IntelliJ IDEA Ultimate

IntelliJ IDEA analyzes your code, looking for connections between symbols across all project files and languages. Using this information it provides indepth coding assistance, quick navigation, clever error analysis, and, of course, refactorings.  IntelliJ IDEA delivers major performance and usability improvements, including faster startup, easier installation of theme and keymap plugins, enhanced VCS workflows, and adds support for microservices frameworks, MongoDB and more.
