“Are you seriously complaining about the price of power, when you’re sitting in a home worth hundreds of thousands”?

Same energy.

For a combination of tools already available elsewhere (command line/existing sites), maybe?

The value is in the convenience of NOT having to spend the time researching, bookmarking, and remembering all those tools you use. That is the calling of software developers right? To abstract complexity so the other person doesnt have to worry about "this"? All businesses are born out of creating convenience for someone else who values time more than experience (in that particular thing).

$25 for this app might save you hours of work, hundreds or thousands. Just like $25 for a half tank of gas will save you a few hours from getting to where you want to go.

50 is as expensive or inexpensive as you want it to be considering you are buying a tool for a specific purpose.

It’s also competing with stuff which is free.
