The main benefit of Baasil.io is that it offers developers a boilerplate/framework which they can extend with their own code (to build scalable realtime apps and services) - Any app/service built on top of this boilerplate can be automatically scaled to 1000 hosts/nodes using a single command.
Users don't have to use Baasil.io, but if they do, they will get the best possible support - For example, a customer can give us access to their Rancher control panel and this would allow us to SSH into their machines to help resolve any problems in a hands-on way.
It's probably more accurate to describe it as "DevOps as a service - With a focus on realtime apps/services".
The value proposition is probably closest to Cloud 66 http://www.cloud66.com/ except more focused on realtime apps.
Another similar service is Zeit.co https://zeit.co/ - Except Zeit.co only runs Node.js. Baasil.io can be extended with components written in any language.
