Astronomer Cosmos

Astronomer Cosmos is an open-source Python library that seamlessly integrates dbt (data build tool) Core projects with Apache Airflow. It allows users to orchestrate dbt models as native Airflow DAGs and Task Groups, providing enhanced observability, retries, and test execution directly within the Airflow UI. The library is actively maintained with frequent releases, evolving to support new dbt features like Fusion and various execution modes for optimal performance.
