Clang is a compiler front end for the C, C++, Objective-C and Objective-C++ programming languages. It uses LLVM as its back end and has been part of its releases since LLVM 2.6.

Its goal is to offer a replacement to the GNU Compiler Collection (GCC). Development is completely open-source, with several major software development companies involved, including Google and Apple. Its source code is available under the University of Illinois/NCSA License.

The Clang project includes the Clang front end and the Clang static analyzer among others.
