Pricing in detail
Pricing is tied to task-runs, concurrency limits, and retention. The Pro tier handles roughly 1M task-runs / month at the published list price. Enterprise unlocks SSO, RBAC, and audit log retention.
Prefect 3.0's transactional semantics let pipeline authors group operations into a single atomic unit with rollback - useful for write-heavy ELT-and-activation flows.
When to pick Prefect Cloud
Pick Prefect when the team is Python-first and prefers a Pythonic flow API over Airflow's DAG-as-code or Dagster's asset-graph DSL. The 3.0 transactional model is a real differentiator for write-heavy pipelines.
Avoid Prefect when the team needs the largest ecosystem of community operators (Airflow) or first-class asset-graph semantics (Dagster).
Mid-market estimate
For a 50M-MAR mid-market profile, the published rate produces an estimated subscription line of $1,200/mo. Pro tier at ~1M task-runs/mo, list-price snapshot.source - pulled 2026-06-21Run the full TCO at /tco-calculator.
