Prefect
Modern Python workflow orchestration with dynamic workflows and developer-friendly design
About Prefect
Prefect is an open-source workflow orchestration tool that helps data teams build, run, and monitor reliable data pipelines using Python. The platform turns fragile ETL processes into version-controlled workflows with features like retries, scheduling, logging, and state tracking. Prefect's key differentiator is its dynamic workflow approach, allowing workflows to be generated and modified at runtime based on data or external conditions. This makes it more flexible than static DAG-based tools like Airflow. Prefect provides a modern Python-first API that feels natural to developers, with strong support for async operations, distributed execution, and error handling. The platform offers both self-hosted and cloud options, making it accessible to teams of all sizes.
