Features

  • No server or client: every connected computer can control the others.
  • Mix Windows and Mac: they connect the same way.
  • Shared clipboard and files: copy text and files between computers, or drag files across screen edges.
  • Easy pairing: computers on your network are found automatically; connect with a 4-digit code.
  • Matches your desk: drag computers and monitors on screen to where they really are.
  • Also: launch at login, keep connected computers awake, shut down all connected computers at once.
