Ory Kratos is nowhere near Keycloak. First of all, one needs at least Kratos+Hydra (there’s an integration method now out of the box yay) but Keycloak still has a flexibility advantage. Keycloak has many more features out of the box comparing to the complete Ory stack. The only thing nicer in Kratos from Keycloak is the standalone self-service UI with JSON identity declaration.
