Actually you can just download it, stick the “public/” directory in a web server (or load it in your browser) and have it working without Electron, which I just did as a quick test:

Even save/load with “Export JSON” and “Import JSON” seems to work!

@antixk: since it works as a website anyway, I’d recommend doing that yourself because it’s much easier to give it a quick look this way.
