Struggling with separate peripherals for your Mac and PC? Is your desk cluttered with cables and devices?

“Beamer: Effortlessly share your keyboard and mouse between Mac and Windows PCs over your local network. Simplify your cross-platform workflow with this open-source software KVM.”

The Essence

Beamer is an innovative open-source software KVM (Keyboard, Video, Mouse) solution. It's designed for users who work with both macOS and Windows computers simultaneously but prefer the convenience of a single input device setup. This project leverages your local network to create a seamless bridge between your different operating systems, allowing for unified control.

Capabilities

Beamer eliminates the need for multiple physical keyboards and mice, reducing desk clutter and enhancing productivity for developers. It enables bi-directional control, letting you move your cursor and type across a Mac and a Windows PC, complete with clipboard synchronization for effortless copy-pasting between environments.

Replaces

This project serves as an excellent open-source alternative to commercial software KVMs like Synergy, which often come with subscription fees. It also provides a digital, software-based solution that can replace traditional hardware KVM switches, which typically require extra cabling, take up physical space, and often lack features like clipboard sharing.

Editor's Highlights

  • Share a single keyboard and mouse across Mac and Windows PCs
  • Achieve bi-directional control between connected computers
  • Seamlessly synchronize clipboard content across operating systems
  • Utilize your local network for stable and flexible connectivity
  • Benefit from a lightweight, entirely open-source Python-based solution

How It Compares

AlternativeMain StrengthMain Weakness
SynergyCross-platform (Linux, Windows, macOS) and feature-rich with a polished UI.Proprietary, paid software, and can sometimes be complex to configure.
