I don't mean to be negative, it's a great looking site and works well, but there are a lot of these kind of tools popping up on show hn that don't really provide that much value. It's a cool convenience for sure but there really isn't much value. It's great as a practice project I guess but there are so many of these on show hn these days, dunno if anyone else feeels the same
Liked some of the suggestions, but the way they're displayed is not very easy to read. My suggestion is having the domains divided in columns with more spacing, much like leandomainsearch.com.
