Dagster: Asset-centric orchestration with better data lineage tracking
Overview
What Prefect does
Prefect is a workflow orchestration platform built on an open-source Python framework that transforms regular Python functions into durable, production-ready workflows. Teams add simple decorators to convert functions into flows and tasks, without learning new frameworks or Domain Specific Languages. The platform handles scheduling, retries, state management, crash recovery, and monitoring of data pipelines and ML workflows at scale. Prefect Cloud provides managed orchestration with observability dashboards showing all workflow runs, task timelines, and performance metrics, while organizations can deploy within their VPC or use hybrid configurations for full control. The platform emphasizes durable orchestration where workflows heal themselves through built-in retries and state tracking, execute reliably across distributed infrastructure, and support multiple scheduling options including cron jobs, event-driven triggers, and backfills. Notable users include Cash App, WHOOP, Barstool Sports, and NASA.
What people use it for
- Orchestrating data pipeline workflows in Python

Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Prefect.
- Limited to Python-based workflows; other languages require API calls
- Hobby free tier severely limited for production use
- Team plan billing per user scales quickly with team size
- Less visual workflow builder compared to some competitors
- Smaller ecosystem of pre-built connectors than alternatives
