    • It's a fork of the original version and is maintained. amenthesNov 2020 • 1 agrees and 0 disagrees Disagree   Agree
    • It just works, can be set up very fast and works perfectly Guest • Aug 2020 • 1 agrees and 1 disagrees Disagree   Agree
    • Is free and open source, works perfectly between my Linux machine and Windows laptop, other than entering an IP and dragging a monitor icon, practically no setup was needed Guest • Apr 2020 • 2 agrees and 0 disagrees Disagree   Agree
    • Sleek, fast, secure and open. No magic behind the scenes and it Just Works™. Can't recommend this enough! Guest • Apr 2020 Disagree   Agree

    • This is the only cross-platform solution I've found so far, and it's working a heck of a lot better than Synergy! Iaian7Mar 2019 • 7 agrees and 0 disagrees Disagree   Agree
    • It is a fork of the original synergy tool Guest • Aug 2019 • 4 agrees and 2 disagrees Disagree   Agree
    • It's open source and works flawlessly ! Guest • Sep 2019 • 2 agrees and 0 disagrees Disagree   Agree
    • Cross platform, clipboard support, easy and functional Guest • Sep 2019 Disagree   Agree
    • Cross-platform, open source, and under (at least somewhat) active development. Barrier is what Synergy used to be, many moons ago. Guest • May 2019 • 1 agrees and 0 disagrees Disagree   Agree
    • Still no Wayland support, but it works well otherwise. Guest • Aug 2019 Disagree   Agree
    • The key draw of Synergy was the true multi-platform approach ie BSD Linux mac and win are supported, which only this one can boast of. Being a fork of synergy itself a fork of cosmicSynergy this is no suprise but this team DO have binaries/installers ready to download though it is not updated often. idlesHandJun 2018 • 4 agrees and 0 disagrees Disagree   Agree
    • Its free, has SSL and do not come with bugs with some keys not behaving correctly. p3kjarosJan 2019 • 3 agrees and 1 disagrees Disagree   Agree

  • Mouse without Borders

    Mouse w/o Borders makes you the captain of your computer fleet by allowing you to control up to 4 computers from a single mouse and keyboard.

    • Not cross-platform. Useless to me. Guest • Apr 2020 • 4 agrees and 2 disagrees Disagree   Agree
    • Buggy installation. "Link" button does not work half the time. Would not connect even with correct code and computer name, on the same network. Guest • Nov 2020 Disagree   Agree
    • Platform support is lacking significantly. Guest • Jul 2019 • 9 agrees and 2 disagrees Disagree   Agree
    • Better than Synergy in that you can drag and drop files between computers. But... It's Windows only. So now other ecosystems allowed. Guest • Oct 2019 • 4 agrees and 1 disagrees Disagree   Agree
    • Fairly easy to set up, does everything as advertised. Guest • Nov 2019 Disagree   Agree
    • Code can be copied by clipboard just not from installation but later on u can, otherwise It works almost perfectly(slighter delay) and bit unfinished( cant delete computer, cant rename computer) i use 3pc one of them has two screens and gave me what i wanted. So overall 4,5/5 :) Guest • Sep 2019 • 0 agrees and 1 disagrees Disagree   Agree
    • Lack cross-platform support which is a core feature of Synergy. Guest • Sep 2019 Disagree   Agree
    • Windows-only? Is this a joke? Synergy is unique in allowing cross-platform control, so to say this comes close to meeting the requirements is a stretch. g0tmkApr 2019 • 8 agrees and 5 disagrees Disagree   Agree
    • Works like a charm, all the media buttons and all. Only flaw, the auth key isn't a copyable text so you have to copy it by hand and it's a bit long. Other than that, it's just right. Guest • Jan 2019 • 2 agrees and 0 disagrees Disagree   Agree
    • Does pretty much the same exact thing. The only difference I can think of is I don't know if MwB uses SSL encryption, which you can get on the Pro version of Synergy/ Guest • Sep 2017 • 1 agrees and 1 disagrees Disagree   Agree
    • It provides the same functionality which I need Synergy for right now. Windows-only is a clear limitation, but won't impede all users. Guest • May 2017 • 5 agrees and 4 disagrees Disagree   Agree
    • 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...) Guest • Jan 2017 • 9 agrees and 4 disagrees Disagree   Agree
    • Easy to set-up. Simple to use. Works. Guest • Jan 2017 Disagree   Agree
    • Is free, from Microsoft and works amazing with my 3 computers Guest • Jul 2016 • 6 agrees and 5 disagrees Disagree   Agree

    • As its suppose to be free but its really NOT, only for 2 screens not even 2 computers, so if u have a laptop with second scra and another PC with one ur done and not nicely, works for cca 5 min a than kick out or pay, its not even possible to to use only one of those screens.

    • It's very reliable, and the double tap to switch screens is great. Clipboard sharing works well too. The little window to show status helps when you have multiple monitors. Guest • Jan 2019 Disagree   Agree

Many years ago I got the free version running after a long hassle and it works flawless. I will never touch or update anything, buggy as hell.
