Flows

A flow contains the instructions for workflow logic, including the @flow and @task functions that define the work of your workflow.

The Flows page in the Prefect UI lists any flows that have been observed by a Prefect API. This may be your Prefect Cloud workspace API, a local Prefect server, or the Prefect ephemeral API in your local development environment.

View a list of flows observed by Prefect in the Prefect UI.

For each flow, the Flows page lists the flow name and displays a graph of activity for the flow.

You can see additional details about the flow by selecting the flow name. You can see detail about the flow run by selecting the flow run name.
