Prefect

Prefect is a workflow orchestration and observability platform designed for data engineering, machine learning, and AI agent workflows. Founded with the vision of simplifying Python-based automation, the company offers both open-source and cloud-based solutions that enable teams to build resilient, scalable workflows without rigid DAG structures or custom domain-specific languages. Their hybrid architecture ensures that customer data never leaves their infrastructure while still benefiting from managed orchestration capabilities. The platform serves as a unified control plane for diverse automation needs, from ETL pipelines and ML model training to event-driven automation and background task processing. Prefect's approach emphasizes developer experience through simple Python decorators, durable execution that enables workflow recovery without replaying completed steps, and comprehensive observability features. The company has earned trust from notable organizations including Cash App, Rent The Runway, Endpoint, Washington Nationals, and dbt Labs. Prefect differentiates itself through features like native data lineage tracking, work pools that decouple code from execution environments, and enterprise governance capabilities including SSO, role-based access control, and audit logging. With a community of over 25,000 developers and integrations spanning Docker, Kubernetes, AWS ECS, Google Cloud Run, Azure ACI, and Modal, Prefect positions itself as a modern alternative to legacy orchestration tools.
