NetBeans is Open Source
The NetBeans project is an open-source project. What this means is:
With the exception of content that explicitly specifies the license under which it is made available, the software and other content on this site is licensed under the Common Development and Distribution License, which complies with the Open Source Definition . Any third-party binaries included in /external/ directories in the source tree, are licensed under their own terms and conditions.

There are many more possible descriptions, ranging from the practical to the religious. The more important question is, does it work? After three years of existence, with participation from thousands of individuals and hundreds of companies (some of which have built their business on the software created here), we believe the answer is an unqualified "yes." But the best way to test this answer is to get involved in the NetBeans community and discover the benefits for yourself.
