Is there a way to selfhost the gooddata platform? I see we have a docker for demo. Is that possible to host it in our cloud?

You can self-host GoodData.CN: https://www.gooddata.com/developers/cloud-native/doc/1.7/installation/ Generally, you can run both single container Community edition and Helm chart edition for production use cases. In the case of Community edition, you are limited to single organization (domain).

and it will have the same set of features like the CN ?

Both deployment options have the same feature set. In the case of helm chart deployment you need to obtain a license (for free).

I tested both demo and the cn version with a goodddata.cn free account, and i saw that the interface is a bit changed, and the features different(for ex, metric building, data loading)

The two platforms are not compatible. When you generate the react app, there is an option to pick the backend type: https://www.gooddata.com/developers/cloud-native/doc/1.7/integration/embed-insight/#embed-an-insight-using-gooddataui

npx @gooddata/create-gooddata-react-app --backend tiger

tiger

is the internal code name for GoodData.CN,

bear

is the code name for the hosted platform. You cannot integrate

bear

react app with

tiger

backend and vice versa. From the logs you sent, it seems that you generated an app with backend

bear

(bear API paths), but you try to connect to

tiger

.
