About Prefect

Prefect modernizes workflow orchestration with a Python-native approach. Add @flow and @task decorators to existing Python functions — no DAG definitions, no boilerplate, no migration of existing code.

Automatic retries, result caching, concurrency limits, and parameterized runs handle production concerns. Event-driven triggers react to external events beyond simple schedules.

Modern dashboard provides real-time flow run visibility, log inspection, and alerting. Deployments package flows for scheduled or event-driven execution.

Prefect Cloud offers managed orchestration, team workspaces, and automations. Open-source Prefect Server provides self-hosted orchestration.
