If you remember Treasury, I've collected all the domains listed on ProductHunt. Released the first version on October. There were 1045 .com domains on that list and 4 indiehackers bought it. 175 of them registered again.
A few of my favourites;
uibros.com emucast.com convies.com pingdeck.com huntely.com
Here is the second version. This time I've included all the products even the not featured ones (in total of ~230K product listings) and gathered around 4900 .com available domains. Put it into an AirTable with metrics like Backlink Counts, Search Volumes etc.
Here is a sneak peak.
