Introducing Ruvy (2023)

We’ve recently open sourced a project called Ruvy! Ruvy is a toolchain that takes Ruby code as input and creates a WebAssembly module that will execute that Ruby code. There are other options for creating Wasm modules from Ruby code. The most common one is ruby.wasm. Ruvy is built on top of ruby.wasm to provide some specific benefits. We created Ruvy to take advantage of performance improvements from pre-initializing the Ruby virtual machine and Ruby files included by the Ruby script as well as not requiring WASI arguments to be provided at runtime to simplify executing the Wasm module.
