Can I launch RealVNC Viewer from a link on a web page or program using URIs?


Yes! Starting in version 6.22.826 onwards, RealVNC Viewer installs a URI handler that can be called from other programs, like web browsers, to launch a connection to a RealVNC Server using RealVNC Viewer.

What connection string format does the URI use?

The connection string format to launch a connection using a URI is below. The URI handler does not accept any additional parameters other than the RealVNC Server address.

Cloud Connections

com.realvnc.vncviewer.connect://<cloud server ID>

Direct Connections


Direct connections are only available on certain subscriptions.

How do I find connection address(es) for my RealVNC Server?

You can find the connection information for RealVNC Server both through the GUI and at the command line.

Using the RealVNC Server GUI

To find the connection address(es) using the RealVNC Server GUI, first open the RealVNC Server GUI using either the Start/Applications menu, or by double-clicking the RealVNC Server icon in the taskbar.

Once the GUI opens, expand the Other ways to connect section which will list the cloud server ID (all subscriptions) and/or IP address(es) (subscriptions that include direct connections).


Using the command line

Starting in version 6.11.0 you can query RealVNC Server for the cloud server ID on the command line. To do so, look for the ServerId line after running the appropriate command for your platform below.

Windows (elevated/administrator access required)

"C:\Program Files\RealVNC\VNC Server\vncserver.exe" -service -cloudstatus


sudo /Library/vnc/vncserver -service -cloudstatus


sudo vncserver-x11 -service -cloudstatus

  • This doesn't work on mobile. What is the URI to launch the mobile version? (even if it doesn't include a specific connection)

  • I'm using VNC Viewer v7.0.1 with an enterprise account on Win10 Pro.
    Using a formatted link like this
    doesn't do anything. What am I missing?
    Do I need to enable the VNC Viewer URL handler?

  • Hi Rob,

    Apologies for the late reply. The RealVNC Viewer mobile apps should work with the same format. Are you seeing any errors when trying to launch the apps via URI?

  • Hi Bryan,

    The URI is installed as part of the RealVNC Viewer installation package - note that the "standalone" RealVNC Viewer won't install the URI handler to your system.

    Your connection string looks correct, how are you trying to launch it? e.g. as a link on a webpage?

  • On Android, I got this working by using "vnc" as the scheme. So "vnc://{ip/host}:{port}". Maybe the desktop also has a handler for it?

    It would be nice to be able to pass in the password as a param, though. Is that possible?

  • Can we specify "username" and "password" in the URI?
    That would be really convenient for the user.

  • Hi all,

    We are exploring extending the URI scheme to support additional parameters as part of our future roadmap.
