StarlingMonkey – SpiderMonkey-based JavaScript runtime

StarlingMonkey is a SpiderMonkey-based JavaScript runtime optimized for use in WebAssembly Components.

Its built-in functionality targets WASI 0.2.0 and provides a Component Model-based event loop.

The runtime implements important web platform APIs, including Fetch, WHATWG Streams and text encoding. Its modular architecture lets developers add custom built-ins and host APIs for specific deployment environments.

StarlingMonkey can evaluate dynamically loaded JavaScript or create specialized WebAssembly Components containing an application and its runtime. The latter approach offers faster startup and is suited to server-side JavaScript workloads.

This is free and open source software.
