CopyQ

This clipboard manager has a hidden gem. Synchronize (Preferences -> Items). I use CopyQ on Mac, Windows and Linux systems so being able to sync clipboard items between them is very useful. This wonderful feature allows you to setup a folder that can be shared across systems (I use a folder in Dropbox). Now if I want to share a clipboard item between systems I just move it to the "shared" tab and it syncs automatically. Beautiful!!!

I like it because it saves me a ton of copying and pasting. Brilliant APP!!

Nice that it works offline & stores images. When copying a line of text inline with icons/thumbnails, a sort of placeholder is put vs with Ditto where the link anchor text shows.

Best one of the bunch. Apps I've tried: Maccy, Flycut, Jumpcut, and many others from the App Store. Only CopyQ lets me select a number of clippings to paste all at once. The others can only paste one at a time. Personally, this is a needed feature. Also, CopyQ is just more robust all around, has the features others offer and then some (customization is S-tier), and doesn't feel like a quick side project by a dev. One major con: it's hard to make the dropdown menu appear in one click. You have to click the icon a few times before it comes out. What's up with that? This is one big minus that the others have over it by a mile; otherwise, an excellent app. -on macOS Big Sur
