The open source engine is called ChakraCore and is already published on Github, where developers can take a look and contribute fixes or improvements. Once all of those changes have been vetted, they can move into the Chakra engine that powers the Edge browser on Windows 10.
Microsoft said that ChakraCore can be built on Windows 7 SP1 and above, and that in the future it will work on supporting Linux and other platforms, as well. Therefore, developers won’t have to use Windows to work on ChakraCore. The company said that it wants developers to tell it which other platforms it should support, or they could start doing the porting themselves to their preferred platform.
