I created PyGreen to be able to do the same thing but with an even faster startup. With it I don't need to create a base setup or copy-paste an old one. I just begin to work on the home page and exporting the style of the web site in a template takes like 10 seconds. And that's it, I spent 10 seconds on the coding of my website and I can use pygreen gen to get my static version to push on github pages.
Later, if I want, I can ditch the static version and add dynamic web pages. PyGreen does not use declarative markdown files, there is nothing that prevents you from adding completely dynamic stuff in the templates. It also uses Bottle, which is almost the same as Flask. So I can just add routes to Bottle and anything dynamic I could need then publish my app on a small server.
