A Register Machine Simulator written in Rust and compiled to WebAssembly that runs directly in your browser. For syntax/usage instructions, as well as for a better-featured cli version, take a peak at the project's page on Github. To get started, write your code in the text box below and hit run. Note: the simulation is going to crash your browser tab, or make it appear unresponsive, if your code is too complex (or has an infinite loop) and max steps are set too high.
