Ranked in these QuestionsQuestion Ranking
Pros
Pro Simple to setup
Pro Easy to use
Pro Free
Pro Add notes or tags to items
Most effective with stacks that don't automatically delete the oldest members, tags and notes allow you to use CopyQ as a personal database for important information with easy access and retrieval.
Pro Cross-platform and cross-DE
CopyQ supports all major Linux desktop environments (including KDE Plasma, GNOME, Xfce, etc.), Windows and MacOS X 10.9+.
Pro Can sort and store based on content type
Built-in support for text, HTML, images or any other custom formats, allowing for type-based clip stacks that each have their own custom actions (open images in a photo editor, open URLs in a browser, etc.)
Pro Browse and filter items in history
Quickly locate that snippet you copied months ago but don't recall precisely what it was.
Pro Comes already integrated with the one of the best Linux desktop environments
It's a part of Plasma 5 which is one of the best Linux desktop environments currently, so it has complete integration and is already included with the basic packages.
Pro Can be configured to work as you like
Length of the history, persistence between sessions, what to do with trailing white spaces, basically whatever you could wish to change is configurable.
Pro Integrated support for MIME-based Actions
And you can configure any other actions with regexps based on content
Pro Pre-configured button to create a QR code out of any clips
If you're not already using KDE Connect to exchange clipboard entries with your mobile devices, this one is a lifesaver. It's also handy when someone else needs to copy one of your clips.
Cons
Con impossible to quit/start copyq via script
Con In linux, it sometimes does not react to shortcuts
Also buggy when hiding.
Con Sometimes copies filtered entries in between selection
Con Can't export images in bulk
Con Slow with many entries
Con Slow to place selected content on editor
Takes a while to place the selected text into the editor.
Con Since it's part of Plasma it might not be the best choice for other DEs/WMs
No complete integration, will pull in a lot of Plasma dependencies....
