The first and immediate difference for me is the ability to recall the name. I can recall Postman/Insomina fine, and now for API Parrot. I'm never going to be able to recall mitmproxy2swagger.
Ha! Nicely played. That was out of purely laziness. I don't like using one handle across sites, so I take the first 8 chars of (New-Guid).ToString() and then dump it in my password manager.
As someone who uses mitmproxy and swagger quite often, I actually think the name isn't so bad. I haven't even looked at the readme but I already know what it does, how to run it and what output to expect.
I often forget the name of things, sometimes even the big ones. GitHub search is one of the primary ways I rediscover them. "reverse-engineer API" returns mitmproxy2swagger as the third result, and this is how I found it last time I needed it.
It is a bit frustrating when a project on GitHub doesn't have good tags or searchable keywords, making it harder to find.
Unfortunately, names matter.
