UltraVNC is nice to connect to hosts while on the same network. However, you are unable to tell your parents to install this and connect to them.

Top Positive Comment by ChaosDrop · Apr 21, 2017
For users who know what they are doing TightVNC is a great way to control systems remotely.
Top Negative Comment by Guest · Oct 20, 2016
TightVNC requires server configuration and port forwarding. Too complicated for the average remote client who uses Team Viewer for remote support.

it is easy to connect to virtual computers very nice
Top Negative Comment by Guest · Jun 6, 2018
Remmina is a great RDP or VNC client. These are already listed as remote desktop technologies. Let's be clear the main advantage of TeamViewer (and LogMeIn) is that the remote computer only needs an Internet connection. No port forwarding required.

Positive comment by Guest · Dec 26, 2017
DWService is much lighter, able to use even without installation, more options, web UI, also it is open source!
Positive comment by tuqueque · Mar 8, 2021
It's open source, free and more privacy respecting than the commercial counterparts.
Comment by al huber · Nov 25, 2021
Sounds great at first glance. But as always, there is a catch. Yes, the software is open source, but limited in bandwidth, if you want more speed you have to subscribe. And that can cost up to 100 € for 50 Mbps maximum bandwidth per month, 1200,- € or 1346,49 $ per year. Then better use a professional solution like Teamviewer or Anydesk.

It's the best open source alternative. It doesn't require port forwarding on client side. Just send the client the file and they press connect. That's it.

X2Go vs TeamViewer Comments
Positive comment by hansolo1988 · May 29, 2017
Very good if you're in Linux to Linux use cases.
Positive comment by elrey741 · Mar 1, 2020
Really awesome for Linux users to remotely connect to their computers through a secure connection. Allows for transmission of audio from the client, and works really well even with slow connections. To summarize: secure by default (because using ssh), good even in low latency, good for presentations, and best alternative to RDP for linux users.

Works remarkably good and it has sound as well.

Aspia is great for direct connections on the same network. It will also work for public IP connected devices, but needs no settings to be changed for local network connections.
Positive comment by Guest · May 25, 2020
My purpose was to have a tool to connect to a computer in the same private network that mine so i did not want the traffic to go outside home. This makes for me aspia the best alternative from the others ones because it was the simplest to to install: no dependencies just run
