Comments and Reviews

   
Comment summary: Synergy, originally open-source, is criticized for being turned into a commercial product with numerous unfixed bugs. Users report issues like buggy functionality, dependency problems, and the requirement of a license key even for nightly builds. Many point out persistent bugs, especially in version 2, and some suggest alternatives like ShareMouse or Barrier. The transition to a payware model and the cloud feature have caused dissatisfaction among long-time users.

Works great with all systems (Linux(Ubuntu in my case), Windows, macOS). Amazing experience.

Only note: for Linux I had to add ports for firewall to not block them, but everything else worked just fine.

I've used Synergy on and off for over 15 years, so when I say "it's a buggy piece of crud and always has been", I know whereof I speak.

There are fully FIVE HUNDRED AND NINETY FOUR current unfixed bugs showing on Synergy's Github page, many of which have languished untouched for several months.

Don't waste your time. Especially on a Mac.

I seen to remember that whoever had the open source project complained loudly about the 'odd' requests from users. You know, like fixing this bug or that, and whining about not getting paid while insulting users over constructive criticism. I was a bit pissed off when it went commercial and pricing went way above and beyond making money. Most projects that go commercial have a 'free' version for hobbyists and education, and charge businesses for licenses. Haven't used it since it went commercial. Doesn't surprise me that it's buggy and hasn't really been updated all that well. Too bad. It had a lot of promise.

I’ve been using it since version 1. Sometimes it needs a bit of tweaking, but it’s invaluable.

fast support response

had issue with not being able to connect new computer to two other computers that were already connected with 3.5.1 Lite version. mistakenly thought i am forced to upgrade to 3.5.1 Max for this to work, which i did, and it was not the case, actually problem was my network misconfiguration on the new pc. support acted fast and refunded my upgrade without even me asking. thank you

This was a nice tool back then. Now you are supposed to have an account or even buy open source software from them. sucks. i went for barrier.

Synergy, critical workflow through a very flawed program.

Synergy was originally abandoned open source code that Symless picked up to further the project and ultimately commercialize it. Many years ago, the idea of having a home test lab and not having multiple keyboards and mice eating up desk real estate was a dream. You could ssh or rdp to your other machines but this isn't always the same as being in front of the machine. Synergy finally gave me a solution to many of my problems.

Synergy was expected to be buggy in the beginning because Symless were trying to start anew from old code. However, the software both improved and regressed during all these years. I won't go into all the various bugs I've encountered over the years as other posts give a better idea.

I believe most of the problems with Synergy are organizational. Questioning why developers want more money in a market that pays well. Giving current users a discount on the 2.x series but not refunding them when 2.x completely failed. Raising prices on already buggy software. Encouraging users, many of whom now depend on the software for work, to do bug testing. Who has time for that after eight hours?

I warned Nick (Symless founder) against going down the same road Parted Magic did when they put their product behind a paywall.

Overall Synergy is now mostly stable for my day to day use but I'd recommend trying Barrier first. Synergy is one of the few KM options available for linux.

Be careful what you paste into a terminal. Check what a command installs before running it.
