Acquia Site Studio http://drupal.org/node/2892988

Acquia Site Studio is the only low-code platform for the design, build and management of Drupal websites. Key features include:

• Page editor - The most powerful editing experience available for Drupal 8. Drag and drop page building using component based design AND full inline editing for quicker updates. Site Studio's component content is stored as structured JSON in a field on the page. A field formatter renders the content as HTML when requested.
  
  
  This means that Site Studio works out-of-the-box with workflow, revisions and translations. It also means that it works with Drupal's caching layers and cache tags system. Allows editors to use a specific component across the website but allows for styles to be selected to change the experience.

• Site builder - Build websites end-to-end through a visual, low-code interface. Site Studio includes an intuitive and powerful visual interface for creating all aspects of your websites. It’s low-code, not no code, so Site Studio is fully extensible and can work as a complete system or seamlessly with any custom development you may want to do.
  
  
  It allows site layout and style to be built by junior developers, designers and UX teams, releasing more valuable senior developer resources for complex coding and development tasks.

• Website settings - setup and manage your fonts, icons, colours and even the responsive grid in an easy to use interface. Want them available in a new install just export settings to your new website and you are ready to start building.
