This is an open-sourced keyboard and mouse sharing utility that allows users to easily control multiple computers with a single set of keyboard and mouse. Originally, it was the open-source community version of the commercial software Synergy (formerly known as synergy-core). Now, it has been fully open-sourced as the upstream project of Synergy, removed commercial features, renamed, and its ease of use has been slightly reduced, but it has become more friendly to developers, supporting clipboard sharing, multi-device control, and cross-platform capabilities.
