Sandstorm is great but apps really don't get updated anymore sadly. The founders also now have day jobs with CF, so probably don't get oodles of time to work on it.
Cloudron I've heard is excellent, completely dockerizes and automates everything with a slick webui, has lots of apps, however I just am unwilling to pay $15 a month for it.
Will likely roll my own apps/services with Rancher/haproxy/LE (or traefik as the reverse proxy/SSL term) on my sufficiently beefy Netcup rootserver KVM instance (at 8G should handle everything I want to do, but will likely use up most of it's resources which is fine).
