WABT (https://github.com/WebAssembly/wabt/) and Binaryen (https://github.com/WebAssembly/binaryen) as well as the spec itself (https://github.com/WebAssembly/spec/tree/master/interpreter) all have interpreters for the WebAssembly language. What they don't have is the same import and export binding mechanisms that the JavaScript engines have. JS engines can bind wasm imports and exports with JS functions. The interpreters that exist today are great for testing implementations or compilers but don't have interesting capabilities to interact with an embedding environment. There have been a few experiments with non-JS embeddings (for example, implementations build on LLVM which could easily define bindings to native functions) but nothing really usable or productized yet.

As sunfish mentions below, this spec document is being conservative in describing things that are still being discussed. There are experimental implementations in Firefox, Chrome and Edge. See https://webassembly.github.io/demo/. There's more information about the current binary format here: https://github.com/WebAssembly/design/blob/master/BinaryEnco... There's a prototype spec interpreter here: https://github.com/WebAssembly/spec/tree/master/ml-proto There's a build waterfall testing multiple tools here: https://wasm-stat.us/console, including the experimental LLVM toolchain, the emscripten-wasm toolchain[0], binaryen[1], and sexpr-wasm[2]. WebAssembly is still under development, but I don't think it's fair to call it an early prototype. [disclaimer: I'm a WebAssembly contributor] [0]: https://github.com/kripken/emscripten/wiki/WebAssem
