ChakraCore shares the same resources which Chakra supports in Microsoft Edge. Chakra and ChakraCore do however differ on two points: ChakraCore does not expose Chakra’s private bindings to the browser nor the Universal Windows platform. Moreover, instead of the Component Object Model based diagnostic API, new platform-independent diagnostic APIs will be used which could be standardized in the future if need be.
Currently, ChakraCore supports Windows only; in the future support should be expanded to additional platforms such as Linux. Gaurav Seth (Principal PM Manager, Chakra) says the following in this regard in the Windows-Blog:
As a first step towards this goal, we have cleanly separated out Chakra’s JIT compiler, producing a build configuration that builds just the interpreter and runtime. This smaller build target is what we will initially enable cross platform porting.
Roadmap should inform about planned targets
To make initial headway very soon, Microsoft hopes for an active Community. The ChakraCore-Team accepts feedback via Twitter @ChakraCore and in the ChakaraCore-Repository on GitHub. For further information on the engine, reviewing the following video is highly recommended:
