✓ Use when

Data engineering teams orchestrating ETL, ML pipelines, or cross-service data workflows who want Python-first ergonomics.

✗ Avoid when

Long-running stateful or transactional workflows with strict durability requirements — Temporal is stronger for microservice orchestration.

What is Prefect?

Prefect is an open-source workflow orchestrator where flows are plain Python functions decorated with @flow and @task. The hosted control plane (Prefect Cloud) handles scheduling, retries, observability, and run history, while execution happens on your own infrastructure via work pools. Popular with data engineering teams who find Airflow's DAG model rigid and who want something Pythonic.

Key features

✓Python-native @flow and @task decorators
