It's akin to JupyterLite, providing a temporary online Python notebook environment without the need to install any Python packages. It's potentially useful if you need to do a bit of quick interactive work in Python, but don't have the environment set up ready to do so.
Since actual jupyter kernels can't run in pyodide (they run as subprocesses and communicate over ZMQ), it uses an in-process Python kernel which runs on the same interpreter as the application itself.
Notebooks and files can be saved persistently to a local-storage based file system. It uses xterm.js as the terminal emulator (though I'm keen to test out ghostty-web).
