A web client for the python source cfg parsing/formatter library. It uses pyodide, a webassembly implementation of CPython, to enable the python library to run in the browser and therefor enable the application to be solely client sided and not in need of a backend.
The drawback of this is that it comes with an initial setup time of a couple of seconds, but nothing totally unacceptable as the page itself loads fast and informs the user of the separate initialization of the python interpreter.
