    Comments about Barrier as an Alternative to Synergy
    Comment summary: Barrier, a fork of Synergy, is praised for being an open-source, cross-platform solution with active maintenance. It provides an easy setup and works efficiently across Linux and Windows, requiring minimal adjustments. Despite the lack of Wayland support, users find it reliable and fast, emphasizing its function compared to the now less-updated Synergy. Development for Synergy has shifted towards the InputLeap project since February 2022.

    This is the only cross-platform solution I've found so far, and it's working a heck of a lot better than Synergy!

    No longer maintained as of Feb 2022, development efforts have continued under the "InputLeap" project on GitHub

    Last update from November 2021. Main developers moved to Input Leap. For now both Input Leap and Barrier are more or less at the same state, but going forward Input Leap might be the better choice.

    Comments about Mouse without Borders as an Alternative to Synergy
    Comment summary: Mouse without Borders offers features like drag-and-drop file transfers that some users prefer over Synergy, but its Windows-only support is a major limitation. Many users report setup ease and reliable performance; however, others face issues with installation bugs, inconsistent mouse sensitivity, and lack of cross-platform support. Overall, it is praised for its simplicity and effectiveness on Windows, yet criticized for not meeting the cross-platform capabilities Synergy provides.

    Fantastically easy to use, although only on windows computers so it's not always an alternative to Synergy (which I'm using right now, because Linux...)

    Mouse sensitivity is inconsistent across screens with varying resolutions. Adjusting settings for uniform sensitivity leads to discrepancies in mouse acceleration.

    It's an extremely reliable keyboard/mouse sharing program for Windows computers, with built-in encryption, a rather intuitive screen configurator for relative positions, and UDP or TCP communications. I've used it for over half a decade with great results. It's a pity that it doesn't work with other operating systems, but there's only so much that one programmer can do.

    It works great between monitors with different orientations and resolutions, which is not well handled by several other software, and the new version has a nice interface.

    Input Leap is software that mimics the functionality of a KVM switch, which historically would allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment.

    Cursr running locally to map the edges of disparate monitors. This enables the pointer to move between screens anywhere along the edge - not just where the OS sees the screen edges meeting up.

    Only real KVM for windows since it is the only product that let's you use the monitor of the connect computer to display windows of programs that are running on the primary computer.
