eBay Homelab Deal Hunter
An autonomous market scanner that continuously tracks thousands of eBay enterprise hardware listings (Lenovo Tiny, Dell Micro, HP EliteDesk, ECC RAM, Coral TPUs, and NVMe drives). Using regex spec extractors and dynamic P20 percentile pricing models, Deal Hunter filters through messy listing titles to alert on genuine below-market homelab bargains.

Active eBay auctions and Buy-It-Now items tracked across 12 rule sets.

Filter Live eBay Hardware Deals
Search active deals retrieved from the homelab SQLite database via read-only parameter queries. Filter by hardware family, configuration tier, RAM capacity, or maximum budget.
Automated Market Price Curves
How Deal Hunter detects real bargains: by computing rolling sample counts, median clearing prices, and 20th percentile targets (P20) across specific hardware configurations.
Read-Only Architectural Isolation (?mode=ro)
The internal eBay scanner daemon runs isolated in the background on Proxmox CT 104,
updating deal_hunter.db via WAL mode. When the website API queries listings,
it opens SQLite using the read-only URI flag (file:...deal_hunter.db?mode=ro)
paired with strictly parameterized queries. The scanner's mutation endpoints (port 8004)
are never exposed to the public Internet.
