A WASM interpreter with dual modes — one as a browser-based VM and one as a simulator for WASM. It uses a structured parsing and execution pipeline in C++ & emscripten, to load binary modules , validate and decode instructions, and simulate a full virtual machine directly in the browser. It is a very useful tool when it comes to experimenting on systems safely and also helps out to build/test/debug any program in a sandboxed environment without requiring external runtimes.
