What's the best multi-device clipboard manager for Mac?

I use Paste (like you mentioned). I'm obsessed with it. I used Flycut before. Nothing I've tried compares to Paste though.

I'm a Copied fan. It's a no-fuss app that gets the job done. You can sort your clips into different categories, and the app provides two kinds of extensions you can use on iOS.

I'm a huge fan of Alfred, I use it all the time. It's super customizable and you can pretty much get it to do whatever you want.
