Cross-platform input sharing

InputShare

For people who work across several computers at one desk. InputShare lets one keyboard and mouse control macOS, Windows, and Linux machines, with clipboard sharing across the same setup.

One desk, several operating systems

It was built because aging alternatives often make compromises in speed, pointer accuracy, or capability across modern systems.
