I'm looking for one such or a couple, can you enumerate?
- prose.io
- siteleaf.com
- statamic.com
- getkirby.com
- github.com/jekyll/jekyll-admin
- github.com/netlify/netlify-cms
- federalist.18f.gov
You can also always build your own on top of whatever generator you want to use (example: http://willschenk.com/building-a-gui-for-managing-middleman-...).
My favorite setup though is middleman + contentful + codeship. Static site generation happens with middleman. Content management happens with Contentful. Publishing happens with codeship.
