Eiffel is an free and open-source object-oriented programming language designed at Eiffel Software by Bertrand Meyer back in 1985. Bertrand Meyer had one goal in mind when he created the language, the goal of increasing the reliability of commercial software development. Today Eiffel comes with its own IDE (Integrated Development Environment) called EiffelStudio, the software can be used to write Eiffel code in a single user interface that includes a compiler, interpreter, debugger, browser, metrics tool, profiler, diagram and code inspector.

Haxe is an open-source, high-level, cross-platform, multi-paradigm programming language and compiler.
