Red Hat launched openshift.io at Red Hat Summit 2017.
Its a SaaS based development environment, that provides everything you need to get up and running and start producing code. The marketing speak actually says is a "A free, end to end, cloud native development environment".
Just to reiterate - what openshift.io is going to provide for developers is a really convient hosteddevelopment environment to start their journey to developing apps for the cloud.
1. A deployment environment for your code native apps: You can use GitHub as your src repo, but deploy onto openshift to run your apps, for free (within limits). Red Hat wants to give developers the opportunity to run reasonable applications at no cost, but they don't have bottomless pockets, so there has to be some reasonable constraints - obviously you can chip in if you need more space/cpu.
2. A continuous deployment pipeline, that will enable you to run any code changes through test, stage to run, (which uses fabric8 and openshift pipelines under the covers).
3. A web based IDE, based on Eclipse Che, so you can edit your code in situ, without leaving openshift.io. This is a great feature for development, and allows you to develop and test the application you are building. However, if you don't want to leave the comfort blanket of your favourite IDE running on your laptop, and just push code to GitHub for openshift.io to pick up and deploy, that's OK too.
4. Analytics built in (using fabric8 analytics): to identify security risks in dependencies you maybe using, and also identify other dependencies that might be a better fit (e.g. flag you're using a really old version of commons math).
5. Agile management, to allow you to plan, and track development items for your code. This is really useful for collaborative development.
The fabric8 ecosystem also provides lots of developer tooling and examples to help developers get started.
