Hi , we are planning to use supertokens for authN and authZ . I wanted to know  a comparison between open source solution and managed solution and what are the extra features provided by the managed solution of keycloak . Also is Oauth2.0 supported by managed solution

our managed solution offers management of the supertokens core. This means auto updates for security fixes and auto scaling.

Compared to keycloak, we don't force you to use Java, have better docs, are more customisable, you can build your own UI if you like and have better support
