**Deskflow** is a free and open source keyboard and mouse sharing app.
Use the keyboard, mouse, or trackpad of one computer to control nearby computers,
and work seamlessly between them.

Deskflow acts as a software KVM (without video) that allows you to:
- Share keyboard and mouse input across multiple computers
- Synchronize clipboard content between machines
- Work seamlessly across different operating systems (Windows, macOS, Linux, BSD)

Deskflow software consists of a **server** (primary computer) that shares its input devices and **clients** (secondary computers) that receive and execute the input commands over a TCP network connection.

### Architecture Overview

Deskflow is built with a modular, cross-platform architecture:
