Sandstorm(.io) is very cool, and it does make managing your self-hosted web apps very easy. But it does not run Docker containers and it only runs on Linux x86-64. (There have been some attempts at running Docker containers with Sandstorm, but they are not easy to use.) Instead, the web applications must be specifically packaged for Sandstorm.
