In the Airflow 2+ there is "DAG dependencies" page (Browse menu item) that shows all DAG dependcies from other DAGs. Are there any analog in Airflow 3.0? I have not found any similar page.
Note: the question about DAG depdencies not tasks dependencies in one DAG
No, the "DAG Dependencies" page from Airflow 2.x is not available in Airflow 3.0. It was removed and there’s currently no built-in alternative in the UI to view DAG-to-DAG dependencies.
If you need that info, you'd have to extract it manually from your DAG code (e.g., checking for TriggerDagRunOperator).
