The use of NodeXL Pro requires a license key. We offer 12-month NodeXL Pro user licenses for commercial, academic/non-profit/government and student users. The software features of all license types are the same. Our pricing policy reflects the ability of our users to pay for a license. Your license purchase sustains the NodeXL project and the Social Media Research Foundation’s activities that enable us to continuously add new features to NodeXL Pro and related services like the NodeXL Graph Gallery.
