Prefect Examples

This repository contains examples that demonstrate how to use Prefect. The example are intended to be starting points rather than complete solutions. We hope you find them useful!

Running these examples

Important

This repository uses uv for Python environment management.

If you've cloned the repository, you can run any of the examples with uv run flows/<example_name>.py, for example:

uv run flows/hello_world.py

If you haven't, you can point uv run at the URL of the Python file, for example:

uv run https://raw.githubusercontent.com/PrefectHQ/examples/refs/heads/main/flows/hello_world.py

Important

If you're not using Prefect Cloud, using deployment/scheduling functionality requires a Prefect server.

You can run a server locally:

uvx prefect server start

or instead in a docker container:

docker run -p 4200:4200 -d --rm prefecthq/prefect:3-latest -- prefect server start --host 0.0.0.0
