NetBeans is an integrated development environment (IDE) which has been developed primarily for Java, but also with other languages, in particular PHP, C/C++, and HTML5. It is also an application platform framework for Java desktop applications and others, and the NetBeans IDE is written in Java and can run on a variety of platforms like Windows, OS X, Linux, Solaris and other platforms supporting a compatible JVM.
The NetBeans Platform allows applications to be developed from a set of modular software components called modules. Applications based on the NetBeans Platform (including the NetBeans IDE itself) can be extended by third party developers.
