Your unified deal command center. One app to monitor government auctions and local marketplaces simultaneously.
Deal Detector brings together the world of government surplus auctions and peer-to-peer marketplaces into a single, streamlined desktop application. Instead of juggling multiple browser tabs and manually refreshing auction pages, Deal Detector monitors 12+ sources in the background and delivers matches directly to your Discord inbox the moment they appear.
Built on a clean modular architecture with individual scraper files for each source, Deal Detector is designed for reliability and extensibility. Each scraper operates independently with its own rate limiting, error handling, and parsing logic. The dark-themed Tkinter GUI provides a real-time console with color-coded logging so you always know what the system is doing, while the watchlist engine handles intelligent keyword matching, price-range filtering, and alert deduplication behind the scenes.
Whether you're sourcing inventory for a resale business, outfitting a workshop, or simply hunting for the best price on big-ticket items, Deal Detector collapses hours of manual browsing into a single automated pipeline that works while you sleep.
Track government surplus equipment across 12+ auction sites and local marketplaces simultaneously. Set watchlist keywords like "forklift," "pallet jack," or "commercial oven" with price ceilings and get alerted the instant a matching deal goes live.
Source affordable office furniture, commercial vehicles, IT equipment, and industrial tools from federal and state surplus sales. Save thousands compared to retail by catching liquidation deals before the competition.
