PastePal is a good alternative - similar cross platform tool to Paste, but without the subscription. I recently looked through the options and settled on PastePal and keyboard maestro’s clipboard manager.
Yoink on iPhone and iPad. It’s the one app I’ve found that can collect pasteboard items in the background, like you can do easily on the Mac. It’s a bit clumsy due to iPhone/iPad limitations, but it works.
Thanks for pointing out PastePal. I also think I will drop Paste this year, not so much because it’s a subscription, but because there hasn’t been much development done on Paste, apparently, as updates are extremely rare. It’s one of those cases where you wonder what exactly does the subscription cover if not the perpetual development.
I’ve tried a few different ones over the years, currently I’m using Keyboard Maestro’s built in clipboard manager. PasteBot is my second choice, but I really don’t like running something extra when Keyboard Maestro is always running on every Mac.
