Prefect vs Astronomer FAQ
- Which one is cheaper?
- One or both use custom pricing, so it depends on your specific needs.
- Can I use either one for free?
- Prefect has a free plan. Astronomer doesn't — though they do offer a free trial.
- How do they charge?
- Different approach here. Prefect uses hybrid pricing, while Astronomer goes with usage-based. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Prefect: They're positioned in the mid-market sweet spot — not trying to undercut Airflow's self-hosted free tier, but not as aggressively priced as Dagster Cloud or as enterprise-heavy as Astronomer. The $100/user/mo Team tier targets growing data engineering teams who've outgrown DIY orchestration but aren't ready for a six-figure platform deal. Astronomer: Astronomer is positioning as the managed Airflow premium — not the cheapest way to run pipelines, but cheaper than building and maintaining your own Airflow infrastructure at scale. They're going after data engineering teams already bought into Airflow who want to offload ops, competing with MWAA and Cloud Composer on convenience and Airflow fidelity.
