I know it's just for the early preview, but I find the fact that it's a PaaS selector hosted on Heroku amusing :)

Anyway, as for constructive feedback - I don't quite understand why many of the Framework options would exist. How does a PaaS "support" Spring? Or CodeIgniter? If a PaaS supports the language runtime, why would it need to explicitly support a framework?

Would be great to see Pivotal Web Services (powered by open source Cloud Foundry - http://run.pivotal.io) added to Paasifier. We have excellent support for all of the runtimes you consider (minus .NET currently), and quite a few of the data stores.

Nice! Would it be possible to filter the frameworks based on the language provided? Just a little bit of UX that would make it easier to use :)

Just a FYI:

The text on the splash image looks blurred because of the background shadow. Had me thinking I needed glasses. (Chrome 38, ubuntu 14.04)

You should also have some affiliate links on there.

This is a good idea. I would love it if I could see side-by-side comparisons of my options (especially price differences).

I think Google App Engine should be added

when I select "Java" runtime, I would expect to see java frameworks in the second drop down ... After playin' a little - "No PaaS Providers were found!" :(

What are you ranking the results by?

omg! exactly what I needed!

w00t!
