Kalmia started as a small hobby project about two months ago, but it quickly evolved when we needed a better solution to manage our office's documentation.

SamwiseOS is a persistent, single-page web app that looks and feels like a real operating system, complete with a terminal, a robust virtual filesystem (that saves to your browser's IndexedDB), user/group management, and even graphical applications. The twist? The entire core logic—filesystem, command execution, user management, everything—runs on a Python kernel powered by Pyodide (WebAssembly). The JS…
