Airflow vs Prefect
Prefect's Pythonic flow API is easier to onboard a Python-first team to; Airflow's DAG-as-code has the larger operator ecosystem. Prefect 3 added transactional semantics for safer multi-write retries, closing a long-standing reliability gap. On price it is not close: Prefect Cloud Starter at $100 / month beats self-managed Airflow the moment any FTE is loaded, and a full 8-seat Team plan at $800 / month still does.
Pick Airflow when
- › Operator ecosystem breadth is a hard requirement.
- › Team is already invested in Airflow patterns.
- › Self-managed Kubernetes infrastructure exists.
- › DAG-as-code is the preferred mental model.
Pick Prefect when
- › Team is Python-first and values a Pythonic flow API.
- › Transactional semantics for write-heavy pipelines matter.
- › Managed cloud preference outweighs ecosystem breadth.
- › Dynamic workflows and parameterised runs are common.
