Cling is described as 'Interactive C++ interpreter, built on the top of LLVM and Clang libraries. Its advantages over the standard interpreters are that it has command line prompt and uses just-in-time (JIT) compiler for compilation' and is an app in the development category. There are three alternatives to Cling for Linux, BSD, Mac and Windows. The best Cling alternative is Ch, which is free. Other great apps like Cling are Interactive GCC (IGCC) and CINT.

IGCC is a real-eval-print loop (REPL) simulator for C/C++ programmers. It allows you to type C++ commands which are immediately compiled and executed. Underneath it uses the normal GCC exe for compiling.
