji, and Craigslist simultaneously from one dashboard. Instant Notifications: Receive real-time desktop alerts or Telegram notifications the moment a new item is posted. Advanced Filtering: Set specific keywords, price ceilings, and locations to ensure you only get alerts for items you actually want. Background Scanning: Keep the monitor running while you work or browse other tabs. First-to-Message Advantage: Click the notification to jump straight to the listing and be the first to message the seller. How It Works 1. Install the Marketplace Monitor extension. 2. Add Your Searches: Enter your keywords (e.g., "Herman Miller Chair") and set your preferred price and location. 3. Set & Forget: The extension will begin monitoring the platforms in the background. 4. Get Alerted: A notification pops up as soon as a match is found. Click, message, and buy! Privacy & Security We value your privacy. Marketplace Monitor does not store your personal login credentials. It operates as a local tool within your browser to provide the fastest possible updates without compromising your account security. Why Marketplace Monitor? In the world of online second-hand shopping, speed is everything. High-value items on Facebook Marketplace and Kijiji often sell within minutes. With Marketplace Monitor, you stop wasting time manually searching and start winning the "race to the deal."
