The sources for ChakraCore are now available under the MIT licence at the ChakraCore GitHub repository. This choice of licence is interesting because MIT licence is one of the most liberal licenses — anyone is free to take the code and use it in open source and proprietary products.

ChakraCore may be just the beginning of Microsoft open sourcing its core user-facing technologies.
