Best for managed Airflow without running the servers
Astronomer's Astro is hosted Apache Airflow billed by the hour per deployment. A 14-day trial needs no card, but deployments, workers, clusters and add-ons are each billed separately, so you can't know the month's total in advance, and the top plans are quote only.
Who Astronomer is for
- Fits if you already write Airflow DAGs and don't want to run the servers
- Works for teams that want a trial with no card before committing
Who Astronomer is not for
- Pricey if you leave a deployment running all month, at $0.35 an hour before workers
- Skip it if you want a fixed monthly price, because workers, clusters and add-ons bill separately
- Tight if you're staying free, as there's only a 14-day trial
- Watch out: Business and above show a quote only, and cloud networking costs are passed through
Why Astronomer gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for money$0.35 an hour for a Developer deployment is about $255 a month if it runs all month, before worker hours. The category's dearest tenth starts at $165.
- CFree plan and trial14-day trial with no card. There's no free plan after that.
- CFeaturesHosted Airflow with deployments, observability and enterprise tiers. Business and above are quote only, and Astro Private Cloud has no published price.
- DEase of useNo store rating on record. You still write Airflow pipelines in Python and set up deployments.
- BPlatforms and integrationsWeb console on AWS, Azure and Google Cloud, with Snowflake in the mix. No desktop or phone apps.

Keep Astronomer, or make your own?
Keep it
To replace Astronomer you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 109 of the 134 other automation tools grade higher.
What you could not
- Connections to other products, each kept working as those products change.
- An AI agent, with the models and the safeguards behind it.
- Connections that pull numbers from dozens of other services.
- What a company asks for before it lets staff use something: single sign-on.
What this rests on. Astronomer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Astronomer?
Astronomer sells Astro, a fully managed platform for running Apache Airflow pipelines, and Astro Private Cloud for running it in your own environment. Pricing is metered by deployment size and worker hours rather than per seat, with higher plans adding observability, audit logging, SSO and support SLAs.
Worth knowing
- Deployments, workers, dedicated clusters, Observe and Otto are each billed separately, so the monthly total depends on usage.
- Prices shown are the monthly-billing view; Business and above show only a quote on the annual view.
- Networking costs are passed through from the cloud provider.
- Astro Private Cloud has no published price.
Key features
- Managed Airflow deployments
- Each deployment includes the scheduler, webserver and triggerer, sized to the Dag volume and billed at a fixed hourly rate by size.
- Workers that scale to zero
- Workers run individual Airflow tasks in seven sizes (A5 to A160) from $0.13 an hour and scale down when idle.
- Astro Observe
- Cost and performance metrics, root-cause analysis and lineage for Airflow pipelines, priced as a percentage of compute costs.
- Otto data engineering agent
- An agent for Airflow and Astro work, charged with an intelligence fee from $1.25 per million tokens plus model provider costs.
- Dedicated clusters and networking
- Standard multi-tenant clusters are included at no cost; dedicated single-tenant clusters start at $2.40 an hour.
- Private Cloud option
- Astro Private Cloud runs Airflow in your own environment, with multi-cluster management and air-gapped deployment support.
