Astronomer

Astronomer is a data orchestration company headquartered in Cincinnati, Ohio, United States, that has been the commercial steward of the open-source Apache Airflow project since 2018, helping enterprises coordinate and schedule complex data and AI workflows across many systems.

Its Astro platform is a managed Airflow service that provides a rebuilt scheduler and executor, a browser-based development environment, deployments managed as code, and native data observability with root-cause analysis; the platform reports supporting over 500,000 sustained concurrent tasks and is used by data engineering teams at organizations such as Booking.com and Together AI to move pipelines from prototype into production.

1. Managed Apache Airflow: Astro runs a hardened, rebuilt version of the open-source scheduler as a service.

2. High concurrency: the platform sustains large volumes of concurrent tasks with low start latency.

3. Deployments as code: teams manage environments and pipelines through Git-based workflows.

4. Native observability: built-in monitoring flags failures and highlights likely root causes.

5. Browser-based IDE: the Astro IDE lets engineers build and test DAGs without local setup.

6. AI-assisted operations: an Airflow-focused agent helps write DAGs and investigate failures.
