What is Astronomer?
Astronomer is the commercial steward of Apache Airflow, staffing many of the project's top committers and PMC members. Its Astro platform runs Airflow as a managed service - hosted, hybrid, or in a customer's own environment via Astro Private Cloud - and the company has recently extended its pitch toward orchestrating agentic AI workflows in production. Pricing is usage-based (cluster, deployment, and worker costs per hour) for lower tiers, with Business/Enterprise tiers quoted directly.

Key capabilities
- Managed Airflow: Astro Runtime with hosted, hybrid, or private-cloud deployment options.
- Usage-based billing: Published per-hour rates for cluster, deployment, and worker costs on Developer/Team tiers.
- Enterprise options: Business and Enterprise tiers add 24/7 support, cross-region disaster recovery, and compliance features.
Core areas are Apache Airflow orchestration, pipeline observability, and - more recently - using Airflow as a control layer for agentic AI workflows.
Shortlist Astronomer if you're standardizing on Apache Airflow and want a managed or hybrid deployment maintained by the project's own committers, rather than self-hosting and patching Airflow yourself.
Because pricing combines cluster, deployment, and worker charges, model your actual DAG/worker footprint against Astronomer's calculator rather than comparing list prices alone.
