Synergy is a software application developed by Symless. It is used for sharing a keyboard and mouse between multiple computers, and is useful in situations where several PCs are used together, with a monitor connected to each, but are to be controlled by one user. The user needs only one keyboard and mouse on the desk โ€” similar to a KVM switch without the video.

Partly open source and partly closed source, the open source components are released under the terms of the GNU General Public License, which is free software. The first version of Synergy was created on May 13, 2001, by Chris Schoeneman and worked with the X Window System only. Synergy now supports Windows, macOS, Linux, and other Unix-like operating systems.

Once the program is installed, users can move the mouse "off" the side of their desktop on one computer, and the mouse pointer will appear on the desktop of another computer. Key presses will be delivered to whichever computer the mouse-pointer is located in. This makes it possible to control several machines as easily as if they were a single multi-monitor computer. The clipboard and even screensavers can be synchronized.

The program is implemented as a server which defines which screen-edges lead to which machines, and one or more clients, which connect to the server to offer the use of their desktops. The keyboard and mouse are connected to the server machine.

  • Encryption
    The software supports SSL encryption, ensuring that data transferred between machines remains secure.
  • Clipboard Sharing
    You can easily copy and paste text and files between different computers, streamlining multi-computer management tasks.

Possible disadvantages of Synergy

  • Cost
    Synergy is a paid application, which might not be ideal for users looking for a free solution.
  • Initial Setup Complexity
    The initial setup can be complicated, especially for non-technical users, involving configuration of network settings and screen layouts.
  • Occasional Lag
    Some users have reported experiencing occasional lag or connectivity issues, particularly over Wi-Fi connections.
  • Security Concerns
    Despite SSL encryption, there are potential security risks involved in transferring data over a network, especially in untrusted environments.
  • Compatibility Issues
    There might be occasional compatibility issues with certain applications or specific versions of an operating system.

GitHub Codespaces features and specs

  • Instant Setup
    GitHub Codespaces allows for quick setup of development environments, enabling developers to start coding within minutes.
  • Consistency
    By using Codespaces, all team members can work in consistent development environments, avoiding the 'works on my machine' problem.
  • Scalable
    Codespaces can easily scale up or down resources based on the needs of the project, offering flexibility in resource allocation.
  • Integrated with GitHub
    Seamless integration with GitHub means that Codespaces takes advantage of all GitHub features like pull requests, issues, and workflows directly within the development environment.
  • Customizable Environments
    Developers can define the configuration of their development environments using devcontainer.json files, making it easy to set up tailored workspaces.
  • Remote Development
    Codespaces allows developers to work from virtually anywhere without needing to rely on the power of their local machines.

Possible disadvantages of GitHub Codespaces

  • Cost
    Using Codespaces incurs a cost based on compute and storage resources, which can add up, especially for larger teams or more intensive projects.
  • Internet Reliance
    Codespaces are cloud-based, so a stable internet connection is required. Any disruption in connectivity can hinder development progress.
  • Customization Limitations
    While customizable, Codespaces may not support all specific or advanced development setups or niche tools as effectively as local environments.
  • Performance Variability
    Performance might vary depending on the selected instance type and current load on GitHub's infrastructure.
  • Dependency on GitHub Ecosystem
    Codespaces are tightly integrated with GitHub, which could be a downside for teams that use other platforms or who prefer a more platform-independent solution.
  • Learning Curve
    Developers unfamiliar with cloud-based environments may face a learning curve when first transitioning to Codespaces.

  • Two computers, one monitor, zero fiddling โ€“ Alex Plescan
    I did something similar last year with a monitor without built-in KVM but with good DCC support (Ultrasharp U3417W) and Synergy [0]. I use Synergy as part of my desk setup already, but needed a way to view the UI of a normally headless machine.

    I use a software called Synergy. https://symless.com/synergy I have one keyboard and mouse connected to one "host" machine, and two machines connected as clients.

  • OpenCode Hit 140K Stars. Why Terminal Agents Won 2026.
