   Barrier vs Synergy Comments

   Top Positive Comment by Iaian7 · Mar 27, 2019

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

   Top Negative Comment by kylefmohr · Jul 29, 2023

   No longer maintained as of Feb 2022, development efforts have continued under the "InputLeap" project on GitHub

   Positive comment by mazee · Feb 25, 2023

   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.

   Input Leap

    35 likes

   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.

   Input Leap vs Synergy Comments

   Positive comment by CountBuggula · Mar 6, 2025

   It's the currently maintained fork of the original open-source version of Synergy.

   Positive comment by kylefmohr · Jul 29, 2023

   A fork of Synergy from back when it was open source, that is actively being developed, and works cross-platform.

   Has all the features I need from Synergy -and- enables me to map the sides of non-matching displays for smooth screen-to-screen pointer movement

   x2vnc (win2vnc) vs Synergy Comments

   Negative comment by Guest · Nov 21, 2022

   This does not actually replicate the functionality of Synergy

   Positive comment by Guest · Mar 22, 2016

   While the description is a little vague, they seem to imply that your keyboard/mouse input is sent to another PC when you move your mouse into a tiny window on either PC.
