A Simple HIPAA Compliant Web Application Using the Catalyze v2 API

Full transparency - I'm one of the founders of Catalyze. Yes, we do. We've been through a couple of 3rd party HIPAA audits. You're absolutely right - HIPAA is more than just backend security. All our internal policies are documented here (http://catalyze.io/policy) and their mapping to HIPAA is documented here (http://catalyze.io/hipaa).

I agree that you should not be tied to any solution that you choose. From what you're describing, it seems as though you'd like the entire backend to be portable. From a BaaS perspective, as you can imagine, that's a bit challenging. What we have done there is to document our APIs well and will shortly give you the ability to export your data as well. What you might be more interested in is our PaaS solution (https://www.catalyze.io/platform-as-a-service/) - that will allow you to use Heroku buildpacks to deploy you service onto our compliant infrastructure = so essentially if it works on Heroku, it will work on the Catalyze PaaS (or vice versa). We're hard at work on this and have a couple customers using it. We hope to have a public release very very shortly.
