E-commerce sellers lose orders every day to competitors who quietly drop prices. By the time you notice, they have reviews and rankings you cannot catch up with overnight.
PriceSentinel Pro runs in the background and alerts you the moment a competitor price changes.
Features
- Scheduled scraping of competitor product pages
- Compare against historical price data
- Alert via email, DingTalk webhook, or WxPusher
- Weekly price trend reports
- Amazon ASIN support + custom CSS selectors
Typical Setup
- Add target URLs to config.json
- Set check frequency (recommend every 30+ min)
- Configure your alert method
- Schedule with cron or Windows Task Scheduler
After one week: you have a full price history chart and can see your competitor's promotion patterns.
Runs 100% locally. All data stays on your machine.
