In the page “Distributing your app” there is no mention of Volt.

A server of your own
This is the most powerful and permanent solution. It involves getting a website of your own with the appropriate settings. Select “Deploy to local server” or “Deploy to FTP Server” in Deploy options and fill in the Server, Path, Username and password.
There are a variety of own servers that you can use, for example Microsoft WebMatrix (IIS), Apache, Nginx, GWS to mention a few.
