Alright, but why would I pay for your service over a VPS with one of those tools or Heroku? What part of the process do you take over or automate?

The plan is to automate from server provisioning to deployment but of course I cannot build integrations with all the cloud providers out there. In that case, you could buy the server, provide the IP address and credentials to log in and then the service does everything. Once the server is provisioned or added, you create an application from the dashboard and then git push to it. Will come with monitoring tools and alerts if you choose to set any. For those who can work Dokku and Flynn by themselves perhaps, it could be enough. But as compared to Heroku, you could save lots of money when you not paying for each app. Of course I need to mention the service itself could even be free and find other ways to make money.
