How to launch YouTrack without letting it open a browser window? Follow

When you launch YouTrack as the jar file from the command line, it automatically opens a new browser window to display the main page. If you want to avoid launching the browser, you should use the "--no-browser" CLI parameter to your command. For example:

java -Xmx1024m -jar /Applications/youtrack-x.x.x.jar --no-browser 8000
