Free Price Tracker — Why DealMonitor?
AI-Powered Price Detection
Our machine learning model learns from every price confirmation to detect prices accurately on any website. No manual setup required—just paste a URL and let the AI find the right price automatically.
Your Data is Safe
All data is stored on servers in Germany. A blacklist prevents tracking on sensitive sites like banks. Passwords are hashed with bcrypt, and all connections use TLS encryption.
Free
DealMonitor is completely free to use with no subscription and no hidden costs. The service is funded through affiliate links, which never affect the prices you pay.
Works Everywhere
Track prices on virtually any online shop—Amazon, eBay, IKEA, Steam, and thousands more. Use our browser extension for one-click tracking or paste any product URL directly into the web app.
Price History
View detailed price history charts for every tracked product. Filter by time range, see price statistics, export data as CSV, and share price histories with friends via public links.
Daily Improvements
DealMonitor gets smarter every day. Our ML model and shop compatibility list are updated continuously based on user feedback through automated CI/CD pipelines.
