What Is Prefect?
Prefect is a workflow orchestration platform for data and ML pipelines. Most sources agree on the core structure, but conflict on Pro pricing and on older Starter and Team prices, and nearly all are third-party aggregators, so check prefect.io/pricing. Hobby is free with 2 users, 1 workspace, 5 deployments, 1 custom work pool, 500 minutes of Prefect Serverless a month and 7 days of run retention. Starter is $100 a month flat for up to 3 users, 20 deployments and 75 Serverless hours a month. Team is $100 per user a month, one source saying it has a 4-user minimum ($400 a month floor) and another listing 4 to 8 users, 1 workspace, 100 deployments and 225 hours a month. Pro is listed as custom in several sources, one giving $500 a month, and Enterprise is custom with SSO, object-level RBAC, SCIM, audit logs and IP allowlisting. Self-hosted Prefect Server remains free and open source.
One source gives Starter at $49, Team at $499 and Pro at $1,499 a month, which look stale. Prefect announced on July 13, 2026 that it is acquiring Dagster Labs, with financial terms undisclosed. Prefect and Dagster say both products continue independently, preserving open-source communities, roadmaps and commercial offerings, the combined company is expected to operate under the Prefect name from August 2026, and one source says pricing is unchanged for Prefect Cloud and Dagster+. Some aggregators describe the deal as completed while the primary pages describe an agreed acquisition, so closing is unverified.
Prefect suits Python teams that want orchestration with little boilerplate. Compare Dagster, Flyte and Metaflow. Browse the MLOps & Infrastructure tools directory for more.
