I'm attempting to run WAP Developer Edition for the first time. The instructions are to:

"On Windows, double-click the startup.bat file in the unzipped folder. The batch file starts the Node.js server in the Command Prompt window and Web AppBuilder in your default browser with http://[yourmachinename]:3344/webappbuilder. If the browser is closed, you can reopen Web AppBuilder in the same—or a different—browser as long as Node.js is running in the Command Prompt window."

The browser does not open automatically for me so I need to type in the URL.

How can I determine what [yourmachinename] is for my computer?

  • So you want to know how to look up your computer name with hostname? – Vince Dec 27 '18 at 13:00

You can use http://localhost:3344/webappbuilder/ or


find your computer name through the Control Panel:

  1. Open the Control Panel.
  2. Click System and Security > System.
  3. On the View basic information about your computer page, see the Full computer name under the section Computer name, domain, and workgroup settings.

(more info)


find the computer name under System Preferences > Sharing

  • Thank you for your reply, Gavin. Do you know how I can go about this on a Mac? I am running Mac OS High Sierra, not Windows. Thank you! – lisa.sedano Dec 29 '18 at 23:05
  • Actually, I think I figured it out. The page you linked to showed me what I should be googling for. I was able to find the computer name under System Preferences > Sharing. Thanks for your help! – lisa.sedano Dec 29 '18 at 23:07
