3 tools to consider instead of Metaflow, shown against it.

Metaflow Kubeflow DVC MLflow
Vendor Outerbounds; originated at Netflix Kubeflow project (CNCF) Treeverse (lakeFS); formerly stewarded by Iterative Linux Foundation (LF AI & Data); originated at Databricks

Best for Data science teams wanting a lightweight Python framework to move pipelines from notebook to production. Platform teams that already run Kubernetes and want to orchestrate ML pipelines on their own infrastructure. Teams wanting Git-style version control and reproducibility for datasets, models, and pipelines. Teams wanting free, self-hostable experiment tracking without committing to a vendor's hosted SaaS.
Pricing

Metaflow the framework is free and open source; scaling costs come from the cloud compute/storage it's configured to use, and Outerbounds' separate managed platform is priced independently.

Pricing has not been verified yet — see the vendor's site.

Kubeflow is free, open-source software; costs come from the Kubernetes cluster and cloud infrastructure it runs on.
