## Which should you pick?

* **Choose ShareClick** if you want it **free and open source**, encrypted by
  default, with the lowest input lag and no license to manage.
* **Choose Synergy** if you need first-class **Linux** support and paid
  commercial support, and don't mind the license fee.

Synergy is a mature, respected product — its open core (Deskflow) is excellent.
ShareClick is the newer, free-and-open option focused on Mac↔Windows with a UDP
input path (\~6 µs transport overhead), encryption on every channel, and
zero-config mDNS discovery.
