Intellij Idea also serves as a base platform for other IDE software: PhpStorm, PyCharm, RubyMine.

The Ultimate (commercial) version of the tool offers support for enterprise class development, while the open-source (free) version is often used for android, groovy, scala and web development. A 30-day fully functional trial of the Ultimate edition for various platforms can be freely downloaded.
