Open-Source ChakraCore GitHub Repository
In the future, the company promises to bring support for other operating system platforms, starting with Linux platform. As Chakra’s JIT compiler is cleanly separated out which will help producing build configuration that builds just the interpreter and runtime, it will initially help enable cross-platform porting of ChakraCore. A roadmap for ChakraCore is also published on its GitHub repository.

What Is The Difference Between ChakraCore And Chakra?
Although, ChakraCore shares the same set of capabilities as we see in Chakra but there are two key differences. First, it does not exposes any private bindings of Chakra to the browser or the Universal Windows Platform. Second, ChakraCore supports a new set of modern diagnostic APIs instead of exposing the COM based diagnostic APIs available in Chakra.
If you are a developer and are excited about ChakraCore, the code is now available for download from the ChakraCore GitHub repository.
