### "A very robust and free option to remote connections"

June 8, 2021

5.0

Pretty interesting solution, I have used it on my former company to connect through 30 operations companies, with different sizes of bandwidth, and it manages it very well, and the price, for be free, is one of the most attractive things about this one.

Pros

It is free, has a bunch of very good resources, the connection is pretty good, works very well even on poor connections, the bandwidth control is one of the best which I have seen. Therefore, it has some features such as file sharing, chat, and the deployment and configuration are pretty easy on both sides: administration and clients.

Cons

Do not have so much cons about it, just on the support side, because the software is free. However, it has a good documentation to follow, but you need to have some network and server side skills.

Reason for choosing UltraVNC

The company did not want to spend money with a remote solution, and by that time, Lync (which today is Microsoft Teams and was Skype for Business), was not the best solution for remote connections.

### "Ultra VNC - fast VNC with high compression"

April 7, 2022

5.0

Ultra VNC enabled us to remotely administer a number of customer servers that only had dial-up access, without the constant drop-outs that we experienced using some other commercial software available at the time. This has saved them time and money repeatedly.

Pros

Installation and configuration for UltraVNC was super simple. Our remote clients often had very un-reliable and slow connections, but UltraVNC was able to cope with it with it's high compression algorithms to enable to efficiently manage remote systems and provide support.

Cons

There were odd occasions where the server would not run correctly as the driver did not load, but was not often an issue and more likely to be a PC issue.

Better compression and connections for poor quality network access via dial up.

### "UltraVNC - More secure options availbable."

January 27, 2022

3.0

UltraVNC sets a static password when deployed. In addition the system must have firewall rules for accessibility this leaves the administrator with a difficult to change password. The requirements for firewall rules mean that for remote access I would either need to have a VPN tunnel to secure remote access or lower security at the corporate firewall. Alternatively there are many web hosted secure services that are low cost.

Pros

The most advantageous feature of this software is that it is free of cost and can be installed as a service allowing systems to be accessible at every reboot.

Cons

Fixed password and limited accessibility makes it an undesirable option for corporate use.

### "UltraVNC review by Support Agent"

December 3, 2020

5.0

I would recommend UltraVNC for use to anyone who has a network of a couple PC's, as it is easy and fast to connect to the Remote PC and check what is happening with it. In case some files need to be change, UltraVNC has that ability as well, which can speed up troubleshooting process as well.

Pros

I like using this tool as I can easily connect between PS's on the same network ( in my case ) and I can check what is happening with each PC in timely manner. Also, I am able to share files between these PC's which can be really useful when I need to edit and upload some configuration file for instance. Of course, this connection is always password protected.

Cons

UltraVNC sometimes tends to bug, which is why I need to path through Services to the affected PC and check if there was any issues with it's Services. It would be nice to have a feedback, whenever appropriate Service is not running properly or it has some issues.

Switched from

[RealVNC Connect](https://www.capterra.com/p/173752/VNC-Connect/)

I made a switch from VNC Connect because of my customers, who back in the time preferred another type of connection ( TightVNC, UltraVNC and so on ).

### "Does What Is Says On The Tin - Solid VNC Software"

May 5, 2022

5.0

My experience has been great, I've used UltraVNC in my personal life for many many years, but only for around 6 months within my business. It stands up well compared to other VNC software, has a low latency and seems to be very stable, with little to no crashes. I'd recommend it if you need software for VNC.

Pros

I've never had any issues with UltraVNC, it works as it should. The automatic clipboard synchronization is a simple, but well received feature that lots of similar software doesn't seem to include.

Cons

The only thing that I would list as a con about the software, is the need for port forwarding on the machine acting as the VNC server.

Reason for choosing UltraVNC

I chose UltraVNC overall, due to it having the most stability and little to no latency issues.

### "Great VNC client"

June 3, 2025

4.0

Pros

For VNC it is pretty solid, much better than a less feature-rich client such a tightVNC especially when it is your primary remote access tool

Cons

not suitable for remote support in many cases as you need to connect to a client VPN before you can VNC to their internal systems, meaning multiple connections as once is not always possible, but this is more of a limitation of the protocol than the client per se

### "One of the first, but not the best."

February 23, 2022

4.0

I'd recommend other VNC softwares instead of UltraVNC.

Pros

First of all, UltraVNC is totally free: it is developed under a GPL license which allow the users to implement and develop its code to realize a better software over time. The interface is quite "old style", it has everything you need to start and work out your remote session.

Cons

The interface: absolutely "old style" and totally out of time. It's a PRO on one hand (read previous pros), but on another hand it's a total CON if we think about the modern app and software interfaces. The usability is not as good as it should be for newbies.

### "Small but functional VNC tool"

November 28, 2020

5.0

Easy to use solution, no worries regarding licensing or user session management, easy to install.

Pros

For someone that uses remote servers for their work having trustworthy vnc connection is crucial. I used Ultra VNC for half year and I can say that this is great solution if you want simplicity. It’s open source, works even when connection is slow, very easy to navigate, you need only server name and password to connect.

Cons

I’d prefer to have some optimizations for really slow networks for example do not refreshing the screen or refreshing partially.

### "Great open source solution for remote computer management and diagnostics"

May 6, 2020

4.0

The UltraVNC Single Click version has been great to provide to my clients without having to worry about licensing issues. Many of them are computer novices so not having to talk them through installing more complex software and changing network settings has been a real time saver.

Pros

UltraVNC is a great open source solution for remote desktop connections and being free for commercial use means big savings if you've got a lot of users that need occasional support. The software is small and easy to install and includes a variety of options to suit different Internet connection speeds. There's also a Single Click version that allows you to create a custom executable that can be distributed to customers preconfigured to connect to your IP address which saves them needing to configure the firewall at their end to support incoming connections.

Cons

Compared to some proprietary software like Microsoft Remote Desktop and TeamViewer the screen updates appear to be a little slower and there can be occasional glitches that need a screen repaint. While not a big deal for remote support incidents it may be worth looking at other options if you're intending working over a remote connection for extended periods of time.
