While most free IDEs have stood still or added non-core features, NetBeans has hewed closely to its mission of providing developers with an IDE that works fast and well with multiple languages. The latest release boosts NetBeans' market-leading support for Ruby and JRuby with remote debugging, significantly advances Groovy capabilities with out-of-the-box Grails support, expands C/C++ capabilities to include profiling, and enables unit testing in PHP.
