But, in my opinion, it has one significant drawback - it has to be installed and has not so few dependencies.

Thus if, for example, the objective is to transmit a single send.firefox.com URL from one machine to another, then installing Maic Wormhole on both of these machines is an overkill.

I usually resort to manually typing data on the second machine (a binary data block could be base64 encoded beforehand).

Do you know any software or services that could facilitate such scenarios (you need to transfer a small amount of data from one machine to another but it's impossible to use ssh, rdp, clipboard, etc.)?
