LLVM is described as 'Modular compiler infrastructure supporting compile-time, link-time, run-time, and idle-time optimizations across various programming languages and platforms' and is a Compiler in the development category. There are seven alternatives to LLVM for a variety of platforms, including Linux, Windows, Mac, BSD and Cygwin apps. The best LLVM alternative is GNU Compiler Collection, which is both free and Open Source. Other great apps like LLVM are MinGW, clang, Tiny C Compiler and QBE.
