Telltail [1] lets you share clipboard between your devices. If you've used or ever known about Apple's Universal Clipboard, it is quite like that. It uses Tailscale [2] to achieve this.
I must tell you that setting it up requires you to have some familiarity with the terminal (which already comes installed on your computer).
I've written a blog post on how I came about working on it and the iterative process that went behind it. You can read the post here [3].
The instructions to install Telltail can be found here [4].
It is a personal project of mine and is not affiliated to or promoted by any org. Hopefully with discussions and contributions we could add support for more OSs.
