We are thrilled to announce that DealMonitor has officially entered beta! What started as a simple idea, tracking prices across any online store, has grown into a full-featured price monitoring platform. Today we are celebrating this milestone by looking back at everything we have built to get here.
From Alpha to Beta: The Journey
When DealMonitor launched in alpha, it could do one thing: detect prices on web pages using machine learning and notify you by email when they dropped. That core idea has not changed, but everything around it has been transformed. Over the past months, we shipped dozens of features, squashed hundreds of bugs, and listened closely to your feedback. The result is a tool we are genuinely proud of.
Let us walk through the highlights.
Notifications Your Way
Email alerts were just the beginning. DealMonitor now supports three notification channels so you never miss a deal:
- Email — The classic. Get a beautifully formatted email the moment your target price is reached.
- Telegram — Connect your Telegram account in seconds and receive instant price alerts right in your chat. Perfect for deal hunters who live on Telegram.
- Web Push — Enable browser push notifications and get alerts even when DealMonitor is not open. Works on desktop and mobile.
You can mix and match per tracker, so your high-priority items get Telegram pings while everything else stays in email. Each tracker has independent notification toggles.
Dark Mode
We heard you. The dashboard, landing page, and every corner of DealMonitor now support dark mode. Choose between light, dark, or system-automatic themes. Your preference is remembered across sessions. No more blinding white screens at midnight while checking your deals.
Cross-Shop Price Comparison
When we detect the same product across multiple shops (via GTIN matching), your tracker card now shows a "Also available at" section with prices from other retailers. Find the best deal without leaving your dashboard.
AI-Powered Price Detection, Now Even Smarter
Our machine learning model has been upgraded to v4 with a new CatBoost classifier. It is faster, more accurate, and handles edge cases that tripped up earlier versions. The detector service now supports hot-swapping models, so we can roll out improvements without any downtime.
Every tracker you create helps the model learn. Thank you for making it better with each confirmed price.
Amazon PA-API Integration
Amazon products now use the Product Advertising API for reliable price fetching, no Selenium needed. This means faster updates, accurate pricing, and automatic ASIN extraction. If the API is unavailable, DealMonitor gracefully falls back to standard scraping. It just works.
Dashboard Overhaul
The dashboard has been rebuilt from the ground up:
- Tracker groups — Organize your trackers into custom groups with drag-and-drop reordering.
- Search and filter — Instantly find trackers by product name, shop, or URL.
- Price history charts — Beautiful step charts with time range filters (1W, 1M, 3M, 6M, 1Y, All) and price statistics.
- CSV export — Download your complete price history for any tracker.
- Share links — Share a product's price history with anyone via a public link.
- Check priority — Set high-priority trackers to be checked every hour instead of every 4 hours.
- Report broken tracker — See a tracker that is not working? One click sends a report to our team so we can investigate.
Performance and Reliability
Behind the scenes, we have been obsessing over speed and stability:
- Parallel scraping with per-shop cooldowns ensures we check prices efficiently without overwhelming any single store.
- Database indexes on all key columns make dashboard loading instant, even with hundreds of trackers.
- Health checks on all containers ensure automatic recovery from failures.
- Sentry integration catches errors before you even notice them.
- Automated backups with NAS sync keep your data safe.
Privacy and Security
Your data is yours. DealMonitor stores everything on servers in Germany, passwords are hashed with bcrypt, and all connections use TLS. We rewrote our privacy policy from scratch with 13 detailed GDPR-compliant sections so you know exactly what happens with your data.
The browser extension only activates on whitelisted shop domains and never monitors your general browsing. A shop blacklist prevents tracking on sensitive sites like banking portals.
SEO and Sharing
Share pages now include rich Open Graph and Twitter Card metadata, so when you share a deal link it shows a beautiful preview with the product image, price, and shop name. We also added structured data (JSON-LD), a sitemap, and robots.txt for better search engine visibility.
Nine Languages
DealMonitor speaks your language. The entire app, including emails, is available in English, German, Spanish, French, Italian, Hindi, Chinese, Arabic, and Russian. Language detection is automatic based on your browser preferences.
What is Next
Beta is not the finish line, it is the starting line for the next phase. Here is what we are working on:
- Advanced analytics dashboards with spending insights
- Browser extension improvements and cross-browser support
- Deal sharing and social features
- Even smarter price detection with variant tracking
- Mobile app exploration
Thank You
None of this would be possible without our early users. Every tracker you created, every price you confirmed, every bug you reported made DealMonitor better. We are building this for you, and your feedback continues to shape the product every single day.
