I try to build monitors, not scrapers.

Most tools on this store answer the question "what is listed right now?" and hand you the same thousand rows every time they run. Mine answer a different question: what changed since you last looked? They remember what they have seen, stay quiet when nothing happened, and only produce output when there is actual news. You pay per alert, so a quiet run costs you next to nothing.

That approach comes from how I use these tools myself. Every actor on this profile started as something I built for my own alerts and still run every day. If one of them breaks, chances are I notice before you do.

What you'll find here

Marktplaats Monitor  watches your searches on marktplaats.nl and 2dehands.be and alerts you on new listings and price drops. Much faster than the daily saved search emails.

Kleinanzeigen Monitor  does the same for kleinanzeigen.de, the biggest classifieds site in Germany. Commercial alert services charge serious monthly fees for this. Here you pay per alert.

AutoScout24 Price Monitor  follows your saved car searches in seven European countries and tells you the moment a price gets cut. You configure it by pasting your search URL, so every filter the site supports just works.

European Auction Scraper  pulls live lots from Troostwijk, Vavato, Surplex and other TBAuctions brands into one feed, including an estimate of the real total cost with buyer premium and VAT. Nobody else shows you what a lot actually costs.

All four share the same principles. They read only public data, they pace their requests politely, and they fail loudly instead of pretending a broken site was a quiet day.
