WHAT IS IT?
PriceGhost is a self-hosted price tracking application. You add a product via its URL, the app automatically extracts the price and monitors it at regular intervals. When the price drops, you get a notification. That's it.
WHY IS IT INTERESTING?
- Multi-strategy extraction: JSON-LD, site-specific scrapers, generic CSS selectors, and AI-powered analysis as fallback (Claude, GPT, Ollama). If one method fails, the next one kicks in.
- Human validation: a "voting" system lets users confirm or correct the extracted price. The app learns from your corrections.
- Multi-channel notifications: Telegram, Discord, Pushover, ntfy.sh, Gotify. Pick where you want to be alerted.
- Site-specific optimizations: Amazon, Best Buy, Walmart, Target, Costco, eBay, Newegg, Home Depot, AliExpress and Magento 2 stores are natively supported with dedicated scrapers.
- Full PWA: dark/light mode, multi-user support with admin panel, and one-command Docker deployment.
USE CASES

- Track PC component or appliance prices over time with the built-in history charts
- Get notified when an out-of-stock product comes back
- Centralize price tracking for a whole family or team with multi-user support
