Voyant Server is a web application launcher for Voyant Tools – it makes it easy to run a stand-alone instance of Voyant Tools on your local machine, which has several potential advantages (performance, security, privacy, reliability, etc.) compared to the hosted version.
See the latest release and download the VoyantServer zip file. Unzip the file (be sure to actually extract the contents into a real directory) and double-click on the VoyantServer.jar file (on Macs you may need to Ctrl-click on the VoyantServer.jar, select open and confirm the opening – this is because of security precautions in OS X).
Once you open VoyantServer.jar a controller application will appear (that allows you stop stop the server, see error messages, change settings, etc.) and a new browser will also appear with Voyant Tools. That's it!
Voyant Server requires Java 11 and may not work with other versions.
If you receive an error message on Mac OS:
The Java JAR file “VoyantServer.jar” could not be launched. Check the Console for possible error messages.
You may open VoyantServer via the terminal as a workaround using: java -jar VoyantServer.jar
NB: you must run the above command from the directory into which you extracted the JAR file.
