I was thinking it would be nice to quickly send the clipboard to another machine without direct network connectivity. Then I thought why not piping it? Not just the clipboard, but any data.

    $ xclip -sel c -o | clipipe send
    $ clipipe receive {code} | xclip -sel c

Implemented it using Python for both the CLI and server (FastAPI). Please checkout https://clipipe.io for more info and https://github.com/amirkarimi/clipipe to see the source code.
