System Requirements

NetLogo 1.1 User Manual

NetLogo is designed to run almost any type of computer, but you may experience problems with older, less powerful systems or older versions of system software. The exact requirements are summarized below. If you have any trouble with NetLogo not working on your system, we would like to offer assistance. Please write bugs@ccl.northwestern.edu.

Application or Applet?

There are two ways to run NetLogo:

Download application. This enables you to run NetLogo as a normal application. (Size of download: usually between 8 and 14 megabytes, depending on options.)
Run applet on the web within your browser window.

Running on the web is convenient, but downloading the application has some significant advantages:

Fewer compatibility issues with various operating systems and browsers.
Starts up faster and models run faster.
Window is resizable.
Edit menu is available.
Keyboard shortcuts for menu items are available.
