SpidermonkeySharp | Managed mozjs.dll interface

SpidermonkeySharp is a C# library. SpidermonkeySharp has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Interact with the SpiderMonkey JavaScript runtime directly from C#. No custom native/managed bridge or wrapper DLL required. Just grab a recent build of mozjs.dll - from Firefox, for example - and get to work. Provides managed representations of JSAPI data structures and exposes native JSAPI entry points. Sitting atop the native data structures & entry points are convenient wrapper functions that handle marshalling strings and other data types. A second, higher-level layer on top of the wrapper functions provides managed classes and functions that dramatically simplify interacting with the VM, ideal for simple use cases. The high-level layer still exposes all the low-level pointers and values, so you can drop down to raw JSAPI when necessary. This library is still early in development, so many feature additions & performance improvements remain to complete. Please feel free to report issues using the GitHub tracker at
