    Best for: Teams running Apache Airflow who want it managed, scaled and supported by Airflow specialists

    PaidWeb, Self-hosted

    64.8

    score / 100

    Cons

    • Deployments bill by the hour even when no tasks run
    • Only orchestrates Airflow, so it doesn't help if you prefer another framework
    • SSO enforcement and longer audit logs need the Business tier or higher
