8 Best Free VNC Software For Windows

Here is a list of best free VNC Software for Windows. These VNC or Virtual Network Computing software are desktop sharing software which let you control a remote computer. These VNC software use Remote Frame Buffer Protocol (RFB) to control other systems. You can use mouse and keyboard of a client computer to perform any task on a remote computer. In some VNC software, you can also collaboratively work with other members and perform tasks on a remote PC. Overall, all of these freeware are quite easy to use once the connection between remote and client computer gets established.

In order to establish the connection, you need a VNC Server in the remote computer and a VNC Viewer in the client computer. Some of these software have both VNC server and viewers, hence you need to install the same setup on both client and remote computers. However, many software only come with a VNC viewer and hence required VNC server of other VNC software like TigerVNC, TightVNC, etc. As VNC server is installed on the remote computers, so you need to set up a password and other network settings before starting the server. After starting the server, go to the client computer and provide IP Address and Server Password of the remote computer to establish the connection. After the successful connection, you are ready to control the remote computer.

RealVNC is a free VNC software for Windows. This software comes in two parts namely VNC Connect (server) and VNC Viewer. You need to install the VNC connect to the remote computer which you want to control. And, install VNC viewer to a computer from where you want to control a remote PC.

After that, select the thumbnail of the remote computer and connect it to your PC. Now, you are ready to control the remote computer.

You can quickly toggle between one remote computer to other remote computers just by double-clicking on the thumbnails of the connected remote computers.

With the help of this software, you can view the whole screen of the remote computer on your system. Plus, you can use your mouse and keyboard to perform tasks on the remote machine.

Overall, it is a very good VNC software as it gives you a lot more options than similar other software.


TightVNC is a free and open source VNC software for Windows. It is another Virtual Network Computing software through which you can access and control a remote machine. You can easily perform any task on the remote machine just like you perform tasks on your computer. Additionally, this freeware also allows direct data transfer between client and remote machines. Besides this, you get some other tools to adjust the view like Scale in, Scale-out, Full-Screen Mode, etc.

This software requires a little bit of setup before it gets ready to be used. Let’s take a look at the setup process of this software:

  • The first step is to download TightVNC software in both client and remote server computers.
  • After that, install this software on both computers. During installation, this software asks you to specify Remote Password and Admin Password. These both passwords are needed to be set up on the host computer, which will later be used by TightVNC Viewer to control remote PC.
  • After installation, run the TightVNC Server on the remote desktop computer and run TightVNC Viewer in your system (client).
  • TightVNC Viewer asks you to enter the IP address of the remote computer. As soon as you enter the IP address, this software asks you to enter the Remote password of the host computer. Simply provide the Remote password in your TightVNC viewer to start controlling the remote computer.


TigerVNC is another free open source VNC software for Windows. It is a high-performance VNC software that helps you launch and interact with the user interface of a remote machine. This software is powerful enough to run 3D and video applications. Like other VNC software, it also gives you complete freedom to access and run any application of a remote computer without any restrictions. However, this doesn’t let you directly transfer data between server and client computers.

TigerVNC software mainly consists of two parts namely TigerVNC Server and TigerVNC Viewer. Both of server and viewer come in the same package, hence you need to download and install TightVNC setup on both client and server computers. After the installation, configure the TigerVNC Server in the remote server computer. In order to do that, use the Configure VNC server software that comes with this software. In the configuration, you can select security encryption of your choiceauthentication method, port number, etc. along with the server password, etc. After the setup, run the TigerVNC Server. Now, on the client side, you need to run TigerVNC viewer. To connect to the remote computer, you just need to provide the IP Address along with the right server password. Once connected, you can freely control the remote computer with ease.


EchoVNC is the next free open source VNC software for Windows. It is a secure VNC software through which you can control a remote computer. This software gives you the complete control over the remote computer and you can perform any task on the remote machine from another PC without any restriction. This software also provides some basic options like full-screen mode, send Ctrl+Alt+Delete function to host computer, shortcut to open the start menu of the host computer, etc. Overall, it is another handy VNC software that you can use to control remote computers.

This software comes with the EchoVNC Viewer that can also be used as a server. However, during testing, its server didn’t work properly. Hence, I have used the VNC server of TigerVNC software. In order to establish the connection between Remote and client computers, you need to provide IP Address along with the TigerVNC server password of the remote computer. Once connected, you can immediately view and control the remote computer on your system.


VNCRobot is a free, Java-based, portable VNC software for Windows. Through this software, you can connect to any remote computer running VNC server. This software does not have its own VNC server, due to which you need to use an external VNC server like TigerVNC Server, UltraVNC Server, etc.

Like other similar software, you can use it to control the remote computer with your system. It gives you complete freedom to perform any task on the remote computer that you want. It also comes with a view mode that only lets you monitor the screen of the remote computer.

In this software, you get a Script Editor along with various script command generator keys to perform various activities on the host computer with the help of scripts. You can easily generate script commands like screenshot, waitfor, compareTo, etc. using the various shortcuts present on the toolbar. The generated command will automatically be added to the script editor. Now, to run the commands, you just need to press the Execute Script Button. All the tasks specified in the commands will execute on the host computer.

As this software can connect to any VNC server, hence just install any VNC server on a remote computer and specify the authentication password in it. After that, launch this VNCRobot software in client computer and provide both the IP address and server authentication password to establish a secure connection.


mRemoteNG is the next free open source VNC software for Windows. It is a multi-protocol VNC software and hence, it can use protocols like RDP, SSH1, Telnet, rlogin, etc. to establish the connection with a remote computer. Using this software, you can easily establish the connection with any VNC server running on the remote PC. However, you need to provide the correct IP Address along with the server password in mRemoteNG (on client’s computer) to establish the connection. Once the connection gets established, you can view the display of remote computer in your system. You can run any application, browse internet, or perform any other task on the remote computer with ease.

In this software, you can maintain multiple remote server connections. Plus, you can also quickly jump between multiple connections. All the saved connections can later be saved or exported as an XML file. Besides this, features like screenshot, SSH file transfer, port scan, quick connect toolbar, etc. are also available.


TurboVNC is another open source VNC software for Windows. It is a high performance and 3D friendly VNC viewer software. It is fully compatible with TightVNC software i.e. it can connect with the TightVNC server of a remote computer. As it does not have its own server, hence server of TightVNC is necessary to establish connection. And, you need to provide the IP Address of host computer and Server Password to establish the secure connection.

After the successful connection, you can view the screen of a remote computer on the TurboVNC interface. You can use your mouse and keyboard to control and perform any task that you want to. Apart from just controlling the remote PC, you can also directly transfer files between client and host computers. More useful options that this software provides are Save (to save all information related to connection), Disconnect (to disconnect current connection), New Connection (to establish a new connection), etc. In general, it is quite a simple and easy to use VNC software.
