Best color palette generator?

Okay Internet people. I’m looking for a color palette generator where you can input one color (say with a hex value), and the generator produces one ore more palettes that would go with that color.

I’ve checked the great and merciful search engine and found these websites:

http://paletton.com/
doesn’t really generate a paletter unless I’m just doing something wrong.

https://coolors.co/
Does the trick, but is there an even better option.

https://color.adobe.com/
Meh!

There are other sites, but these two are the best I’ve found. Would love for us to create a good resource here. Please weigh in guys. Feel free to link to tutorials or anything you feel would help anyone looking for a good (free maybe) color palette generator.
