Hasura Hub is a collection of boilerplates and readymade applications that you can clone, modify and deploy to kickstart your application development. For example - a react native project is wired up with a NativeBase UI kit, expo.io & a Hasura backend that you can clone and deploy in minutes. Hub also has sample applications for a slack bot, a messenger bot, e-commerce schemas, a simple AR app with AR Kit & Clarifai, etc.
The feature of Hasura that makes a ’hub' of instantly deployable projects possible is that every Hasura project is declarative, i.e, everything from source code to migrations to configuration is version controllable. The hasura cli, api console and hub are designed around and deeply integrate with this feature.

Hasura gives you dedicated (kubernetes) clusters on the cloud.
These run a bunch of open source components (nginx, postgres, redis) and a bunch of Hasura services (like data, auth, file APIs for apps). You can deploy your custom services on the hasura cluster as well (git push).
We have a free tier and then charge by the 'size' of the cluster. The fee is basically the underlying cloud provider's cost passed on directly to the user + a markup.
The Hasura backend APIs and platform glue are not open-source.
