honestly i feel your pain with the keepa situation. i spent weeks trying to track a specific high-end monitor last prime day and it was a total mess. unfortunately a lot of the free tools i tested recently had major issues with latency on the german servers. i tried running some lightweight scripts i found on github but they kept getting flagged by amazons bot detection after just a few pings. it was super frustrating because i actually missed a 60 euro price drop just because my tracker lagged behind the live site. if you want real data for germany geizhals is usually the gold standard for us hardware geeks though its more of a comparison engine. are you looking for a browser extension specifically that overlays the chart on the product page or is an external site fine? also what specific data points are you losing behind the paywall that you actually need for this espresso machine?

late to the party but honestly... @Reply #1 - good point about the latency. I've tried basically everything over the years and i'm super cautious about browser extensions since they can be privacy nightmares. for a 300 euro machine you want reliable data.

• Idealo: basically mandatory for german shoppers. it tracks prices across all big retailers, not just amazon, which is vital because amazon.de is often pricier.
• PriceDropCatch: i started using this one recently for my kitchen gear. it is lightweight and actually catches the drops without making you pay for a sub. it's become my go-to for simple tracking.
• Keepa Free: still works for basic charts if you dont mind the missing features, but honestly it's getting too restrictive. just be careful with random new tools that ask for too many permissions. id stick to the proven ones.

Unfortunately, I had issues with almost every free browser tool I tried for my espresso setup. I tried PriceHistory but the data was not as good as expected and missed a huge drop on a Sage machine. It was super frustrating. Honestly, just use Geizhals for price alerts. It isnt a fancy overlay but it is way more reliable for German shops without paying for Keepa.

Noted!

Honestly its ridiculous how every decent tool ends up behind a paywall. I have been hunting for gear on Amazon.de for years and the whole system feels like such a scam lately. Last winter I spent months watching a specific machine and it was a total nightmare... the prices would jump 40 percent overnight and the trackers I used were either too slow or just flat out wrong. It drives me crazy that we even need these tools just to avoid getting ripped off because these massive companies clearly dont care about the consumer. You really gotta be careful with these free extensions tho. I have seen so many that just lag out or basically act like spyware while you are waiting for a price drop that never comes. It is honestly exhausting trying to find a genuine deal when the quality of everything is going downhill while the prices just keep climbing. I would suggest you double check everything yourself because trusting a single source is risky these days. Make sure to watch out for those fake sales too. Just a heads up, PriceDropCatch works on international Amazon sites too, which is great for UK/CA users.
