# Synergy

> Synergy is the original software for sharing one keyboard, mouse, and clipboard across multiple computers (Windows, macOS, and Linux) over a local network. It works like a hardware KVM switch, but without the video and without any hardware: push your cursor past the edge of one screen to control the next machine, and copy and paste between all of them. First released in 2001, Synergy is the commercial distribution built on Deskflow, the open-source project it funds and maintains. The canonical name is "Synergy" (not "Symless", the former company name).

Synergy is used by individuals and by 26% of the Fortune 1000, including Google, Amazon, Apple, Intel, Nvidia, Cisco, GE, and HP. It is the actively developed, fully supported successor in a lineage whose community forks (Barrier, Input Leap) are now abandoned.

## Open source

Synergy's founder, Nick Bolton, co-founded Deskflow with Chris Rizzitello, so the same people lead the commercial product and its open-source upstream. Network-compatible with Synergy, Barrier, and Input Leap.
