Access to 6.3 and AEM "free" hosting



I am a developer, I want to develop on the platform and show the work I have done. Will there be such a version? I really don't mind if the code lives on Adobe's premisses I just want to be able to create code and show the work done. In addition, how do developers get a hold of AEM 6.3 if they haven't purchased a license but want to learn the platform?
