NetBean as a Open Source

NetBeans is Open Source

The NetBeans project is an open source project. What this means is:

• The NetBeans Platform and IDE are free for commercial and non- commercial use.
• The source code to both are available to anyone to reuse as they see fit under the terms of the license.
• Development of the Platform and IDE happen in public. Decisions are made on public mailing lists, by consensus.
• Individuals or companies may contribute code to the project; participation is open to anyone.

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.

Why Open Source?

There are many reasons to choose the open source approach to creating software. This approach can be variably described as:

• A set of best practices for geographically distributed software development.
• A way of making sure software meets the needs of its users by ensuring those users can participate in its creation.
• A way of ensuring that users of software are able to modify it to meet their needs, and that no single entity can act against the interests of the project or the community.
• A way to create software that helps to ensure high quality by peer review and social dynamics (the "many eyeballs" concept).
• A way to create software that avoids the hierarchy and organizational politics than can make some commercial development efforts less efficient.

There are many more possible descriptions, ranging from the practical to the religious. The more important question is, does it work? Since 1998, with participation from thousands of individuals and hundreds of companies (some of which have built their business on the software created here), we believe that 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.

An Introduction to NetBeans

Most developers recognize the NetBeans IDE as the original free Java IDE. It is that, and much more! The NetBeans IDE provides support for several languages (PHP, JavaFX, C/C++, JavaScript, etc.) and frameworks. 

NetBeans is an open-source project dedicated to providing rock solid software development products (the NetBeans IDE and the NetBeans Platform) that address the needs of developers, users and the businesses who rely on NetBeans as a basis for their products; particularly, to enable them to develop these products quickly, efficiently and easily by leveraging the strengths of the Java platform and other relevant industry standards.

In June 2000, NetBeans was made open source by Sun Microsystems, which remained the project sponsor until January 2010 when Sun Microsystems became a subsidiary of Oracle. Please see our History section for more information.

The two base products, the NetBeans IDE and NetBeans Platform, are free for commercial and non-commercial use. The source code to both is available to anyone to reuse as they see fit, within the terms of use. The legal section contains information regarding licensing, copyright issues, privacy policy and terms of use.

The NetBeans project is also a vibrant community in which people from across the globe can ask questions, give advice, contribute and ultimately share in the success of our products. On the NetBeans mailing lists and forums, you will find posts from students, developers from top companies, and individuals looking to expand their skills.

A Brief History of NetBeans

NetBeans started as a student project (originally called Xelfi) in Czechoslovakia, now the Czech Republic, in 1996. The goal was to write a Delphi-like Java IDE (Integrated Development Environment) in Java. Xelfi was the first Java IDE written in Java, with its first pre-releases in 1997. Xelfi was a fun project to work on, especially since the Java IDE space was uncharted territory at that time.

The project attracted enough interest that the students, once they graduated, decided that they could market it as a commercial product. Soliciting resources from friends and relatives for a website, they formed a company around it.

Soon after, they were contacted by Roman Stanek, an entrepreneur who had already been involved in several startups. He was looking for a good idea to invest in, and discovered Xelfi. He met with the founders; they hit it off, and a business was born. The original business plan was to develop network-enabled JavaBeans components. Jaroslav Tulach, who designed the IDE's basic architecture, came up with the name NetBeans to describe what the components would do. The IDE would be the way to deliver them. When the specification for Enterprise Java Beans came out, it made more sense to work with the standard for such components than to compete with it--but the name stuck.

In the spring of 1999, NetBeans DeveloperX2 was released, supporting Swing. The performance improvements that came in JDK 1.3, released in the fall of 1999, made NetBeans a viable choice for development tools. By the summer of 1999, the team was hard at work re-architecting DeveloperX2 into the more modular NetBeans that forms the basis of the software today.
