alt Hacker News> the #1 thing I miss right now is Barrier (Synergy) for using my macbook from my linux desktop)
It's admittedly tough to keep up with all of the forks that have happened, but the current iteration, Input Leap, has worked for this for me for years now
That's not even the most recent iteration, there's also Deskflow now which is maintained by the main Synergy developer and a very active independent dev. Works fine on Wayland afaik. Also has a wiki page with the history of all the forks!
