ShareClick vs Mouse Without Borders

A free, open-source alternative to Mouse Without Borders that also works on Mac. Share mouse, keyboard, clipboard and files between Mac and Windows. Encrypted.

Mouse Without Borders is a great free tool from Microsoft — but it is Windows-only. If you need to share one keyboard and mouse between a Mac and a Windows PC, ShareClick does it: open source, encrypted by default, with clipboard and file sharing built in.

Which should you pick?

• Choose ShareClick if either machine is a Mac — Mouse Without Borders can’t help there. You also get open source, encryption on by default, and zero-config discovery.
• Choose Mouse Without Borders if all your machines run Windows and you’re happy with a closed-source Microsoft tool.

Mouse Without Borders is polished and genuinely free, but it never left Windows. ShareClick brings the same “one keyboard & mouse across machines” idea to Mac↔Windows, with a UDP input path (~6 µs transport overhead), encryption on every channel, and mDNS discovery so you never type an IP.
