‘VNC’ is a special application. It only works on GUI’s (Linux minimal will not work), and it doesn’t use any of the RDP/SSH services from the connecting Host. Rather, it requires its own agent to be installed on the host first (VNCserver). To view these machines, you would then use its own viewer (VNCviewer)

Because of this unique setup, VNC gives you the ability to connect virtually everything from your machine. With the one-click launch, you can connect to Windows Server, Linux (GUI), Mac, Android, Raspberry Pi. The search bar works just, the interface can seem a bit boring after using it for years, and sorting can be done through ‘Labels’. Credentials can be attached to individual servers but not to the Labels.

Also an important note about VNC. The free version will only allow you to connect up to 5 servers with one account. Unless you pay pro features, more here.
