Input Leap is the community-maintained fork of Barrier — a solid, cross-platform open-source KVM. ShareCursor covers the same core idea for Mac↔Windows, but is encrypted by default, ships file transfer and clipboard images, and uses zero-config discovery so you never type an IP.

​
Which should you pick?

  • Choose ShareCursor for Mac↔Windows if you want encryption on by default, file transfer, clipboard images and mDNS discovery out of the box, with the lowest input lag.
  • Choose Input Leap if you need broad Linux support and a very mature, multi-platform codebase.
Input Leap (and Barrier before it) proved how useful a software KVM is. ShareCursor is the newer, security-first take focused on Mac↔Windows: a UDP input path (~6 µs transport overhead), encryption on every channel, clipboard images, file transfer, and mDNS discovery.
