Hello, world! 👋
We've rebuilt data engineering for the data science era.
Prefect is a new workflow management system, designed for modern infrastructure and powered by the open-source Prefect Core workflow engine. Users organize
Flows, and Prefect takes care of the rest.
from prefect import task, Flow @task def say_hello(): print("Hello, world!") with Flow("My First Flow") as flow: say_hello() flow.run() # "Hello, world!"
Prefect's documentation -- including concepts, tutorials, and a full API reference -- is always available at docs.prefect.io.

Prefect is committed to ensuring a positive environment. All interactions are governed by our Code of Conduct.
From the Latin praefectus, meaning "one who is in charge", a prefect is an official who oversees a domain and makes sure that the rules are followed. Similarly, Prefect is responsible for making sure that workflows execute properly.
It also happens to be the name of a roving researcher for that wholly remarkable book, The Hitchhiker's Guide to the Galaxy.
Prefect requires Python 3.5+.
