Prefect
PyPIprefectPrefect is a modern Python workflow orchestration framework and cloud platform, designed for data pipelines and ML workflows. It provides flow scheduling, retries, observability, and a hosted control plane (Prefect Cloud) with agent-based execution. Flows are deployed as Docker containers or as Prefect workers that pull work from cloud queues.
