Dokku
PaaS implementation to build and manage the lifecycle of applications
...Once it's set up on a host, you can push Heroku-compatible applications to it via Git. They'll build using Heroku buildpacks and then run in isolated containers. The end result is your own, single-host version of Heroku. Extensible Platform. Customize your PaaS. Write dokku plugins in any language. Share them online with others, and extend those already available. Dokku's simple core is easy to hack and add the features you need to get your job done.
