Features & Capabilities

DealMonitor – Track Prices on Any Online Shop

DealMonitor is your personal price tracker for the entire internet. Whether it's Amazon, IKEA, Steam, AliExpress, Etsy, or a small niche shop – DealMonitor automatically detects the price and notifies you when it drops. No shop is too small, no deal escapes you.

🔍 Works Everywhere DealMonitor is not limited to a list of shops. The AI-powered price detection works on any product page on the internet. Visit a page, click the DealMonitor icon, confirm the detected price, and set your target price. Done.

📋 Import Wishlists Import your entire Steam wishlist or Amazon wishlist with one click. DealMonitor automatically scrolls through the list, detects all products with prices, and lets you choose which ones to track. You can set an individual target price per item.

🔔 Notifications on All Channels Get notified when your target price is reached – via email, Telegram, or push notification. You decide per tracker which channels you want to be notified on.

📦 Back-in-Stock Notifications Is a product sold out? Mark it as "Not available," and DealMonitor will notify you as soon as it's back in stock.

📊 Price History Track the price development of your products in clear charts. See at a glance whether a deal is really good or if the price has been lower before.

🛒 Shopping Cart Import Not just wishlists – you can also scan your shopping cart on Conrad, Otto, or other shops and import all items at once.

🌍 31 Languages DealMonitor is available in 31 languages – from German and English to French, Spanish, Italian, Japanese, Korean, Arabic, and Hindi.

🤝 Transparent Affiliate Model DealMonitor uses affiliate partnerships with Amazon, AliExpress, Etsy, and other shops. When you buy through a DealMonitor link, we receive a small commission – at no extra cost to you. Affiliate trackers are free and unlimited. For shops without an affiliate partnership, there's a limit of up to 150 trackers per account.

🔒 Privacy DealMonitor respects your privacy. We don't collect personal data without your consent. All price comparisons are based on public shop data. Your tracker data belongs to you – you can export or delete it at any time.

Is DealMonitor Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

DealMonitor requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Low ******* ****** ** *** ********* ******** ***************
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

DealMonitor is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension has low user count. Unpopular extensions may not be stable or safe.
  • Medium **** ********* *** ******* ** *** **** * ******* *** ******* *** *** ** ****** ** *****
