This post is a short summary of the differences between the Linux and the Windows versions of Syncovery.
The main difference is that the Linux version uses a browser-based GUI. If you run it on your own desktop, enter localhost:8999 to open the Syncovery GUI.
The GUI itself is very similar to the Windows and macOS version, although the web GUI is not quite as powerful and rich in features.
But the Program Settings and all the many settings in each profile are all there! So the Linux version is really just as powerful as the Win/Mac desktop ones. Except that support for MEGA is missing on Linux.
Here’s a screenshot of the Web GUI:
