It should be pretty easy to look at the approach I took and mimic it for other providers. I write Open Source code for Microsoft, so we made it work with Azure first - but the code should be clean enough for someone else to pick it up and work in other stacks.

I should probably also mention that the engine running Azure Websites is open source itself (https://github.com/projectkudu/kudu), so you could just point it to your own engine.

Should be pretty easy to expand this out to work with any PaaS such as Heroku, Modulus, etc. For aws maybe we could work on getting it to deploy to Elastic Beanstalk? Might also be cool to generate a docker image.

definitely- working on breaking it out to be easily pluggable
