I kept losing rare items on eBay while asleep in Tokyo. By the time I woke up, the listing was gone. So I built FindAlert. Set a keyword, pick your marketplaces and countries, get an email the moment something matches. No AI scoring, no recommendations — just raw data. Price, watcher count, seller rating. You decide. What it covers: eBay (16 countries), Reverb, Discogs, Gumtree, Marktplaats. 19 marketplaces total. Free tier available. Paid plans from $19.99/mo.
