I stumbled upon a cool tool named Nativefier which converts a website into a desktop application, i.e. wrapping it in an executable. Can be installed from NPM and invoked like so:
npm install nativefier -g nativefier somewebsite.com
This downloads all resources from the URL and wraps these in an Electron application which can be distributed.
The resulting application is however a bit fat, easily consuming 90MB of storage. This is primarily due to Chromium and NodeJS being a part of Electron.
