Prefect 1 Core, Server, and Cloud are our first-generation workflow and orchestration tools. You can continue to use them and we'll continue to support them while users migrate to Prefect 2.
If you're ready to start migrating your workflows to Prefect 2, see our migration guide.
We recommend starting new projects with Prefect 2. If you have questions about specific use cases, see our Prefect Discourse discussions for more information.
# Automate all the things
If you can do it with Python, you can automate it with Prefect.
# Test local, deploy global
Workflows are developed and tested locally, then deployed for execution at scale.
# Simple but powerful
Prefect Cloud is powered by GraphQL, Dask, and Kubernetes, so it's ready for anything.
# Prefect
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 Tasks into Flows, and Prefect takes care of the rest.
Read the docs; get the code; ask us anything; chat with the community via Prefect Discourse!
# Hello, world! 👋
from prefect import task, Flow, Parameter
@task(log_stdout=True)
def say_hello(name):
print("Hello, {}!".format(name))
with Flow("My First Flow") as flow:
name = Parameter('name')
say_hello(name)
flow.run(name='world') # "Hello, world!"
flow.run(name='Marvin') # "Hello, Marvin!"
