qStudio looks very cool and im right in your target demo - and I hate to complain about free but just a bit of feedback: jar on mac is a lot of friction to be able to try it. I just spent about 5 minutes downloading and trying to get it to work - mac says it cant open because its from an unidentified developer, I went into security to get it to open anyway, it gave me another scary warning and then it still couldn't launch because I dont have a jvm installed somehow?
I'll probably try again later because it really does look cool and as much as I absolutely love my intellij/datagrip I'm always looking for alternatives and have thought several times about building a tool with these automatic analysis tools built in.
