A feature request: I would absolutely love to have something like Arengu that also handles the rest of the boilerplate SaaS stack. Key is a branded user portal with a billing area (I should just give it my Stripe keys and let it generate the screens); user/team management, etc.

To give an example: if you click your avatar in the top right of a Github page, I would like to outsource all of those pages. (How would that work? I would provide APIs and then have some kind of page builder in Arengu that would display the data & handle user input. So for example if I were Github, I would have an endpoint that would return JSON for the repositories for a user, and Arengu would display github.com/$USER?tab=repositories. There could also be API contracts where my API essentially returns the HTML for part of the page.) Basically -- use your front-end builder to reduce the front-end code I need to write & manage.
